Shortest Day Of The Year Could Be The Warmest On Record

Weather watchers were anticipating potentially record-breaking temperatures across the country today, the shortest day of the year.

National Institute of Water and Atmosphere meteorologist Ben Noll said daily temperature records would face a challenge, with many places likely to reach highs more typical of mid-April than late June.

Auckland and Hamilton could break their records of 17.8C, New Plymouth is set to beat its 16.4C high and Nelson its record of 15.5C.

In the east of the South Island, Invercargill (record 14.4C), Dunedin (17.4C) and Christchurch (18.2C) are forecast to close in on record temperatures.

The winter solstice arrives at 10.34am today, when the sun's position reaches its farthest point north of the Equator. Today brings the least daylight of the year.

In Auckland, this equates to nine hours, 37 minutes and 58 seconds, and in Invercargill, eight hours, 35 minutes and 5 seconds worth of daylight.

During the winter solstice there was no sunlight at all south of the Antarctic Circle; conversely, it was the summer solstice in the Northern Hemisphere, when the sun was visible day and night in areas just south of the Arctic Circle.

Many Northern Hemisphere countries consider the summer solstice the official start of summer.

In New Zealand, Australia and South Africa, winter begins on June 1 and ends on August 31, otherwise known as the meteorological winter, combining the months with most similar weather together.

After today, daylight will begin to increase.

Most cities in New Zealand would have two or three minutes more daylight by the end of the month.

By the end of July, the additional daylight would reach nearly 38 minutes in Auckland, 45 minutes in Wellington and 54 minutes in Invercargill.
