Winter Overview: Weather in Belfast in January
Weather in Belfast in January is influenced by its coastal location on the eastern shore of Northern Ireland. The proximity to the Irish Sea helps moderate temperatures, preventing extreme cold but often bringing damp and cloudy conditions. Surrounding hills and upland areas can create localized variations, with the potential for colder temperatures and occasional frost in elevated regions. Prevailing westerly winds from the Atlantic Ocean frequently carry moisture, resulting in high chances of rain and drizzle. Overall, the maritime climate ensures that temperatures typically remain in a narrow range, often between the mid-30sF and mid-40sF.
