"In behind the front it's only slightly cooler."
Tuesday was going to be warm and fine with the hottest place in Northland expected to be Kerikeri and Paihia on 25C.
Yesterday's heat comes after it was announced last week Northland was the hottest region in the country last year, for the fifth year running.
All of Northland's six weather stations featured in the top 15 hot spots, with Whangarei leading with a mean average temperature of 16.9C, recorded at Whangarei Airport.
This was Whangarei's second-highest reading since 1967. With the weather data collected at the airport, the thermometer would have been up to 4C higher inland.
