On the 16th a belt of high pressure was advancing on to the north-west Tasman Sea, on the 22nd it crossed northern New Zealand, and by the end of the month the anticyclonic centre was not far distant to the north-east.
Hence, during this period, there was a predominance of winds from the westerly quarter, with directions turning temporarily south of west after the passage of troughs which arrived in the far south on the 19th, 23rd, and late on the 27th. There was comparatively little rain, the weather being mainly fair to cloudy, but the last of these disturbances was connected with vigorous depressions centred near Chatham and Lord Howe Islands. It produced heavy rain in the northern portion of the South Island, and by the close of the month general rain was setting in over the North Island.
