SUMMARY FOR THE MONTH OF OCTOBER, 1930.

General.—The past month has been, for the country as a whole, the coldest October experienced in New Zealand since the accurate recording of temperatures commenced. From all parts of the country come accounts of the coldness and backwardness of the season. October is the month in which pastures usually show rapid growth after the semi-dormant winter period, but this year the growth has been very poor in most districts. The stormy weather experienced during the month added to its severity. The adverse conditions as regards growth of vegetation have been accentuated, so far as most districts are concerned, also, by the lack of sufficient precipitation. In consequence, stock are generally in a somewhat backward condition. Frosts occurred on several days over large parts of the Dominion, and, in some cases, they were severe. A certain amount of damage was consequently caused to orchards and small crops, but generally speaking it does not appear to have been severe.

Rainfall.—Precipitation was greater than the average on the West Coast of the South Island, over most of Otago, and in scattered parts of the western districts of the North Island, especially around Auckland. Elsewhere there was a deficiency. Even in Central Otago some parts had less than the average amount. In North Auckland, and the East Cape, Gisborne, Hawke’s Bay, and Wairarapa districts, around Wellington, and in Nelson, Marlborough, and North Canterbury, the month was a very dry one.

Snow fell on the ranges on the 14th, 17th to 19th, 22nd, 23rd, and 25th. The falls which occurred at various places on the 17th, 18th, and 19th were the heaviest, and extended to low levels in parts of the South Island. Hailstorms were frequent at many places.

Temperature.—As has been mentioned, temperatures were generally lower than had been recorded hitherto in New Zealand. At Napier, Hokitika, and Dunedin, one slightly colder October has been experienced, but at all other stations this year’s was the coldest.

It is noteworthy that the present spell of abnormally cold weather has lasted, with only short breaks, over most of the country since June, 1929.
