Annual Water Temperature Trend

Whangaruru is a coastal area in the Northland Region, centred around Whangaruru Harbour and opening toward the Pacific Ocean. The harbour and surrounding bays are partially sheltered by headlands, which helps moderate wave action compared with fully exposed beaches. Sea temperatures here follow the typical pattern of the upper North Island. In summer, from December to February, water temperatures generally range between 19°C and 22°C, occasionally warming a little more in shallow harbour areas during calm spells. Autumn often remains pleasant at around 18–20°C before gradually cooling. Winter temperatures usually sit between 14°C and 16°C, while spring sees a steady rise from roughly 15°C towards 18°C as settled weather becomes more frequent.
