New Zealand climate in June 2006

Temperature (click to enlarge).

June 2006 was the coldest June since 1972, with much of the country recording temperatures of more than 2.0 °C below average. Snow fell to depths of 15-90 cm in Canterbury, and also closed roads in the North Island. There were more frosts than usual across much of the country.

Precipitation was about 200% of normal in South Canterbury, but about half normal in much of Bay of Plenty. June was much sunnier than normal in all western and southern regions.

Soils at or above field capacity

Along the east coast, soils were mostly at or above field capacity at the end of June, and mostly at field capacity elsewhere. Soil conditions in Otago were wetter than at the end of June last year.

 

High river flows in the east

High stream flows occurred in eastern regions of both islands and in some rivers in Waikato, Bay of Plenty, and Buller. Near normal stream flows occurred in most other rivers, but below normal flows occurred in some rivers, particularly in the Wellington/Kapiti Coast region.

Rainfall

Rainfall was normal or above in most districts, and higher than predicted in the east of the country. Predictions of drier than normal conditions in parts of the west and south of the country were correct.

Air temperature

Air temperatures were near average, and lower than expected, over much of New Zealand.

River flows

Stream flows were above normal in the north and east of both islands, and near normal in most other locations. Below normal flows occurred in the far southwest of the South Island.


The three outcome maps give the tercile rankings of the rainfall totals, mean air temperatures, and mean river flows that eventuated from April to June, in comparison with the forecast conditions.

As an approximate guide, middle tercile rainfalls typically range from 80 to 115% of the historical normal, and middle tercile temperatures range about the average by plus or minus 0.5 °C.
