Choosing when to visit Fox Glacier comes down to how you want to see the ice. The West Coast receives heavy precipitation throughout the year. You need to weigh warmer hiking temperatures against the need for clear skies if you book a helicopter tour.
What is Fox Glacier like in summer?
Summer (December to February) brings the warmest temperatures for walking the South Side Walkway.
Daytime temperatures are mild, making it comfortable to hike the 6.4-kilometer return track. However, summer also brings frequent rain showers. Heavy rainfall can cause localized flooding or road closures on State Highway 6. Pack a waterproof rain jacket and insect repellent for the sandflies.
Why is winter a good time for helicopter tours?
Winter (June to August) often provides calmer, clearer skies, which lowers the chance of flight cancellations.
Helicopter flights are highly weather-dependent. If you want to land on the ice or do a heli-hike, winter is the most reliable season. The cold air brings crisp, stable weather systems. You must wear warm, non-cotton layers, a hat, and gloves during a winter visit.

How often are Fox Glacier flights cancelled?
Helicopter tours are frequently cancelled or rescheduled due to poor weather.
The glacier valley acts as a steep funnel, and the area receives heavy precipitation. Low cloud cover, high winds, or heavy rain will ground all flights. Always check the weather forecast and allow a flexible day in your itinerary in case you need to rebook your flight.
Does weather affect the free valley walk?
Yes, heavy rain can flood tracks and increase rockfall hazards.
Always check current track conditions at the DOC Visitor Centre before you start the Fox Glacier South Side Walk. Sudden heavy rain causes localized flooding. You must stay on marked tracks and behind safety barriers due to extreme landslide hazards.

What should I wear for the unpredictable weather?
Layering is essential because conditions change rapidly on the West Coast.
- Footwear: Sturdy, closed-toe hiking boots or trail runners.
- Outerwear: A waterproof rain jacket is essential.
- Layers: Warm, non-cotton mid-layers like merino wool or fleece.
- Accessories: Sunglasses to block high UV glare from the ice.
Questions travellers ask
Can I visit Fox Glacier year-round?
Yes, Fox Glacier is accessible year-round. The South Side Walkway is open daily unless temporarily closed by DOC for severe weather or flooding.
What happens if it rains during my visit?
You can still hike the valley track in the rain, provided DOC has not closed it for safety. However, helicopter flights will be cancelled or delayed until skies clear.
Should I book my heli-hike in advance during winter?
Yes. While winter has clearer skies, flights still sell out. Book ahead and leave a flexible day to accommodate potential weather delays.
