On Wednesday a front moves through both islands bringing cooler temperatures and showers or rain to most areas. Thursday brings a brief clearance as a ridge moves in then on Friday westerlies build again with another front moving onto the South Island later in the day.

A few observations for the past 4 years. We moved to NW Auckland in 2010. Frosts that year in our valley = 21. in 2011, 12 frosts, in 2012, 6 frosts, last year was 1 and then a partial frost. Jun 2012 – warmest on record i think.  May 2013, warmest on record. Apr 2014, warmest on record.(soon to be followed by May i would think) The climate here is changing – The lack of cold means the wasps and all the nasty critters are not being wiped out over winter. My Braeburn apple tree has blossomed twice since harvest in Feb/Mar. Our winters only require a summer weight duvet, and in summer now, we are hot and humid. So, unfortunately it looks like we will be the Brisbane of NZ in 2030 as someone predicted!
