New Zealand climate in June
June brought lower than normal rainfall in Bay of Plenty, and parts of central New Zealand. More southwesterlies than usual in June meant cold conditions predominated over the South Island. The average temperature for New Zealand (7.9 °C) dropped by 4 °C compared to May. See www.niwascience.co.nz/ncc/cs/mclimsum_07_06
