Northern Ireland climate

Northern Ireland – the six counties of Antrim, Armagh, Down, Fermanagh, Londonderry and Tyrone on the north east side of Ireland – has a temperate maritime climate, like the rest of the country. It is influenced by the Gulf Stream which makes Ireland warmer than it should be given its latitude. The summers are warm and the winters are mild. Rain, however, is never far away, and the north of the country gets more snow than the republic during the winter.
