Best Time to Visit Mount Cook: Weather, Seasons & Views
February and March are the best overall time for a first visit to Aoraki/Mount Cook, with fewer rainy days in the village than in spring, and long, mild evenings for walking. This guide compares the seasons, explains how cloud affects the views and the flights, and lets you check your own date.
If your dates are already fixed, use the date checker below to see the forecast, the hours of daylight and any winter road conditions for your day.
Day tours and scenic flights to Aoraki/Mount Cook are available year-round, although winter brings short days and snow and ice on the roads. In any month, the views depend first on the weather on the day. Cloud can hide the peak at any time of year. Scenic flights go only when the pilot can see the mountains, while day tours go ahead in rain or cloud.
If your dates are flexible, February and March offer the best overall balance for a first visit. The evenings are long and mild, Mount Cook Village has fewer rainy days than in spring, and the summer school holidays are over. February is warmer and sunnier, with more visitors to the Mackenzie area around Mount Cook and Lake Tekapo. March is cooler, with fewer visitors to the area and earlier sunsets. December and January have the longest days but fall in the summer school holidays. The lupins around Lake Tekapo, a stop on the day tours from Christchurch, flower from about mid-November into December in most years.
May and June have far fewer visitors to the Mackenzie area. They are cold and wetter than late summer at the village, and with sunset around 5pm, daylight is the main limit on a 12- to 13-hour day tour. From June to August the Hooker Valley Track can be icy, and the conservation department recommends microspikes and poles. Snow can also close the road into the village, so check road conditions before you travel. Book a scenic flight for early in your stay, so a weather cancellation can be moved.

- About 9 and 16 days with rain at Mount Cook Village in February and October, so late summer gives you the most dry days to walk and fly
- About 9:20pm and 5:10pm sunset at Mount Cook in mid-January and mid-June, so a winter day tour drives home in the dark
How the seasons compare at Mount Cook
| If you want | Choose | Keep in mind |
|---|---|---|
| The best overall balance | February and March | February is still busy; March has earlier sunsets |
| Long days and summer warmth | December and January | Summer school holidays; January had the most visitors in 2025 |
| Lupins around Lake Tekapo | Mid-November into December | The timing moves a little from year to year |
| Far fewer visitors | May and June | Cold, among the wetter months, and short days |
| A winter landscape | June to August | Icy tracks, possible road closures, sunset around 5pm to 6pm |
February and March are late summer and early autumn at Mount Cook. The village averages about 9 days with rain in February and 10 in March, against 15 to 16 in May, September and October, so you have the best chance of dry days for the Hooker Valley Track and for flying. Average highs are about 21°C in February and 18°C in March, and the sun sets around 8:50pm in mid-February and 8pm in mid-March. February is the warmer and sunnier month, with about 172 hours of sunshine against 158 in March, but it is still one of the busiest months in the area. March is quieter, and the clocks go back on the first Sunday in April, so by mid-April sunset is around 6pm.
December and January are the warmest and longest days of the year, with average highs of about 19 to 20°C and sunset after 9pm. The New Zealand summer school holidays run from just before Christmas to late January or early February, and in 2025 January had more visitors staying in the area than any other month, so book a tour or a flight ahead if your dates are fixed.
Other experiences you might enjoy
Most trips to Aoraki/Mount Cook also take in Lake Tekapo, with the Church of the Good Shepherd and stargazing in the Aoraki Mackenzie International Dark Sky Reserve, the turquoise water of Lake Pūkaki, and, for some, the drive on to Queenstown or back to Christchurch.
How the park changes through the year
Summer, December to February. The warmest months at Mount Cook Village, with average highs of about 19 to 21°C and the most sunshine of the year. It is also the main school-holiday season, and the Glacier Explorers boat sails among the icebergs on Tasman Lake. Around Lake Tekapo the lupins flower from about mid-November into December in most years.
