After days of warm weather, Christchurch is now officially in a heat wave, but forecasters warn it may not last.
Thermometers in the city reached 26 degrees Celsius on Tuesday, after four consecutive days of temperatures well above the 19 ° C average in November.
A heat wave is classified in five days in a row by temperatures 5 ° C above average, said MetService meteorologist Tahlia Crabtree, which Christchurch has now experienced.
Christchurch met the criteria when the city’s airport weather station reached 25 ° C just after 1.30 p.m. It peaked at 26.1 ° C around 6 p.m.

“There will be a shift to the south, bringing temperatures back to a more average range,” Crabtree said.

In late October, Niwa confirmed the arrival of La Niña weather conditions, which heralded a good chance of a dry November for many areas.
In her climate update for the three months from November to January, Niwa said she had high confidence that temperatures would be warmer than usual across the country.
La Niña is typically associated with unusually warm Tasman Sea temperatures in late spring and summer, which can have a profound impact on air temperature above land.
