*** Forecast - Our water temperature forecast

Actual near-shore water temperatures in Kūaotunu West can vary by several degrees from the values shown, particularly after heavy rain, strong southerlies, or prolonged windy conditions. Certain wind patterns can trigger upwelling, where cooler, deeper water is pushed to the surface and replaces the warmer top layer, leading to noticeable short-term changes in water temperature.

Our water temperature forecast is produced using a proprietary mathematical model that combines real-time measurements with long-term historical patterns, local weather conditions, wind strength and direction, and air temperature specific to each coastal region. To improve accuracy, we cross-check data from nearby locations and use multiple sources, including offshore buoys, satellite-based sea surface maps, and observations provided by local authorities.

Annual Water Temperature Trend

Kūaotunu West is a quiet coastal area on the inner side of the Coromandel Peninsula in the Waikato Region, looking out over sheltered waters connected to the Pacific Ocean through the Hauraki Gulf. Because it sits on the western, more protected side of the peninsula, sea conditions are often calmer than on the exposed east coast beaches. In summer, particularly from January through March, water temperatures generally 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 season progresses. Shallow inshore areas can warm quickly in sunny weather.
