Belfast is located on Ireland’s east coast at the mouth of the River Lagan. Its waterfront location and northern latitude lend the city a temperate climate, with generally chilly, windy, and rainy weather. Temperatures throughout the year vary only slightly.
The Irish summer brings long, relatively warm summer days. On the summer solstice, in June, the sun rises before 5:00 a.m. and doesn’t set until well after 10:00 p.m. Temperatures in June range between 48 and 62 degrees. Dressing in layers is the key to comfort in Belfast.
Average temperatures in January sway between 35 and 45 degrees. Relatively speaking, that’s not all that cold, but the days are drearily short. On the shortest day of the year, the winter solstice in December, the sun doesn’t rise until about 8:45 a.m. and then sets by 4:00 p.m.
