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.
