Introduction

Waking or hiking in New Zealand can be a breathtaking experience, thanks to its vast, diverse landscapes. However, the country’s unique location and geography mean the weather can change in the blink of an eye.

Here’s my friendly guide to help you navigate New Zealand’s weather, so you can make the most of your hiking trips. If you’re not sure which walk is best for you, you can learn how to choose a walk.

How Geography Affects the Weather

New Zealand is split into two main islands: the North and South Islands. The North Island typically sees a subtropical climate, meaning it’s warmer, while the South Island is cooler with a temperate climate.

The mountains and oceans around both islands can cause quick and surprising shifts in the weather. So, don’t let a sunny morning fool you – it could be raining by lunchtime!

Check you have the right safety gear for walking in New Zealand.

What to Expect Each Season

Summer (December to February):

This is my favourite season for walking because it’s usually warm and sunny. Still, it’s a good idea to pack a rain coat and some layers; those mountain areas can get chilly and wet even in summer.

Autumn (March to May):

Cool, crisp air and less crowded walks make autumn a great time for hiking. The changing leaves are mega pretty too, especially in Central Otago in Wanaka or Queenstown.

Winter (June to August):

It gets cold, and the high mountain tracks often see snow, especially in the South Island. Some tracks might be too slippery or blocked, so check which walks are good to go before you head out.

Spring (September to November):

Spring weather can be a mixed bag—sun, wind, rain, you name it, and usually all in one day! Melting snow also means rivers can be high, and trails can be muddy. But the blooming wildflowers are worth it, especially in places like Lake Tekapo.

Local Weather Quirks to Watch For

Nor’westers: These are warm, dry winds that hit the South Island and can make things suddenly hotter. They’re a good reminder to carry extra water, a hat and sunscreen.

Foehn winds: These guys are like nor’westers but can cause drastic temperature jumps. If it suddenly feels like you’re walking in shorts weather, you know why!

Rain: Rain loves to hang out on the west coast of both islands, thanks to those tall mountains. Even if it’s sunny when you start, always have a raincoat handy.

Tips for a Safe and Enjoyable Hike

  • Check the forecast: The New Zealand MetService website is your go-to for up-to-date weather info.
  • High tides: For any beach walks requiring a low tide crossing, check the tides first.
  • Dress smart: Layers are your friend. And waterproof gear is a must-have, no matter the season.
    Tell someone your plans: It’s always smart to let someone know where you’re going and when you plan to be back.
  • Know your limits: If the weather turns bad or a walk looks too risky, it’s okay to turn back. Better safe than sorry!
