SUMMARY FOR THE MONTH OF APRIL, 1929.

The general character of the weather experienced in April over the North Island and the northern and eastern districts of the South Island may be described as dull and moist, with, in most districts, an absence of strong winds. In Westland, Otago, and Southland, on the other hand, it was fine, clear, and pleasant for the greater part of the month.

The total rainfall was below the normal over the South Island except in the north-east portion, and deficiencies were recorded also in the central districts of the North Island. In Marlborough and Nelson provinces the falls considerably exceeded the average, as also was the case in the northern and eastern districts of the North Island.

Although temperatures were slightly below normal there were no extremes, and frosts were few and usually of only slight intensity. As a result, the growth of pasture was remarkable in all districts for the time of the year. The prospects of good supplies of feed in winter are, therefore, everywhere bright. Stock have kept in good condition, but the soft state of the grass, owing to excessive moisture, has prevented the fattening of sheep in some parts of the North Island, and in parts of Hawke’s Bay has caused scouring and liver fluke amongst the hoggets.

A characteristic of the month has been the frequency with which cyclones have controlled the meteorological situation, and the almost total absence of the westerly type of pressure distribution. Two of the cyclones had noteworthy features, and may be briefly described:—

The first, which was the one which caused serious floods in Tasmania about the 5th, moved very slowly in a north-east direction across the Tasman, and by the 8th was centred between Norfolk Island and Cape Maria van Diemen, where it remained stationary for several days. On the 11th it had passed east of Cape Maria van Diemen, and then moved gradually
