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 Douglas, 12 km from the airport (IOM): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

How busy it gets

May: busier than usual. Busiest from June to August; quietest from January to March.
