The graphs below have averages based on my data from the past 10 years.

This graph shows 2017 and 2018 had above average rainfall. 2015 and 2016 have had below average rainfall. 2019 is tracking below average at the end of November and is within 3mm of 2016 total at the same time.
2000 to 2019.
Temperature
This graph shows just how warm February 2016, December 2017 and January 2018 and 2019, were. Now added November 2019 as warm as an average December. NIWA stated there is more hot weather coming in December so Dec 2017 could have a rival.

November 2017 was the least windy November I've recorded in 18 years of records. Dec 2017 more windy than the past 2 years. Below average wind run for August, September and October 2019.
