Dunedin has experienced 17 days of southerly weather in the past seven weeks, of which 13 have been wet, but Wellington has been the wettest of all four main centres, the MetService says.
Temperatures throughout New Zealand took a "sharp dive" into winter-like values between May 1 and June 21 but were now levelling out, MetService weather ambassador Bob McDavitt said.
Dunedin came second of the four main centres with its more than a fortnight of southerly weather. Last year, the city only had eight such days, of which four were wet.
However, it was Wellington which had been hit by a sustained southerly assault, experiencing 27 days of southerlies, of which 16 were wet. It compared with last year's 20, of which 13 were wet.
Christchurch and Auckland were equal with 13 days of southerlies - 12 wet in Christchurch and 9 in Auckland.
It meant the last dry weekend in Wellington was May 2-3, in Christchurch and Dunedin it was June 13-14 and in Auckland it was dry last weekend.
Despite these cool conditions, the coldest time of year was still likely to be between mid-July and early August, as usual.
