NZ weather summary April 1979
« on: February 17, 2012, 07:23:58 AM »
(Note: The Gazette extract report was published with only the data and weather sequence; the other sections were missing. The summary below is as it appeared in Met. Misc. pub 109 (annual summary), and additional comments are derived from the stats. table.)

April 1979:  Conditions were dry and sunny in many districts east of the main ranges in both islands. In the wettest areas of Auckland, Taranaki, Manawatu and the West Coast; also inland Otago/Southland, the rainfall total was 20-30% above normal. At Christchurch Airport only 11mm was recorded for the month, and this is the lowest for April since the station began in 1944. On the 15th extensive damage was caused by flooding in a shopping complex at Mairangi Bay (Auckland). At Whenuapai more than 64mm was recorded in 48 hours, and 45 mm in 24 hours at Albert Park (Auckland). Parts of Otago and Southland had mean temperatures above normal by 1.0oC and many areas of NZ by 0.5oC. Some east coast districts had above normal sunshine hours. At Christchurch Airport a total of 202 hours made this an April record for this station where sunshine measurements began in 1949. Harvesting, which was delayed by heavy rain in March was completed and stock conditions had improved considerably by the end of the month.

Rainfall: refer to above.

Some monthly totals (mm): Kapiti 137, Stratford Mountain House 600, Fox Glacier 644, Invercargill 138; Waitangi 34, Whakatane 31, Masterton 27, Gisborne 26, Blenheim 18, Ashburton 8, Timaru 8.

Temperatures:  refer to above.

27.8C maximum at Akaroa on the 19th, 0.1C minimum at Waiouru on the 2nd.

Sunshine:   Sunshine totals were near normal over most of the country. They were below by up to 20 hours over most of Northland, and in Nelson, Westland and the Southern Lakes region. Bay of Plenty stations were mostly above by about 20 hours. In the east from Kaikoura to Dunedin surpluses of up to 50 hours were recorded. In this area totals were much higher than in the exceptionally dull March, by over 120 hours at Christchurch. Timaru’s total was almost 3 times the March value.
