Mt Taranaki is one of NZ’s wettest spots, and frequently cops snowfalls. The moisture-laden winds coming in from the Tasman Sea are the climatic culprits as they are swept up to freezing heights by the mountain. Weather on the mountain can be extremely changeable and snow is common even in summer. Ironically, New Plymouth frequently tops the list of most sunshine hours in the North Island, emphasising the changeability of weather in the region.
November to April are the region’s warmer months when temperatures hover around 20°C. From May to August, the temperatures drop to around 5°C to 14°C.
