"There's a definite autumnal tinge to the air with the cold and it's down to about 12C at night after very hot days."
At Auckland Airport yesterday's peak daytime temperature was 22C, cooled by clouds and a 20km/h wind.
But on the sheltered side of the region, sunburn was the biggest worry for parents of the 500 who took part in the annual Children's Day at Browns Bay Village Green. East Coast Bays community co-ordinator Sally Cargill said the slippery water slides were a favourite when kids were let loose to chase bubbles and play with lots of toys.
MetService meteorologist Mark Todd said Auckland and the rest of the upper North Island could expect more temperatures in the low 20s with fresh southwesterly breezes during the week.
"Temperatures are not falling substantially in these areas but those stronger wind speeds will make it feel a tad cooler," he said.
The wind was just "a taste of autumn" compared with a gale-force southerly expected in Gisborne, Hawkes Bay and the Wairarapa.
Southerly gales would lash Otago and Canterbury, spreading north up the east coast before easing on Wednesday morning. MetService also issued a snow warning above 800m on Milford Rd in Central Otago.
