Wellingtonians can expect a warmer, drier start to winter this year.
NIWA's seasonal climate outlook for May, June and July shows the western half of the North Island is likely to be warmer than average.
NIWA Meteorologist Ben Noll said it means the city may see fewer frosty mornings this winter.
"You could go a week or two without seeing one [a frost]."
Noll said the capital could expect milder conditions overall, with some days reaching a high of around 15C. However, the city will still get the occasional wintry blast.