Autumn, March to May. March is still mild, with an average high of about 18°C, and has fewer rainy days than spring. April’s average high is about 15°C, with about 12 days of rain, and after the clocks go back in early April the evenings close in, with sunset around 6pm. May is colder, with an average high of about 11°C, and wetter, with about 15 days of rain, and far fewer people visit.
Winter, June to August. The coldest months, with average highs of about 7 to 9°C, lows below freezing and around 9 hours of daylight in June. The Hooker Valley Track can be icy in shaded places, and snow can close the road in. June is the quietest month for visitors in the area. The Glacier Explorers boat does not run in July and August. Ski plane flights still land on the Tasman Glacier, which holds snow all year.
Spring, September to November. Days lengthen quickly after the clocks go forward on the last Sunday in September, and by November sunset is around 8:45pm. October has the most rainy days of the year at the village, about 16, and September about 15, so keep a spare day if you are flying. Visitor numbers rise through November, and the lupins start to flower around Lake Tekapo.
Cloud, the views and the flights
Mount Cook Village sits at about 730 m at the head of the Hooker and Tasman valleys, under the Main Divide, and it has rain on about 156 days in an average year. DOC warns that the weather in the national park changes quickly, with strong wind, heavy rain and snow possible at any time. Cloud can hide Aoraki in any season, and a clear morning can cloud over by the afternoon. The monthly figures tell you how often the village is dry; only the forecast can tell you about your day.
The day tours on this site run in rain or cloud, so unless snow closes the road you will reach the national park whatever the sky, and you can still walk the tracks and see the Tasman Glacier from the viewpoint when the peak is hidden. Scenic flights and ski plane landings need the pilot to see the mountains. Mount Cook Ski Planes aims to give notice the day before if the weather looks likely to affect a flight, and it makes the final call on the day, from early morning up to about 10 minutes before departure. If it cancels for weather, it offers a full refund or a new date at no extra cost.
Mount Cook Ski Planes also says many guests book their flight for their first day in the area, so there is time to move it if the mountain weather is not suitable. That advice holds in every month. Neither it nor the other operators we checked publishes cancellation rates or a best hour to fly, so this page does not rank months by cancellations.
Daylight on a day tour
A day tour from Christchurch takes about 13 hours including pickup and drop-off, with roughly 8 of those hours on the road, and a day tour from Queenstown about 12 hours. Daylight matters more on these long days than the temperature does. From November to February you have 14 to 15 hours of daylight, so you see the whole drive. In June there are about 9 hours, with sunrise after 8am and sunset around 5pm, so part of the drive out and the drive home are in the dark. The date checker below shows sunrise and sunset for your date.
Weather and visitors, month by month
The weather figures are long-term averages for Mount Cook Village, where the day tours stop and the walks start. The airport where most scenic flights leave from is a few minutes down the valley, and the glacier landing sites are far higher and colder. The visitor column counts people staying in commercial accommodation across the Mackenzie District in 2025; it shows how busy the area is, not how full a tour will be.
| Month | Average high and low | Days with rain | Sunshine hours | Sunset, mid-month | Visitors staying in the district, 2025 |
|---|---|---|---|---|---|
| January | 20°C and 9°C | 11 | 184 | 9:21pm | 96,000 |
| February | 21°C and 9°C | 9 | 172 | 8:49pm | 81,000 |
| March | 18°C and 7°C | 10 | 158 | 8:02pm | 79,000 |
| April | 15°C and 4°C | 12 | 124 | 6:07pm | 67,000 |
| May | 11°C and 1°C | 15 | 86 | 5:25pm | 46,000 |
| June | 8°C and −1°C | 14 | 73 | 5:08pm | 40,000 |
| July | 7°C and −2°C | 13 | 80 | 5:22pm | 52,000 |
| August | 9°C and −1°C | 14 | 113 | 5:53pm | 51,000 |
| September | 12°C and 2°C | 15 | 121 | 6:27pm | 54,000 |
| October | 14°C and 3°C | 16 | 152 | 8:02pm | 60,000 |
| November | 16°C and 5°C | 14 | 166 | 8:44pm | 75,000 |
| December | 19°C and 7°C | 14 | 179 | 9:18pm | 88,000 |
A day with rain here is one with at least 1 mm. For comparison, Lake Tekapo, about an hour and a half’s drive away on the day tours, is far drier, with rain on about 75 days a year, so the weather can be quite different at the two stops on the same day.
