June 2005

Rainfall: Extremely dry in the east of the South Island, above normal in Hawke’s Bay and Southland

Sunshine: Well above average in the northern North Island, and the south and west of the South Island

Temperature: Below average in the south and east of the South Island, near normal in much of the North Island

June for many was drier and sunnier than normal. Rainfall was well below normal in Marlborough, Canterbury, and parts of Otago, where many locations recorded totals ranging from 5 to 15 mm, some sites experiencing their driest June since the mid 1980s. Timaru Airport recorded a total of only 4 mm (11 percent of normal). In contrast, above average rainfall occurred in Hawke’s Bay and Southland. It was very sunny for June in northern regions of the North Island, and also the south and west of the South Island, Dunedin having its sunniest June in more than 50 years of measurement. The national average temperature for June was 8.3 °C. This was 0.2 °C below normal, and the lowest for June in a decade (7.8 °C in 1996). It was also the first June since 1998 which was not warmer than normal. Mean temperatures were near average throughout much of the North Island and the north of the South Island. They were below average in Canterbury, Southland, and Otago. During June, anticyclones ('highs') were often centred west of the South Island. These resulted in above average pressures over New Zealand, with more frequent cool southerlies than average, especially over the North Island.
