Annual Water Temperature Trend

Matakana Island sits across the harbour entrance from Tauranga and stretches along the Pacific coast in the Bay of Plenty. Because it faces the open ocean, water temperatures follow a similar pattern to the wider region. In summer, particularly from January through March, sea temperatures usually range between 19–22°C. At this time of year, swimming is generally comfortable for most people, especially on calm, sunny days with light winds. During spring and autumn, the water typically sits around 16–19°C, still suitable for a swim, though it can feel cool when you first step in. In winter, temperatures often drop to about 13–15°C, making conditions noticeably brisk and more appealing to confident swimmers or those wearing wetsuits.
