Nelson, located in the north of the South Island of New Zealand, is distinguished by a mild temperate climate, which many travellers find ideal for outdoor activities. Thanks to its favourable geographical position, extreme temperature fluctuations rarely occur here: there is no exhausting heat in summer, and no severe frosts in winter. This makes the region a comfortable destination for tourism at almost any time of the year.

The summer months (from December to February) delight with pleasant warmth with average maximum temperatures around +20...+21°C, which is excellent for visiting beaches and national parks. Winter (from June to August) is cool here but quite mild: during the day the air usually warms up to +10...+11°C, and night temperatures rarely drop below +4...+5°C. The transitional seasons are characterized by a smooth change in weather without sudden cold snaps.

Precipitation is distributed quite evenly throughout the year, with the number of days with precipitation varying from 9 to 15 per month. The greatest number of rainy days falls on late spring and early summer, however, rains here are often replaced by clear weather. Despite the statistics of wet days, Nelson is historically considered one of the sunniest places in the country, so tourists should expect plenty of light, but keep an umbrella or raincoat handy just in case.

The temperature regime in Nelson is characterized by mildness and the absence of extreme fluctuations, making the city attractive to visit all year round. The warmest period is summer, especially January, when the average daytime temperature reaches a comfortable 21.1°C. Summer weather here is pleasantly warm rather than sweltering, creating ideal conditions for active leisure. Even in the hottest months, nights bring freshness as the temperature drops to 13–14°C.

Winter in this region of New Zealand, falling on June, July, and August, is characterized by cool but not severe weather. The coldest month is July: during the day the air warms up to an average of 10.2°C, and at night the temperature drops to 4.3°C. Although frosts are possible, they are not a constant phenomenon, and winter days often remain comfortable enough for walks if you have warm clothing.

Throughout the year, there is a stable amplitude between day and night temperatures, amounting to approximately 7–8 degrees. This means that even after a sunny spring or autumn day, the evening can be quite brisk. Travellers are advised to take this feature into account and bring layered clothing to easily adapt to temperature changes during the day.

In the city of Nelson, precipitation is distributed throughout the year quite peculiarly: with a comparatively small total volume of moisture, rainy days occur regularly. There is no pronounced season of prolonged downpours here, however, the Southern Hemisphere summer can be called the driest period. January is distinguished by the lowest rainfall (about 2 mm), and February delights travellers with the fewest number of inclement days — on average about 9 per month.

The chance of getting caught in rain increases in spring and early summer. The "wettest" month in terms of precipitation frequency is November, when up to 15 rainy days are recorded. In the period from August to December, the number of days with precipitation holds steady at 14, so an umbrella or a light raincoat will become useful accessories on the trip. At the same time, judging by the small volume of falling moisture (on average 4–5 mm per month), rains here are more often in the nature of light drizzle or short-term showers than strong storms.

In winter (June–August), the weather character remains mild. Although the volume of precipitation in May, July, and August reaches its annual maximum (about 5 mm), these are still very moderate figures. Since the temperature even in the coldest month, July, rarely drops to critical levels, precipitation falls exclusively in the form of rain. Snow is uncharacteristic for the city of Nelson itself, which makes it comfortable to visit all year round.

When packing for Nelson, it is important to remember that the climate here is temperate, but the weather can be quite changeable. In summer (from December to February), the temperature stays at a comfortable level around 17–21°C, so the basis of the wardrobe should be light items: T-shirts, shorts, and trousers made of natural fabrics. However, even in the warm season, evenings can be fresh, so be sure to bring a fleece jacket or jumper. Given that the number of rainy days remains consistently high throughout the year (from 9 to 15 days per month), a light raincoat or compact umbrella will become your indispensable companions.

If your trip is planned for the winter months (from June to August), be prepared for the cool weather: the average daytime temperature is about 8–11°C, and at night it can drop to 4°C. At this time of year, the best strategy is the principle of layering. Thermal underwear, warm jumpers, and a windproof jacket will allow you to easily regulate heat exchange depending on activity and weather whims. Since precipitation is also likely in winter, choose outerwear with water-repellent properties.

Regardless of the season, in New Zealand, sunscreen with a high protection factor, sunglasses, and a hat are mandatory attributes for a tourist due to high solar activity. For long walks around the city and picturesque surroundings, be sure to take comfortable, proven walking shoes or trainers with non-slip soles. Such a set of items will ensure your comfort and allow you to enjoy the journey without being distracted by weather conditions.
