Kiwis in the upper North Island can expect uncomfortable nights tossing back the covers with humid conditions forecast this week.
MetService expects minimum temperatures in Auckland and Northland to stay above 20C through to Saturday, thanks to a warm humid air mass holding steady at the top of the country.
Areas including Kaitāia, Dargaville and Whangārei are not expected to dip below 23C almost all week.
Auckland would be much the same at 21-22C. From Thursday, Hamilton and Rotorua would not see temperatures fall below 20C.
