Sometimes you wonder if the weather actually cares what season it is in New Zealand. We have compiled some local knowledge to help guide you to the best time for your hiking adventure.


Geography 101 - continental verses oceanic

New Zealand is a long thin land 'floating' in a bathtub of ambient water. The 90% of NZ where we live, work and play is never that hot or cold because the ocean influences it. Sure, we call it cold, but most Americans and Europeans mock us when they realise how benign it really is here - both in summer and winter. Sure, want to freeze in winter? Head to the alps. However, in a global climate sense, benign is the word you are looking for to describe the New Zealand climate. Which is why we have tropical-like forests that never lose their leaves in winter.

Day length, although not super seasonal (think northern Morocco to Bordeaux or LA to Seattle), is as much the metric to take account of as temperature and weather. The day length limits what you can achieve in the outdoors. The south in mid winter has only 9-10 hours of day light. Take a book for those long nights.


The rules - what rules?

There are plenty of exceptions to the rules in New Zealand's climate. The weather is generally changeable and varies hugely from east to west (across the ranges). Warmth, rain, sun, snow, hail, can happen any time of year and anywhere in this temperate, ocean-controlled climate. While the far north of New Zealand is experiencing equatorial warmth, the south, 1600 km away, may be shivering in a blast of cold polar air, and occasionally vice-versa, but here are some of the 'rules' anyway.

The rules

Typically, the west, exposed to the moist westerly winds drumming across the Tasman Sea, is famous for its rain, often in summer, and the east side is correspondingly dry (foehn wind or Chinook). However, when the weather flows in from the south in winter, this feature is often reversed with sun on the West Coast and rain in the east.  A little known fact is Hokitika on the South Island's 'wet' West Coast has a similar number of sun hours as Christchurch on the east. But as Tourists are generally only here in summer they think Hokitika is always wet and people are lunatics to live there.

Temperatures in the mid-20s are the norm in the summer months of January and February in both Islands, although the North is humid and the South drier. Winter snows start arriving from May, bringing day time maximums of only a few degrees Celsius to many of the southern townships.  


So what month should you plan on?

When should you fly down under for your adventure holiday? Each season does bring different elements to your hiking experience and although climate change is said to be adding another level of unpredictability, it's still the old el nino / la nina weather patterns that hold the power here when they awake from their slumber. Hilariously we have had a hiking group enjoy a white Christmas in Fiordland National Park - think about it, it's like a German or a New Yorker building snowmen in late June. Too weird. Below are some expectations you should have for the four seasons.


Spring Hiking in New Zealand

North Island weather: 16-20⁰C (60-68⁰F), 90-120mm of rainfall per month

South Island weather: 13-19⁰C (55-66⁰F), 60-100mm of rainfall per month

As the earth's tilt positions New Zealand towards the sun, the days begin to get a little longer and a little warmer. The country springs to life with a burst of colour from the pink blossom trees filling the streets and local parks, nutrient-rich green grass, clear blue skies and a dusting of powdery snow still coating the mountain peaks from winter.

The warm sun welcomes new life; you don’t need to travel far to get your fix of spring baby lambs and calves frolicking amongst the fields of yellow daffodils.  

Spring is a great time to dust off your hiking boots and head out in to the hills. You will find the tracks a lot quieter as the tourist season hasn’t begun just yet. The sun fills everyone with excitement to explore the outdoors and our guides are well rested and eager to get back out in the wilderness for more adventures.

September - Even though the days are starting to warm up, snow can still be seen on the mountain peaks. Winter sports lovers lap up the last run of the Ski fields as the snow starts to melt away. The last Sunday in September the clocks spring forward gracing us with an extra hour of daylight!

October - We experience warmer and a bit windier days from the west (equinox weather). Alpine flowers reward those willing to hike that little bit further up to the receding winter snow fields.

November - The busy Summer season is just around the corner. Schools and businesses aren’t out just yet so this is a great time to avoid the tourist rush and head out in to the hills. The sun melts away the snow causing river levels to rise and creating powerful waterfalls which are an impressive sight.

Our trip pick in Spring is the Spring Wanderer, be the first to hit the hiking trails before the peak season begins.

Summer Hiking in New Zealand

North Island weather: 20-24⁰C (68-75⁰F), 60-100mm of rainfall per month

South Island weather: 19-23⁰C (66-73⁰F), 35-60mm of rainfall per month

The latter half of summer is the warmest time of the year to go trekking in New Zealand (although not by a huge degree). It is the long summer evenings, particularly in the South Island, that makes hiking so relaxed and enjoyable; With daylight close to 10 pm there is no rush to get there. Life definitely operates at a slower pace in Summer. Once the Christmas rush is over,  locals can relax and enjoy warm nights down at the beach with a picnic dinner.

December is a great time to travel to New Zealand. Locals are on the starting blocks for their main holiday but haven’t escaped the daily grind until after Christmas so beat them to it while the roads and tracks are quiet. School’s out for the Summer from late December to late January. Universities break up from December through to February and most Kiwi’s take their annual leave for 2 to 3 weeks from the 26th December. 

