NOTES ON THE WEATHER FOR OCTOBER, 1929.

The month has been notable for the exceptionally dry conditions experienced over nearly the whole of the Dominion. A few places, from Auckland northwards, had an excess, and in the East Cape, Gisborne, and Napier districts, more especially the coastal portions, the average was also exceeded, but elsewhere in the North Island and the whole of the South Island recorded below normal falls. Oamaru had only five points, which is the lowest month’s total ever recorded there. In the East Coast provinces of the South Island and Otago generally the deficiencies were considerable, and this, combined with the cold temperatures experienced, severely retarded the growth of vegetation. Throughout the country districts in the South Island the backwardness of the season was clearly evident, and feed, in some cases on well stocked land, was rather scarce. In the North Island there were more days on which rain fell, and the scarcity of feed was not so apparent, so that usually stock kept in good condition, although feed was rather short for cattle.

Temperatures were, on the whole, below average, and there were rather more frosts than is usual at this period, those on the 15th and 25th doing some damage to early-sown crops.

From the 1st to the 7th, and again from the 10th to the 17th, fine weather was experienced practically generally under the influence of well developed anticyclones. The remainder of the month, however, except for occasional brief intervals, was subject to changeable and unsettled conditions.

On the 8th, the front of a vigorous depression moved on to southern New Zealand, while a cyclone was passing to the northward. Strong east winds prevailed at this time north of Auckland, with some rain. Unsettled conditions gradually became general with the advance of the southern depression, and on the 9th rain fell in most districts, but in the South Island the falls were only light and scattered. Motu, in the Gisborne district, had as much as 421 points on the 9th. The passage eastwards of this depression brought a cool southerly change during the night of the 10th.
