About the weather in Belfast
Belfast lies on Belfast Lough and is sheltered by hills to the north and west, which helps keep it a little drier than the Atlantic coast. Weather changes quickly and showers pass through often, but long wet days are less common than people expect.
Across Ireland, spring is cool and bright with showers, summer highs are typically in the high teens with long evenings, autumn is the wettest and windiest stretch as the Atlantic fronts return, and winter is mild for the latitude with frost on clear nights. Rain can arrive in any month.
