The pre-summer stunners continue to shine on the Bay, with Wairoa reaching a record maximum temperature for October since 1991 - just shy of the nation's high, with Kaikoura hitting 32C.
Wairoa recorded a scorching 31C yesterday, while Napier hit a cooler 24C and Hastings reached 28C.
MetService meteorologist Ciaran Doolin said a strong northwesterly flow, particularly in the eastern area of the country, was pushing the temperatures up.
"Its called the Foehn effect," Mr Doolin said.
"When air rises up one side of a mountain, it will lose its moisture and warm dry air comes down the other side."
