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 the centre, by the Peace Park, 43 km from the airport (HIJ): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

How busy it gets

December: quiet. Busiest in August; quietest in January, June and December.

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

Before you go
