Annual Water Temperature Trend

Lake Ferry is a small coastal settlement at the southern end of the Wairarapa in the Wellington Region, where Lake Onoke meets the Pacific Ocean. Sea temperatures here reflect the cooler conditions typical of the lower North Island. In winter, from June to August, the ocean generally ranges between 10–13°C, which feels very cold and is usually only comfortable for surfers or swimmers wearing full wetsuits. Through spring, temperatures lift gradually to around 13–15°C. Summer, from December to March, brings the mildest conditions, with sea temperatures commonly sitting between 16–19°C during settled spells. Early autumn can still see the water around 15–17°C before it cools again.
