Wind pattern affects the sea surface temperature around the New Zealand coast

“Persistent northeast sector winds are forecast to change the sea surface temperatures around New Zealand this coming week,” says MetOcean Solutions senior oceanographer, Dr Rafael Soutelino.

“Gisborne, Coromandel, and parts of Northland will have the surface water transported offshore, and replaced by cooler waters from depths,” explains Rafael. “Indeed a 3 degree drop to a chilly 16°C is expected in Gisborne by 19 January. Meanwhile, on the West Coast we will see the opposite effect, with further warming of the water near the shore. Raglan may see temperatures rising again to as high as 23°C in the next week. That’s 3 degrees above the average for January.”

“Other places like Bay of Plenty will have slight onshore flows, which will maintain the warm coastal waters,” he adds.
