Annual Water Temperature Trend

Whakatāne, on the eastern side of the Bay of Plenty, enjoys a sunny climate and access to both the open Pacific Ocean and the sheltered Whakatāne River mouth. Coastal water temperatures here are relatively mild by New Zealand standards. In summer, particularly from January through March, sea temperatures usually range between 19–22°C, making swimming comfortable for most people without a wetsuit. During spring and autumn, the ocean generally sits around 16–19°C, which is still suitable for a swim, although it can feel cool at first. In winter, temperatures often fall to about 13–15°C, so the water becomes noticeably brisk and more appealing to confident swimmers or surfers in thermal gear.
