When's the best time to visit Nelson?
One of the most popular times to visit Nelson is in summer as the weather is usually at its best (warm but not too hot) and there are 8+ hours of sunshine per day to enjoy the great outdoors. While the whole season is generally a great time to travel, January and February are the best months out of the three as December can experience quite a bit of rainfall. If you prefer to holiday without the chance of rain, traveling in January, July, and November are the safest bets.
The summer months are the perfect time to explore the various national parks and beaches Nelson has to offer, however, it is peak season during this time so expect crowds of travelers wherever you go. The UV rays are also at their highest in summer with January recording a level of 11 per day so make sure you're being sun-smart and applying sunscreen whenever you go outside.
If you want to avoid the crowds, try traveling in fall (March, April, and May) or even in October as the weather will still be warm and rainfall minimal.
