MetService has issued heat alerts for both Wānaka and Alexandra for tomorrow.
Heat alerts are triggered when the temperature reaches a certain threshold picked by meteorologists for 46 locations using two decades worth of data.
The MetService initiative aims to reduce health impacts from hot weather for babies and infants, older people, and those with pre-existing medical conditions or on certain medications who are more at risk of extreme heat.
Wānaka is expected to climb to 31C while Alexandra may record temperatures of 32C on Wednesday.
“We advise you to keep hydrated, seek shade, check in with vulnerable people and look after your pets & livestock,” MetService said.
However, MetService meteorologist Mmathapelo Makgabutlane said the warmth would be short-lived as a weather system brings rain from the west in the evening.
“Brief rain spreads up the South Island on Thursday, bringing a cooler day for many. For the rest of the country, Waitangi Day is shaping up to be mostly settled, including in Waitangi itself.”
