New Zealand Weather Summary for 1930
« on: June 06, 2019, 05:57:02 PM »
BRIEF SUMMARY OF THE WEATHER FOR 1930.

January, in addition to being very stormy, was the next wettest January to the record one of 1923. Rainfall was almost everywhere above normal.

February provided a marked contrast with January as regards precipitation. Most of the Dominion experienced a deficiency, Hawke's Bay, Wellington, and the South Island having only about half the normal totals. Heavy rains were, however, experienced between Poverty Bay and East Cape.

March was even drier than February, the North Island suffering on this occasion more than the South. Much less than half the average rainfall was recorded. The fine weather enabled harvesting operations to be carried out under favourable conditions.

Over most of the Dominion the dry conditions continued throughout April. Frosts were rather numerous. Severe thunderstorms occurred on the 9th in the Motueka and Moutere districts, accompanied by very heavy rain. In parts of the Moutere hills record floods were experienced.

The dry spell was broken in the second half of May, which was stormy and showery. The total rainfall for the month was still, however, almost everywhere below the average.

In June the weather was at times stormy. Frosts were numerous and rather severe. Rainfall remained below normal, except in the far North and South. Nelson, Marlborough, and the interior of the South Island continued to suffer from a severe shortage.

July was very cold and stormy, with frequent hail, and, in the ranges, snowstorms. Nelson, Marlborough, and the interior of the South Island continued to experience very dry conditions. On the 5th and 6th there was flooding in the Auckland Province, especially the southern part, a series of cyclones being responsible for the rainfall.

Rain was more plentiful in August, the North Island and the east coast of the South Island having more than the normal. The second half of the month, also, was mild, and growth commenced in pastures. Floods occurred in the Heathcote River at Christchurch at the end of the first week of the month following continued rain.

September saw a return to cold and stormy weather. A considerable mortality resulted amongst new-born lambs, and the growth of vegetation was retarded. Gisborne had the first fall of snow for many years. Better rainfalls were experienced in eastern districts.

In October the weather remained cold and stormy and the season backward. Precipitation was below normal in most districts. Severe south-westerly gales on the 25th did considerable damage in the locality of Auckland.

In November there was much stormy weather of the westerly type. Rainfall was above or below normal according to whether the aspect was westerly or easterly. Severe floods occurred on the 26th in the Hutt Valley and at Otaki. For the third month in succession, mean temperatures were the lowest experienced in the respective months since the taking of records commenced.

Rainfall was much below normal in December, and temperatures still low at most stations.

The Year 1930 was remarkable for being one of the coldest and also one of the driest on record. 1902 was colder and 1884 and 1912 were about equally cold, but in no other years, since 1864 at least, have temperatures been so low. For the Dominion as a whole, possibly no year has been as dry as 1930. In the greater part of Canterbury and Otago, however, precipitation was approximately normal, while in the North Island 1914 and 1919 were rather drier. It was in the western half of the South Island that the deficiencies in 1930 were most marked.

As would be expected from the foregoing there was a relative absence of westerly and a prevalence of southerly winds. Snow and hail storms were frequent, though not especially heavy.

In spite of the severe conditions, the year was, in general, a good one for stock and crops. In Hawke's Bay the cold and dry winter and spring were responsible for some heavy losses of sheep.

An exceptionally cold year, but with lighter winds than normal and a prolonged run of anticyclonic conditions in autumn. For the west of the South Island and much of the hinterland it was the driest year on record, or close to that. Sunnier than the long term average in most areas.
