Annual Water Temperature Trend

Whakatīwai is a small coastal settlement on the western side of the Firth of Thames in the Waikato Region, facing the sheltered waters of the Pacific Ocean within the Hauraki Gulf system. Because it sits inside the firth rather than on an exposed ocean beach, sea conditions are generally calm. In summer, particularly from January through March, water temperatures usually range between 19 and 22°C. Most locals find this comfortable for swimming on warm, settled days. During autumn, temperatures ease back to around 17 to 20°C. Winter brings cooler readings, typically between 14 and 16°C, while spring sees a gradual rise from roughly 15 up to 18°C as the weather improves. Shallow nearshore areas can warm quickly during sunny spells.
