Belfast Weather Forecast

Belfast weather including a 5 day forecast for temperature, wind speed, UV and weather warnings for today's weather. Alternatively mapped forecasts are available for temperature, rainfall, pressure and cloud.


Belfast, lying on the coast to the east of Northern Ireland, is the largest city in Northern Ireland. The area has been in continual occupation since at least the Bronze Age. There is a 5,000-year-old henge located near the city while the remains of Iron Age hill forts top the surrounding hills.

The city is flanked to the north, northwest and the southeast by a series of hills, while the city sits on a low plain with a number of rivers threading their way to the coastal Lough.

The name "Belfast" is derived from the Irish, Beal Feirsde, referring to a sandbar or tidal ford across a river's mouth. This sandbar was formed at the meeting of rivers which then flows into Belfast Lough at what is now called Donegall Quay.

In more recent history, Belfast has been a major manufacturing centre and was the home of one of the world largest shipbuilders, Harland and Wolff who built the RMS Titanic, which famously sunk on its maiden voyage in 1912.

Climate notes:

The climate of Belfast is milder than some other locations in the world on a similar latitude, due to the warming influence of the Gulf Stream. The climate is temperate with a relatively narrow range of temperatures and rainfall throughout the year.

More recent weather related information:

Belfast has a history of suffering flooding stretching back over the last century with significant impacts as recently as 2012, 2008 and 2007.

East Belfast has suffered the most inundations with roads under water, disruption to travel and daily life with homes flooded sometimes repeatedly. As part of living with this situation there is a new flood alleviation scheme for East Belfast being constructed after the 2012 floods.
