A large high is covering New Zealand for the first day of spring on the meteorological calendar with a number of regions enjoying a milder than average afternoon.

Anticyclonic gloom means some western areas will again be cloudy for time, including Auckland. 

But most places will be warmer than usual for this time of the year by this afternoon.

Temperatures are already above average in about two thirds of NZ and even warmer weather is coming. By Friday night high pressure will move in over New Zealand and linger until next Tuesday. As it moves over us it will bring cooler nights with lighter winds but the afternoons will be mild, especially Sunday to Tuesday as sub-tropical winds kick in.

A weak cold front moves into the South Island on Thursday but generally speaking most of the country is enjoying average to warmer than average days this week and by the weekend and into next week things warm up even further.
 
In fact next Monday looks likely to kick off with sub-tropical winds descending across much of the country with a fairly calm and settled star

Sub-tropical warmth to kick off September, also a sub-tropical low to monitor
