Gardening weather in Belfast

If you're planning anything outdoors in Belfast, the city is genuinely drier than its reputation suggests — the Donegal hills to the west catch most of the rain coming in off the Atlantic, leaving Belfast with significantly less rainfall than Galway or Cork. The trade-off is wind: Belfast Lough funnels weather through quickly, the city is windier than most of England, and snow days do happen — typically about eight a year.
