Annual Water Temperature Trend

Waitakere, on Auckland’s rugged west coast, is known for its dramatic black-sand beaches, coastal forest and surf-exposed shoreline. The water temperatures around Waitakere are typical of the upper North Island’s Tasman Sea exposure and vary through the year. In summer, sea temperatures commonly reach about 18–22 °C, offering the warmest swimming conditions. During autumn the water cools to roughly 15–19 °C as spring storms ease and the ocean begins to lose heat. Winter brings the coldest conditions, with averages near 12–15 °C along the exposed beaches, while spring sees a gradual rise to around 14–18 °C as the air and sea temperatures recover.
