Precipitation Levels in January
January is generally a dry month across most of New Zealand, particularly in the South Island, which is often sheltered from the prevailing westerly winds by the mountains. However, the North Island experiences more rainfall, particularly on the west coast. Despite this, New Zealand is known for having unpredictable weather, so it is always a good idea to be prepared for sudden rain showers.
North Island (Auckland, Wellington, Rotorua)
The North Island typically experiences light to moderate rainfall in January. Auckland, Wellington, and Rotorua receive between 50 mm and 100 mm of precipitation on average, with Wellington receiving the least due to its more sheltered location. Rain usually comes in the form of short showers or light, drizzly weather. The North Island’s west coast, particularly places like New Plymouth and Raglan, may experience more rainfall, particularly in the form of afternoon showers or storms.
South Island (Christchurch, Queenstown, Dunedin)
In the South Island, January is generally a dry month, with precipitation levels ranging from 30 mm to 60 mm in cities like Christchurch and Queenstown. These areas tend to have more stable, sunny weather, making it an excellent time for outdoor activities. However, parts of the West Coast, including towns like Franz Josef and Hokitika, experience higher rainfall throughout the year, and January is no exception. These areas can receive up to 150 mm of rain, with occasional storms rolling in from the Tasman Sea.
Mountain and Highland Areas (Southern Alps, Fiordland)
Mountainous regions like the Southern Alps and Fiordland receive higher precipitation levels due to their exposure to prevailing westerly winds. While January is generally dry in these areas, it can still experience rain showers, especially in Fiordland, which can receive between 80 mm and 150 mm of rain. The weather in the mountains can be unpredictable, and visitors should be prepared for sudden changes in weather, including the possibility of heavy rain, even in summer.

Wind Patterns and Atmospheric Pressure
January in New Zealand is characterized by moderate winds, especially along the coast. While it is generally a dry month, occasional weather systems, such as low-pressure systems, may cause localized changes in wind patterns and atmospheric pressure.
Wind Speeds
In coastal cities like Auckland and Wellington, wind speeds during January average 15 km/h to 25 km/h, with occasional gusts during storms or weather fronts. Wellington, being one of the windiest cities in New Zealand, can experience stronger gusts, especially along its coastal areas.

As the country enjoys mostly dry and sunny conditions in January, the atmospheric pressure remains fairly constant. However, sudden weather changes and storms can lead to fluctuations in pressure, particularly in coastal areas where low-pressure systems may occasionally develop.
Considerations for Travelers in January
Traveling to New Zealand in January offers excellent weather conditions for many outdoor activities. However, there are several factors to keep in mind to make the most of your trip:
1. High UV Levels
New Zealand is located closer to the ozone hole, which means the country experiences higher levels of UV radiation, especially in summer. Travelers should take necessary precautions by applying sunscreen, wearing protective clothing, and avoiding prolonged exposure to the sun, particularly between 10 a.m. and 4 p.m.
2. Possible Showers and Sudden Weather Changes
While January is generally dry, weather in New Zealand can change rapidly, especially in the mountains and on the West Coast. It is advisable to bring a light rain jacket or an umbrella, especially if you plan to visit areas like Fiordland, which are more prone to sudden showers.
3. High Tourist Season
January is part of New Zealand’s peak tourist season, so popular destinations like Queenstown, Rotorua, and Auckland can get crowded. If you plan to visit these places, it’s a good idea to book accommodations and activities well in advance. Additionally, be prepared for higher prices, as tourism-related services tend to increase in price during this peak season.
4. Stay Hydrated and Protected
While temperatures are pleasant during January, the sun can be intense in many regions, particularly in the North Island. Be sure to stay hydrated, wear hats, sunglasses, and protective clothing, and use sunscreen to prevent sunburn.
5. Outdoor Activities
January is a great time for outdoor activities, but it’s important to be mindful of the weather and your physical condition. If you’re planning to hike, bike, or engage in adventure sports, make sure to check weather reports and be aware of the conditions in your area. In some regions, such as Fiordland or the Southern Alps, conditions can change quickly, and travelers should be prepared for cooler temperatures or rain, even in summer.
