If you thought January was particularly dry this year, you were right.

Data from Niwa shows that parts of the southern regions recorded their driest January on record.

Meteorologist Seth Carrier said monthly rainfall totals were below normal across a large majority of New Zealand, including almost all of the North Island, as well as the upper, western and lower parts of New Zealand. South Island.

Wanaka recorded just 3mm of rain in January, its lowest total since records began in 1927.

Other places with their lowest rainfall in January were Manapouri (West Arm Jetty) (25mm), Franz Josef (42mm) and Milford Sound (48mm).

Mr Carrier said the early days of 2022 had also been marked by warm temperatures across much of New Zealand with many places above 30 degrees Celsius.

“This was caused by a combination of a warm air mass overhead, abundant sunshine due to high pressure and a northeasterly wind flow.

“Generally calm weather in January meant continued marine heatwave conditions in the waters around New Zealand – particularly at the start of the month, when sea temperatures were 2 to 4 degrees Celsius above from the average.

Several near-record average maximum air temperatures were also recorded in the south.

Manapouri (West Arm Jetty) recorded its second highest mean air temperature in January at 22.4 degC; Cromwell recorded its third highest with 27.9 degC and Wanaka recorded its fourth highest with 26.8 degC.

January’s highest temperature was 34.7 degC, observed at Lake Karapiro (Waikato) on January 4, and the lowest temperature was 0.4 degC, observed at Invercargill on January 28.