Which tour suits which season
- Mount Cook & Lake Tekapo Day Tour from Christchurch runs all year, in rain or cloud, with about 2.5 hours of free time in the national park, a stop at the Tasman Glacier viewpoint and 30 minutes at Lake Tekapo. In winter, part of the drive is in the dark.
- From Queenstown: Mt Cook & Hooker Valley Day Tour is the day tour from Queenstown, about 12 hours, and suits the long days from October to March best.
- Tekapo Shuttle: Mt Cook Day Tour via Pukaki & Tasman Lake is a shorter day from Lake Tekapo, so it fits a short winter day better than a tour from the cities.
- The ski plane and helicopter glacier combo lands on the Tasman Glacier, which holds snow all year, so it is the flight to book if you want snow underfoot in summer.
- The 25-minute helicopter flight with an alpine landing is the shorter, cheaper flight; its alpine landing site may have no snow from roughly December to March.
- The 3-hour Tasman Glacier heli-hike puts you on the ice with a guide; like every flight here, it goes only if the weather allows.

In general, day tours and scenic flights to Aoraki/Mount Cook are available all year. Day tours run in all weather, while flights go only when the pilot can see the mountains, and cloud can hide the peak in any month.
Averages are NIWA figures for Mount Cook Village, and the forecast is from Open-Meteo for the same place. Sunrise and sunset are calculated for the village in New Zealand time. For severe weather warnings, check MetService’s Aoraki/Mount Cook National Park forecast, and for road closures the NZTA journey planner.
The tours on this site can be cancelled free up to 24 hours before they start when booked through GetYourGuide. If your booking has the same terms, you can book once your dates are fixed and look at the forecast before the deadline. Booked directly with an operator, the terms can differ, so read the specific booking terms before you rely on them. If a flight operator cancels for weather, it offers another date or a refund.
How we know
Sources and limits
Temperature, rain and sunshine. NIWA climate averages for 1991 to 2020 at Mount Cook Village (730 m), from NIWA’s CliFlo national climate database as tabulated on Wikipedia’s Mount Cook Village page, read on 2 November 2026: mean daily maximum and minimum, days with at least 1 mm of rain, and sunshine hours. We could not open CliFlo itself, so we checked the rain days against NIWA’s own publication, The Climate and Weather of Canterbury (second edition, 1981 to 2010 averages). It gives 153 days a year with at least 1 mm at the village (171 counting days with any measurable rain), with February the lowest at 10 and March at 12, against 13 to 15 from September to December. February has the fewest rainy days in both series, and February and March have fewer than spring in both; the older series does not separate March from the winter months, so the page does not claim it does. Lake Tekapo’s rain days are from the same source for Lake Tekapo (1991 to 2020). The glacier landing sites have no published normals, so the page says only that they are higher and colder.
Sunrise, sunset and daylight. Calculated for Mount Cook Village with the standard solar formula, in New Zealand time with daylight saving, which ends on the first Sunday in April and starts on the last Sunday in September (govt.nz). Mid-month times are for 2027 and are accurate to a few minutes. The date checker shows the times for your date.
Visitors. MBIE Accommodation Data Programme, guest nights in commercial accommodation for the Mackenzie District in 2025, read through Figure.NZ on 2 November 2026 and rounded to the nearest thousand. Mackenzie Tourism notes that figures from July 2025 are estimates because MBIE paused publication. The series covers the whole district, including Lake Tekapo and Twizel, leaves out holiday homes and short-stay rentals, and does not count the people on any one tour.
Tracks, roads and winter. DOC’s Hooker Valley Track page (icy in shaded areas in winter, microspikes and poles recommended; the track is designed to avoid avalanche risk; snow can close State Highway 80), read on 2 November 2026. Road status: NZTA journey planner.
