Belfast sits in Northern Ireland, which shares Ireland’s mild, wet maritime climate, with rain distributed fairly evenly across the year and few dramatic seasonal extremes.
Sitting where the River Lagan meets Belfast Lough, the city’s flood risk includes both rainfall in the surrounding hills and tidal effects from the lough. Because flooding here tends to build gradually from sustained rain rather than sudden downpours, radar is used alongside river monitoring to track how long a wet spell is likely to persist.
