SUMMARY FOR THE MONTH OF JANUARY.
The North Auckland district and the east coast of the North Island experienced a rainfall in excess of the average for the month; but in almost every other part of the Dominion the total was below.
The chief cause of the abundant falls in the North were two subtropical depressions, one which passed off East Cape about the 3rd and 4th, and a prolonged one which ruled in the North from the 27th to the close of the month.
A small “low” off the east coast of the North Island caused severe thunderstorms in the vicinity of Cook Strait on the night of the 8th.
On the 21st some local thunderstorms, accompanied with heavy downpours in the Tokomaru Bay district, caused serious floods in many of the rivers and creeks. The rainfall in many cases was phenomenal, and hitherto unprecedented in New Zealand.
The only other disturbance of note was a moderate westerly low-pressure area ruling between the 13th and 17th, which brought some rain, more especially in the western districts.
The weather on the whole was fine and seasonable, with occasionally very high temperatures ruling, particularly during the last week, when a persistent high-pressure system was centred in the region of the Chatham Islands.
