SUMMARY FOR THE MONTH OF AUGUST, 1930.

Meteorologically, August in New Zealand is generally considered to be the last of the winter months, but the one just passed has been characterized by distinctly spring-like weather, more especially during the latter half. Temperatures were cold in the early part of the month, when some rather severe frosts occurred in places most subject to them, but, on the whole, conditions were mild for the time of the year. Rainfall exceeded the normal in nearly all parts of the North Island. At a few places in the Auckland Province there was, however, a deficiency. In the South Island, the totals were above normal in the eastern portion from Marlborough to Dunedin, while in all the western half and the greater portion of Otago and Southland they were below. At Nelson City the amount of rain recorded during the past three months has been the lowest for this period since records were commenced in 1883. Owing to an almost continued low rainfall since January, the subsoil in Central Otago has become dry for a considerable depth.

The mild temperatures and the ample rainfall induced a marked growth in pastures in most districts. Compared with the corresponding time last year, the season is in this respect further advanced. Consequently, stock generally are in good condition, and at the close of the month the prospects for the lambing season and for dairying appeared excellent.

The finest weather occurred between the 13th and 23rd, the only interruption being due to the passage of a shallow cyclone over the South Island on the night of the 16th and during the 17th, when fairly general but light rain fell.

The most notable pressure disturbance affecting the Dominion during the month was an intense and extensive cyclone which, advancing over the northern Tasman Sea on the 3rd, moved gradually on to New Zealand. Its central portion crossed the Cook Strait region during the night of the 6th, and barometer readings were very low while it was passing. On the morning of the 6th Chatham Island reported a pressure of 28·90 in. General rains occurred during the 4th and 5th, with many
