Annual Water Temperature Trend

Mokau is a small coastal settlement near the southern boundary of the Waikato Region, where the Mokau River meets the Tasman Sea. Although sometimes associated with the broader Pacific, this stretch of coastline faces the Tasman and is known for its rugged, exposed character. In summer, particularly from January through March, water temperatures generally range between 18 and 21°C. Most locals find this comfortable enough for a swim on warm, settled days, though the open coast and steady breeze can make the water feel cooler. During autumn, temperatures ease back to around 16 to 19°C. Winter brings cooler readings, typically between 13 and 15°C, while spring sees a gradual rise from roughly 14 up to 17°C as the season progresses. River flow can slightly influence temperatures near the mouth.
