Seasonal Climate Outlook: November 2005 January 2006
DRIER SOILS AND LOWER STREAMFLOWS LIKELY IN THE SOUTH ISLAND
Climate and Oceans: More anticyclonic southwesterly airflow over the North Island, and anticyclones to the south of New
Zealand are expected, with sea temperatures remaining slightly warmer than normal. The tropical Pacific is presently in
a neutral state (no El Niño or La Niña). Conditions are likely to stay in the neutral range into autumn.
Temperature: Air temperatures are expected to be average or above average in all regions of New Zealand.
Rainfall, Soil Moisture and Stream flows: Rainfalls are likely to be normal or below normal in the east of the North
Island, and normal in all other districts. Normal soil moisture and streamflows are expected in the North Island, but
general dry conditions are likely in the South Island.
