Ten-year averages for this calendar month. A rainy day is one with at least 1 mm of rain, as a weather station counts it. The model these figures come from drizzles more than a rain gauge, the more so the warmer the month, so its days count from 2 mm, rising to 5 mm in the hottest.

Weather read at Waitangi, the islands' town, 17 km from the airport (CHT): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

How busy it gets

May: quiet. Busiest from November to February; quietest in March, May, June, July and September.

  • Humidity averages 80%; breathable fabrics dry faster.

Each line is a threshold over the ten-year figures above, not advice from anywhere else.
