New Zealand Climate

Dry and cool

April continued the generally cold dry theme of March. Rainfall was well below average over much of the northern half of the North Island until almost the end of the month. Less than 50% of average April rain fell in Northland, Auckland, much of Waikato, the central North Island Plateau, Westland, Fiordland, south Canterbury, and the Southern Lakes district. In contrast, rainfall was well above average in parts of Bay of Plenty and Southland.

Mean temperatures were well below average throughout much of New Zealand, especially in King Country, Wairarapa, and eastern and southern parts of the South Island.
