03Fewest wet days: March and July, with 13 days each of 1 mm or more at Franz Josef.¹

Rain in every month

The West Coast is New Zealand's wettest region, and NIWA puts annual rainfall at high elevations regularly above 10,000 mm, with low coastal sites typically getting 2,000 to 3,000 mm.³ DOC adds that Westland Tai Poutini National Park lies in the path of the prevailing westerly winds, which can bring heavy rain at any time of the year, with up to five metres falling annually.⁴

Our month-by-month figures come from NIWA. Rain and wet days are the 1981 to 2010 normals for Franz Josef, the nearest NIWA rain station, about half an hour north; temperatures are NIWA's 1991 to 2020 averages for Hokitika, the nearest station with temperature normals on this side of the Alps.¹ Even the driest month there has 352 mm of rain, in July.¹ The wettest is December, with 659 mm.¹

Those totals sound alarming, but they arrive in bursts. A day of heavy rain is often followed by clear, washed air, and those clear spells are when the helicopters fly and the lakes reflect. The best time to visit Fox Glacier is therefore less about the month than about leaving room in your plans for the good day to come to you.

Summer: long days and full bookings

Fox Glacier in summer means long days and the warmest weather. In January the sun is above the horizon for 15.1 hours at mid-month, and the average high is 19.5 °C.¹ February edges ahead as the warmest month: its average high is 19.9 °C and its low 12.1 °C.¹ Rain does not stop: January has 14 wet days and 567 mm.¹

Summer is also the busy season. DOC says the Lake Matheson walk gets busy from November to April.² Heli-hikes and flights fill up, and the best morning slots go first, so book early and arrive the night before. DOC's March 2026 release noted that some of the approved landing sites are affected particularly during peak periods.⁵

The upside is the light. Long evenings give you time for a heli-hike in the morning, a rest, and Lake Matheson or Peak Viewpoint at sunset. Sandflies are at their keenest in the warm months, so insect repellent is part of the summer kit.

Autumn: settled spells and fewer people

March and April keep much of the summer warmth. March has an average high of 18.8 °C and 13 wet days, the joint lowest count of the year.¹ April has 14 wet days and an average high of 16.6 °C.¹ The days shorten quickly, from 12.5 hours of daylight in mid-March to 10.9 hours in mid-April.¹

By May the season is clearly changing. The average high falls to 14.6 °C and the low to 6.5 °C, with 15 wet days.¹ DOC's busy season ends in April, and after that it can be easier to change a booking at short notice when a clear day appears.²

Autumn suits travelers who want space more than warmth. The forest walks are quieter, the light is softer for photographs, and the snowfields above the glacier start to whiten again. Pack a proper warm layer for the evenings and early mornings.

Winter: cold nights, clear mornings

Winter is the coldest and darkest time, but not the wettest. July shares the fewest wet days, 13, with March, and has the least rain, 352 mm.¹ Its average low is 3.1 °C and its average high 12 °C.¹ June has the shortest days, with 9 hours of daylight at mid-month.¹

NIWA describes lowland temperatures on the West Coast as mild all year, with frosts below 0 °C and days above 25 °C both infrequent compared with most other regions.⁷ That mildness at sea level sits under snow-covered peaks, which can make winter mornings look spectacular from the township and from Lake Matheson.

Winter also has practical advantages. The busy season is over, so you can often choose your slot, and a cold, still morning can give very clear air. The trade-off is short days: plan one activity per day and keep driving for daylight.

Spring: the most wet days

Spring brings the most wet days in the averages. September has 18 wet days and 505 mm of rain.¹ October is wetter still, with 19 wet days, the highest count of the year, and 595 mm.¹ Temperatures climb slowly, with an October high of 14.9 °C.¹

Daylight returns fast. Mid-October has 13.2 hours of daylight, and mid-November 14.6 hours.¹ November averages 16 wet days and a high of 16.3 °C, and marks the start of DOC's busy season.¹ ²

If your trip falls in spring, build in a spare day and book flexible activities. The waterfalls along the valley walls are at their best after rain, and the forest is lush and loud with birdsong. Clear days still come, and when they do they feel like a reward.

How weather decides your glacier day

Whatever the month, the heli-hike and the flights run only when the weather allows. The heli-hike listing says every trip depends on favourable weather, and the provider recommends booking your first available day in Fox Glacier for flexibility. The confirmed time may differ from the one you asked for.

Free cancellation up to 24 hours before helps you plan around the forecast, and you can reserve now and pay later. For a flight, the 35-minute Fox and Mount Cook trip offers an alternative date or a full refund when poor weather cancels it.

Use the forecast, but do not trust it blindly in the mountains. Cloud can sit on the glacier while the township is in sunshine, and a grey morning can clear by noon. Stay in touch with your operator, keep your phone on and be ready to go when they call.

Planning a visit around the averages

Averages describe the long run, not your week. A month with many wet days can still hand you a run of clear mornings, and a dry month on paper can deliver a week of cloud. Read the numbers as odds rather than promises, then book the things that need clear weather as early in your stay as possible and keep the walks for the grey hours.

The simplest rule is to give Fox a second night whenever you can, so that a cancelled flight can move to the next morning. If you travel in the busy months, book the heli-hike well ahead and still keep the spare day. If you travel in the quiet months, you can often book at short notice and pick the clearest forecast.

Pack for every season whatever the calendar says. Even in summer the air on the glacier is cold, and even in winter the sun on the snow is strong. A waterproof jacket, a warm layer, sunglasses and sunscreen cover almost every day on the West Coast.

Changing snow and ice through the seasons

The glacier itself has a seasonal rhythm. Earth Sciences New Zealand flies its end-of-summer snowline survey each March, after the end of summer, and has done so since 1977.⁶ The survey measures how much of the previous winter's snow survives to feed the glaciers.

In 2026 it saw retained snow on some glaciers but no reversal of the overall trend of ice loss.⁸ For a visitor, that means the upper snowfields are whitest after winter and in spring, and the bare blue ice of the lower glacier shows best in late summer and autumn.

Neither is better, only different. A heli-hike in late summer shows you more bare ice, crevasses and blue colour; a snow landing in spring puts you on a deep white field. Choose your season by the picture you want, then let the weather pick the day.
