NOTE.—A cloudy and unsettled month, with moderate northerly winds prevailing. Total bright sunshine 102 hours 52 minutes, 35 per cent. of the possible, and eight sunless days. Hail fell on the 13th; fog occurred on the 25th, and frost was recorded on the grass on ten mornings. Mean earth temperature at 1 ft. was 46·2°, and 49·2° at 3 ft. Mean dew-point, 41·7°; mean elastic force of vapour, 0·264 in.; and mean relative humidity, 78 per cent. of saturation.

SUMMARY FOR THE MONTH OF JULY, 1927.

The total precipitation of the month was above normal over the North Island, with the exception of small areas about Cook Strait and at Kawhia and Gisborne. In the South Island there were considerable local variations in the amounts measured, but Nelson and Marlborough had an excess, and also isolated places on the east coast and in western Otago. Westland, North Canterbury, and most parts of Otago recorded less than the mean. In some districts, notably in the Bay of Plenty and Hawke’s Bay, the excess was considerable.

There were three outstanding storms during the month, which may be briefly described as follows: A cyclone from the north-westward was centred over the Auckland Peninsula on the 1st, and passed off East Cape on the night of the 2nd. On these two days some phenomenal rainfalls occurred in the Gisborne and Hawke’s Bay Districts, resulting in serious floods in the low-lying country. Between the 9th and 14th an intense and extensive westerly low-pressure area dominated, with strong northerly winds, changing to southerlies, about the 13th. Much rain fell during this period and, on the 13th, there were heavy snowfalls in the high country in the South Island and also in the central portion of the North Island. Waiouru recorded a fall of 17 in., and at Taumarunui it was regarded as the heaviest fall since 1918. From the 25th to the close of the month wide and extensive cyclonic disturbances operated between New Zealand and Australia, and conditions were again extremely unsettled, with strong north-east to south-east winds. Although precipitation came mostly in the form of drizzle, some heavy rains were occasionally experienced, particularly in the northern and east coast districts on the 25th and 26th.

In many parts of the North Island the continuous rain accounted for serious floods and landslips which interfered with railway and other traffic.

Fair weather ruled between the 3rd and 8th, and other shorter fair periods were experienced, but usually the duration of sunshine was below the average. Temperatures, however, were about normal and above the mean of the previous month, and generally there was a good growth in vegetation for the time of year.
