Outlook and outcome – May 2004 to July 2004
As expected rainfall was normal over much of New Zealand, except for above normal rainfall in Bay of Plenty and Gisborne. Higher than normal rainfall occurred in the west of the northern South Island with drier than normal conditions in the east.
Many districts recorded higher temperatures than forecast, due to a higher than normal frequency of northwesterlies, particularly in June. Temperatures were average as expected in some eastern regions.
River-flow conditions were forecast to be below normal in the east of the South Island, and near normal elsewhere. Flows were below normal in Northland and the South Island east coast, and normal to above normal elsewhere.
