February 2003 was a month of four quarters with weeks of cool cloudy weather alternating with weeks of warm sunny conditions. Low cloud was recorded at times, as was a downpour on the 14th, nor’west gales on the 19th and 20th and an overnight low of 5°C on the 23rd.

February 2004 was a stormy month, with heavy rain events on the 1st, 14th, 15th, 16th, and 19th. There were gales on several days and a near record-breaking gust of 180 km/h at Mt Kaukau on the 21st. The thunderstorm on the 19th was impressively noisy and lasted for over 2 hours.

February 2005 saw a welcome return to warmer, calmer summer weather. Daily maximums began rising steadily from 23°C on the first, to a welcome 32°C on the 5th, after which they began settling back due to cloudy weather. Several days with mid-20s maximums between the 19th and the 25th helped the month end on a bright note.

February 2006 had 13 days on which strong winds blew – almost double the next windiest February, 2004 – continuing January’s windy trend. Rain rates reached 72 mm/hr during a brief downpour on the 10th but the short nature of the event meant that surface flooding was limited. Whilst the maximum temperature was nearly 5°C lower than the maximum for February 2005, most of the month was pleasantly warm.

February 2007 was a remarkably dry month during which only 12 mm of rain fell on 5 days – a dramatic change from the latter part of 2006 when the region gurgled under its burden of rain. In typical February fashion, the month’s highest temperatures were recorded during the first 10 days of the month, with daily maximums of 25°C or higher on 5 days. The month finished with daily maximums between 21°C and 26°C signalling a gradual transition to autumn.
