The month began with a series of small and irregular depressions operating over the Dominion. By the 4th these had
moved off to the eastward, where they increased in depth. This condition persisted practically continuously until the 12th,
there being only slight fluctuations, due to pressure waves moving from the westward. Strong southerly winds prevailed,
and gale force was experienced at times in many places. The 7th was a particularly unpleasant day, snow being very wide-
spread on the high country of both Islands, and extending to the low levels in the South Island. Snow and hail were,
indeed, of frequent occurrence in some part or other of the Dominion throughout this period. On the 10th, Gisborne had
its first fall of snow for many years. Precipitation was heavy in Canterbury and Otago, and there were considerable losses
of lambs.
During the 14th and 15th a rather deep depression moved past the Dominion from the westward, its centre crossing
Foveaux Strait. On the 16th a cyclone developed in the northward extension of this depression, and crossed the Auckland
Peninsula during the night. Between the 14th and the 17th rain was experienced in practically all parts of the country.
The eastern districts of the North Island recorded heavy falls on the 16th and 17th.
The above-mentioned storm passed away gradually, and from the 23rd to the 29th a series of depressions of the westerly
type followed one another across the Tasman Sea and New Zealand. It was during this interval that the west coast of the
South Island received most of its rainfall for the month. The mild temperatures brought by the westerlies were a very
welcome change. The last of this series of depressions passed on the 29th, and was followed by severe southerly gales which
continued until the 1st October. In the North Island and Nelson the 29th was a very bitter day with frequent hail storms,
but on the east coast the 30th and the 1st October were more severe. In addition to the widespread hail storms, there
were heavy snowfalls on the ranges.
