New Zealand Weather Summary for 1948
« on: May 21, 2019, 06:06:45 PM »
A Brief Review of 1948.

The annual rainfall was below the average in the Wellington and Hawke's Bay districts and in parts of Northland; also over the South Island with the exception of some districts in Nelson and Marlborough and near the eastern slopes of the Southern Alps. The deficiency was greatest in North Otago and North Canterbury. A few local areas in the North Island had a surplus of 40 per cent. These were located in the Gisborne and Bay of Plenty districts and north of New Plymouth. Annual temperatures were above normal. The departure did not amount to 1° F. in the South Island but was greater than 1° F. over most of the North Inland. A positive departure of almost 2° F. in the Rangitikei district was exceptional. For the most part the duration of bright sunshine was above normal, in particular by more than 200 hours in South Canterbury. Less favoured were western districts between Auckland and Wanganui and Nelson. Napier and Gore had a deficit of some 60 hours.

Seasonal Notes.—Warm, sunny weather prevailed during the first three months of 1948. Following two months of dry weather at the end of 1947, the cumulative effect of low rainfall for five successive months brought about a drought in several parts of the country. The areas chiefly affected were Rangitikei, Manawatu, and North Wairarapa. In the last-named area the rainfall for the period November, 1947, to March, 1918, was the lowest of any five consecutive months for over fifty years. Useful rains in the early part of April provided some relief, and in May rain came in abundance, totals being generally two or three times the average. Towards the middle of the month a storm caused severe flooding and loss of stock in the Gisborne district. Temperatures were generally above average throughout the winter season, and pastures in the drought-affected areas recovered well. July was the mildest of any since 1917, though it was also dull and wet. In August there were many fine, sunny days while in parts of Central Otago there was no rain at all. By the end of the season stock was in excellent condition, the absence of snow or stormy winds being particularly welcome at lambing time. September, October, and November were fairly typical of a normal spring season. There was little settled weather, changeable westerly conditions predominating throughout. A few very wet days occurred in and west of the Southern Alps, and, Subsequently, rivers in Otago and Southland rose temporarily to flood levels. Growth of crops and pastures was good, with dairy production well above average. Very changeable conditions persisted during the first half of December, but a spell of hot, dry weather arrived over the Christmas period. The month as a whole was warmer and drier than usual, especially in eastern districts.

One of the sunniest years in the record, subject to the usual caveats. Gisborne and Napier had very high sunshine totals in December. Wellington recorded its warmest ever December day. The 1947-49 polio epidemic affected the start of schooling in 1948, including mine.

The annual average sunshine for Gisborne and Napier was 2300 ans 2355 hours respectively, until 1994 where Napier had 2445 hours of sunshine.

For 1948 I see (from CliFlo data which in some cases updated some older numbers)  2351 hours for Gisborne, and 2361 for Napier. In 1994, Napier had 2588 hours.

In earlier days I compiled the monthly sunshine data for NZ sites by laborious manual means. Later on I got annual summaries from NIWA - but paid for them. When NIWA was forced to supply the data for free in 2007 or thereabouts I downloaded all of the monthly sunshine data.
