Look, we live in a rainforest...so YES it rains in Hokitika, anytime of the year! But funny enough, we have similar sunshine hours to Auckland, Wellington and Christchurch. This is because there is not a lot of "in between" weather in Hokitika. When it rains, it pours and when it's sunny, its beautifully sunny.
Our suggestion is to be prepared and then get out and enjoy it, whatever the weather!
The Truth About Our Rainfall
Even though we hold the record for highest rainfall in New Zealand (14100mm in a year!), the Cropp River where the measurement is taken is 20 kms inland in the mountains. So we are often basking in fine weather even while the weather news is telling us it is raining outside. Go figure.
Our location on Hokitika Beach also means we don't experience extremes in temperature. We are warmed in winter and cooled in summer by the sea's influence. June is actually our driest month so winter is a perfect time to visit. Think fresh snow on Mts Cook (Aoraki) and Tasman, not a cloud in the sky and you can still feel your hands (most of the time!).
