It was a frosty morning today with the weather station at the Whangārei Airport recording a cool 3.9C.
This is the equal coldest temperature of the year so far, with the same temperature recorded on June 11.
These mornings are unusually cold, though. The average low for Whangārei in June is 9.3C.
Further up north in Kaitāia it was 4.4C this morning, while Kerikeri and Kaikohe were slightly warmer at 7.3C and 7C respectively.
MetService meteorologist Amy Rossiter says its weather stations tend to be placed close to the coast which has an effect of keeping temperatures milder.