January and February are usually the warmest months of the year and hence the most popular for getting into the New Zealand wilderness. You are guaranteed some settled weather and you will be sharing these lovely long days with kiwis (of the hiker variety) and that’s a great thing - they are pretty welcoming to overseas folk in the backcountry. It's never that mad or busy if you are comparing it to the European Alps in the summer - there are only 4 million of us here in a country the size of the UK with a quarter of it National Parks, so a few famous spots aside, it's all pretty civilised out there. In February school goes back so the pressure goes off a number of “front country” hiking trails and huts. Note there are a bunch of bank holiday weekends in January and February that will make huts pretty busy - keep an eye out for those.

Our trip pick in Summer is the Ultimate North and Ultimate South or if you have 23 days up your sleeve, combine the two for a full Ultimate New Zealand trip. Warm Summer nights are the best time to have your first experience staying in a Kiwi backcountry hut or camping under the stars.

Autumn Hiking in New Zealand

North Island weather: 17-22⁰C (62-71⁰F), 90-130mm of rainfall per month

South Island weather: 13-19⁰C (55-66⁰F), 60-100mm of rainfall per month

Autumn is fantastic and few people realise how settled the weather is this time of the year. Although the sun sets earlier by the day, the warm nights can be enjoyed with shorts and a long sleeved top and most Kiwi’s will be stretching out the use of jandals well in to Autumn. In the north west of the South Island and especially the top of the North Island it is still warm enough to enjoy swimming (the tropical ocean currents are still here). Hiking is phenomenal in Autumn and the most colourful time of year, the trees are coated in rich gold, red and orange tones throughout the country. With less people on the hiking tracks, native birds flutter about the trees and the forest comes alive with bird song.

March is as good as February, sun protection and swimwear are a must have. The nights can cool down later in the month so a warm layer will keep you comfortable after a day of hiking.

April is when we lose an hour of daylight as the clocks fall back on the first Sunday of the month. However, this is still one of the best months in the outdoors with the most reliable weather. Sure, the occasional front rumbles through, and the air is a bit cooler, but you may get a weeks worth of consistent perfect weather. The crisp mornings and bright blue days are a real treat especially in Central Otago and Hawkes Bay. 

By May the first dustings of snow arrive and define the mountain tops. You will generally have the hiking trails to yourself by now, but if you show a little cunning and are flexible you will have a good time. Have some plans for bad weather too though!

Our trip pick in Autumn is the Northern Portion and Southern Slice or combine the two islands on the New Zealand Uncut. In Autumn the famous Tongariro Crossing has less foot traffic and less chance of people photobombing your perfect picture of Mt Doom. Queenstown is the best location to end your trip as this is where you will experience the special golden sunsets amongst the Autumn coloured trees.

Winter Hiking in New Zealand

North Island weather: 11-15⁰C (51-59⁰F), 120-150mm of rainfall per month

South Island weather: 7-12⁰C (44-53⁰F), 70-130mm of rainfall per month

Flexibility is the key to great hiking in the winter. Read the forecasts, catch the weather windows and glean some local knowledge. Zip from west to east and back again as necessary just like the locals do. But most of all be prepared - have some good kit and a tent or shelter to wait out those flooded rivers. New Zealand is blessed with a plethora of choices when it comes to hiking so be adaptable and change your destination to match the weather conditions. The misty mornings and crisp light are a photographer’s delight too - try and keep your camera warm or you will be taking pics of lenses fogging!.

June - the beginning of winter so generally there is less snow. The shorter days can still be warm depending on the el nino / la nina offering. Merino layers and a good windproof jacket are key to comfort during a crisp New Zealand winter. There are some special hiking tracks dotted about the country which reward you with a natural geothermal hot pools to soak in and thaw out your toes.  

July - Most visitors are up in the Ski fields, so if you are out on the trails you can enjoy the snow-capped mountain vistas all to yourself. If you are hiking unguided, be sure to check the weather conditions before you set off, especially in alpine areas.

August - Congratulate yourself for being here when the mountains look their best and the weather is getting better again. Consider Nordic skiing or snow shoeing as an alternative to hiking if there is a lot of snow around.

Our trip pick in Winter is the Winter South Island Adventure and North Island Adventure. If you are new to skiing or snowboarding, now’s your chance to learn on some of the best ski slopes in the world!

No matter which month you choose to go hiking in New Zealand you will get a mix of great weather and bad weather.  Always be prepared for sudden changes in weather and temperature so think carefully about what to take. We provide a packing list for each of our trips. As they say – there is no such thing as poor weather, just poor clothing and equipment. The sun too is a danger, don’t be fooled by the welcome warmth it offers, you can get burnt very easily here. We have exceptionally high UV intensity in New Zealand, partly due to our relatively unpolluted air, partly because we are closer to the sun during the summer than our Northern Hemisphere counterparts in their summer and partly due to the weakening of the UV shield over New Zealand.

Let us help you plan and prepare a hiking experience of a lifetime here in New Zealand.