The tours and flights. The GetYourGuide listings for the day tours (13 hours from Christchurch with about 8 on the road, runs in all weather; 12 hours from Queenstown), checked live on 2 November 2026. Mount Cook Ski Planes & Helicopters’ FAQ (notice the day before when possible, final call up to about 10 minutes before departure, full refund or reschedule if it cancels for weather, many guests book their first day in the region; glacier landings give snow all year, the alpine site may have none in warmer months), read on 2 November 2026. Glacier Explorers’ season (September to June) from Mackenzie NZ’s operator page, read on 2 November 2026. Lupins: Discover New Zealand and operator listings on newzealand.com, which give late November to December and mid-November to early January; no official body publishes a flowering calendar, so the page gives the overlap.
School holidays. Ministry of Education term dates for 2026 and 2027, read on 2 November 2026; the end of the summer holidays varies by school.
What these numbers cannot tell you. None of the operators we checked publishes cancellation rates, a best hour to fly, or how often Aoraki is clear of cloud, so the page ranks none of them. Days with rain are the closest monthly measure of how often the sky is clear at the village. Monthly averages cannot tell you the weather on your day; the forecast in the date checker can, within about two weeks.
For more on the trip itself, see Mount Cook tours from Christchurch, from Queenstown and the Tasman Glacier heli-hike.
Frequently asked questions
What is the best month to visit Mount Cook?
If your dates are flexible, February and March offer the best overall balance. Mount Cook Village averages about 9 days with rain in February, the fewest of the year, and about 10 in March, the evenings are still long and mild, and the January peak in visitors is over. February is the warmer and sunnier of the two; March is quieter. In every month, how much of the mountain you see depends on the cloud on the day.
When is Aoraki/Mount Cook most likely to be clear?
No month guarantees a clear view. Mount Cook Village has rain on about 156 days in an average year, and the peak can be in cloud in any season. The village has the fewest rainy days in February, fewer in March than in spring, and the most sunshine from November to February, so late summer gives you the best chance across a stay. Check the forecast for the village in the days before, and keep a spare day if seeing the peak matters most.
Is it worth visiting Mount Cook in winter?
Yes, if you plan around the short days. From June to August average highs at Mount Cook Village are about 7 to 9°C, sunset is around 5pm to 6pm, and far fewer people visit in June. The Hooker Valley Track can be icy in shaded places, so DOC recommends microspikes and poles, and snow can close the road into the village at short notice. Day tours still run, but much of a 12- to 13-hour tour is in the dark, including the drive home.
When do the lupins flower at Lake Tekapo?
Lupins flower around Lake Tekapo and along the roads of the Mackenzie Basin from about mid-November into December in most years, and the timing moves a little from year to year. Most day tours from Christchurch and Queenstown stop at Lake Tekapo on the way to Mount Cook.
Do Mount Cook day tours run in bad weather?
Yes. The day tours on this site go ahead in rain or cloud, so dress for cold, wind and rain in the mountains. If snow closes the road, the operator may change or cancel the tour. Scenic flights are different: they go only when the pilot can see the mountains, and Mount Cook Ski Planes makes the final call on the day, up to about 10 minutes before departure. If it cancels for weather, it offers a full refund or a new date.
When does the Tasman Lake boat trip run?
Glacier Explorers runs its boat trip among the icebergs on Tasman Lake from about September to mid-June, and not in July and August. It is booked directly with The Hermitage, not on GetYourGuide or Viator. On other days, the Tasman Glacier viewpoint walk from the Blue Lakes car park looks over the same lake.
When is Mount Cook busiest?
In 2025, January was the busiest month for visitors staying in the Mackenzie District, which includes Mount Cook Village, Lake Tekapo and Twizel, followed by December and February. June and May were the quietest. These figures count people staying in commercial accommodation across the district, not passengers on any one tour, so book ahead in summer if your dates are fixed.
