*** Forecast - Our water temperature forecast
Actual near-shore water temperatures in Narrow Neck Beach 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 Overview by Month
Monthly Water Temp Ranges
Annual Water Temperature Trend
Narrow Neck Beach is located on Auckland’s North Shore, facing the Hauraki Gulf and the Pacific Ocean. The beach sits in a relatively sheltered position, which helps create calmer sea conditions compared with more exposed parts of the coastline. In summer, particularly from January through March, water temperatures generally 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 ease back to around 17 to 20°C. Winter sees cooler water, typically between 14 and 16°C, while spring brings a gradual rise from roughly 15 up to 18°C. Shallow areas close to shore can warm quickly during sunny weather.
