SUMMARY FOR THE MONTH OF SEPTEMBER, 1916.

The weather during September was on the whole mild and spring-like, and, except in the southernmost districts, precipitation was everywhere below the average.

There were three noteworthy atmospheric depressions accounting for short periods of disturbed weather, and these may be briefly described.

Although an anti-cyclone ruled in the north between the 1st and the 11th, relatively low pressure was in evidence during this period in the southern districts, and on the 6th and 7th this depression intensified considerably over the South Island, being responsible for somewhat boisterous conditions in and southward of Cook Strait. Some heavy rainfalls occurred about this time in Westland and Otago. Bluff recorded 5·57 in. for twenty-four hours up to 9 a.m. on the 7th, and some of the rivers in Otago rose to flood-level.

Between the 13th and 15th the passage of an intense Antarctic low-pressure area caused very stormy weather, heavy westerly gales prevailing on the 13th, changing to south-westerly on the 14th. Considerable rain fell, and on the 15th snow was also reported in various districts in the South and inland on the higher levels in the North Island.

The third unsettled period—viz., between the 26th and the end of the month—was the result of a disturbance located on the Tasman Sea, the centre of which passed down the west coast on the 28th and 29th. Dull skies and much mist and fog were experienced, with rain in scattered districts, but in Taranaki heavy rain fell on the two latter days.

A week of very fine weather was experienced from the 18th to the 25th, when a decided anti-cyclone held sway which, on the 21st, was remarkable for a central isobar of nearly 30·8 in. about Cook Strait.
