Annual Water Temperature Trend

Waiwera is a small coastal settlement north of Auckland, set along the edge of the Hauraki Gulf and the Pacific Ocean. The beach sits in a relatively sheltered position, which helps keep sea conditions calmer than on exposed ocean shores. In summer, particularly from January through March, water temperatures typically range between 19 and 22°C. At these levels, most locals find the sea comfortable for swimming, especially on warm, settled days. During autumn, temperatures gradually ease back to around 17 to 20°C. Winter brings cooler conditions, usually between 14 and 16°C, while spring sees a steady rise from roughly 15 up to 18°C as the season progresses. Shallow nearshore waters can warm quickly during sunny weather.
