Annual Water Temperature Trend

Umupuia Beach is a quiet stretch of coastline in the eastern part of the Auckland Region, looking out over the Hauraki Gulf toward the Pacific Ocean. The beach is relatively sheltered compared with fully exposed ocean shores, which helps create steadier and often slightly warmer surface conditions during calm weather. In summer, especially from January to March, water temperatures generally range between 19 and 22°C, making it comfortable for swimming on a warm day. Through autumn, the sea cools gradually to around 17 to 20°C. Winter temperatures usually sit between 14 and 16°C, while spring sees a rise from roughly 15 up to 18°C as the season progresses. Shallow areas near the shore can warm quickly during sunny spells.
