New Zealand's climate varies from subtropical in the north to temperate in the south, with winter from June to August and summer from December to February. Winter hiking can be treacherous, particularly in South Island's mountains due to snowfall and shorter daylight hours.
The weather in spring (September to November) and fall (March to May) is typically milder, but can still be unpredictable, so appropriate gear is necessary. Spring offers stunning displays of blooming flowers, while fall presents beautiful foliage.
The best time to hike is during the summer, but trails can be crowded. Always check local weather forecasts and the Department of Conservation's website (
https://www.doc.govt.nz/) for trail conditions.
