Warm summer days are still a few weeks away as the windy spring continues to dominate, WeatherWatch.co.nz says.
Weather analyst Philip Duncan said there would be an increase in windy weather from the south or southwest.
"We aren't going back to the very stormy start of spring but certainly the changeable and windier weather, which is more typical of spring, is making a comeback this week and into the first week of summer."
Mr Duncan said the changeable weather might in fact boost warm weather for some regions.
"Eastern areas of the South Island are likely to reach the mid to late 20s at times, maybe even 30 degrees, however in true spring fashion colder, brief, southerly changes will help balance things out.
