New Zealand is in for scorching summer-like conditions next week as Australia ships its hot and humid air over to us, Newshub reveals. “Get ready for some summer-like warmth as we go through the next seven days! It’ll be humid too, particularly in the North Island,” NIWA says. “From Tuesday onward, it will be well into the 20s. The country will probably experience its first 30C readings of the spring season between Thursday-Saturday.” A MetService temperature map shows that roasting hot air will drive up the mercury all around the country.
