Hotter and wetter forecast from Niwa
Tairawhiti can expect above average temperatures with a good chance of above average rainfall as well over the next three months according to Niwa's three month climate outlook report.
Niwa points to higher than normal pressure and drier conditions likely, with moist, sub-tropical disturbances expected to reach the country occasionally, particularly the North Island and northern South Island.
“These systems can cause areas of heavy rainfall and flooding in the December-February period,” the report states.
“Marine heatwave conditions formed near the northern North Island and northern Tasman Sea during November.
“Unusually warm seas in other coastal regions may develop into a marine heatwave over summer.
“Air temperatures are very likely to be above average in all regions of the country with elevated humidity levels from time to time, particularly in the North Island.”
The Niwa report said there was a 75 percent chance Gisborne, Hawke's Bay and the Wairarapa would have above average temperatures, so very likely it will be warmer than usual.
“There is a 40 percent chance rainfall totals will be above normal, 35 percent chance they will be near normal.
“Episodes of heavy rainfall are possible through the season in those regions, which could increase the chance for flooding events.”
