If the extra blankets are still out and the heaters are still on, we have El Nino to blame for keeping Northland's temperatures cooler than average this springtime.
The complex climate condition, which affects the equatorial Pacific region every few years, will also result in summer in the region being cooler than last year and drier.
MetService meteorologist Georgina Griffiths told the Advocate that El Nino was already dropping temperatures by at least half a degree compared with the usual figures for this time of year.
"Before Christmas will be cooler than usual, as will the lead up from September to November. It's about a half a degree cooler," she said.
Top temperatures were averaging at 17C across Northland this week, with average overnight lows of 9C.
