NOTE.--A very dry and sunny month. Total precipitation at Karori Reservoir, near Kelburn, was 87 per cent. below the mean of previous years. Total bright sunshine, 245·1 hours, 64 per cent. of the possible, and no sunless days. There was a slight fog on the morning of the 29th. Mean dew-point, 52·4°; mean vapour pressure, 0·392 in.
SUMMARY FOR THE MONTH OF MARCH, 1930.
March has been an exceptionally dry month. Few places received half the average fall, and no case has yet been reported where the average was reached. North of Otago, the mean deficiency was between 70 and 80 per cent., and it is only in the southern portions of Otago and in Southland that the departures fell to moderate dimensions. Some places, such as Auckland, Oamaru, and Westport, had the lowest rainfall ever recorded in March, while at very many others lower totals had been recorded on two or three occasions only.
As would be expected in view of the dry conditions, there was an unusual amount of sunshine. The highest total recorded is 276·6 hours at Nelson, but New Plymouth had 271·6, Masterton 261·6, Auckland 257·9 (its record for March), Napier 252·0, Hanmer 248·1, and Wellington 245·1 hours.
In spite of the fact that there was so much sunshine, temperatures were again below normal, this being the ninth in a succession of cold months. Frosts have been rather numerous, and on the 27th and the 30th were severe enough to do some damage.
Owing to the heavy rains experienced in December and January and the consequent luxuriant growth of herbage, the dry weather of March did good rather than harm. There was still an ample supply of pasture in most districts at the end of the month, and it was more fattening than at the beginning of the year. Crops of all kinds ripened well, too, and harvesting and picking operations were facilitated. The season so far, therefore, has been a very good one. Rain is now, however, badly wanted, and unless it comes shortly conditions will deteriorate rapidly.
The prevailing weather during the month was of the anticyclonic type with its characteristic clear skies and absence of wind. The anticyclones moved on an unusually far southern course and several of them were very intense.
