NOTE.—A pleasant autumn month, with sunshine well above the average and temperatures below normal. The rainfall was 3 per cent. below the mean of Karori Reservoir, near Kelburn. Total bright sunshine, 166·3 hours, 54 per cent. of the possible, and three sunless days. A frost occurred on the morning of the 18th. Hail fell on the 27th, lightning was seen on the 9th, and fog was in evidence on ten days. Mean dew-point, 45°; and mean vapour pressure, 0·298 in.

SUMMARY FOR THE MONTH OF MAY, 1929.

May was a very dry month over the whole of the South Island and the greater portion of the North Island. The only areas where the total rainfall exceeded the average were the Auckland Peninsula and most of the Gisborne and Hawke’s Bay districts. Many places in the South Island experienced the lowest May rainfall since records have been kept. Although temperatures, on the whole, were lower than usual, there was an absence of strong wind, except for short periods, and this, combined with the frequency of sunny days, was conducive to an excellent growth of pasture for this time of the year. The result is that a plentiful supply of winter feed is practically assured. Stock have generally maintained their good condition, but in parts of Hawke’s Bay and the central portion of the North Island lambs and hoggets have not thrived as well as could be wished.

The main meteorological feature of the month has again been a relative absence of westerly winds owing to pressure systems of the cyclonic type having been most prominent. The only depression of the westerly type of any importance experienced was one which prevailed between the 8th and 10th, and the greater part of the rainfall registered in Westland was associated with this disturbance.

There were a number of small cyclones which, in most cases, passed across northern New Zealand, and brought rain mainly to the northern and east coast provinces of the North Island.

The most notable storm was a cyclone which appeared first on the 11th as a small centre to the north-west of Cape Maria van Diemen. Gradually increasing in extent and intensity as it moved southwards, it affected all parts of the Dominion, rain being general between the 14th and 16th. From Marlborough northwards stormy conditions prevailed, with strong south-east to south winds, which in some places reached gale force. Very heavy rains fell in the east coast
