What will the weather in Swansea be like tomorrow and next week?

If you are planning further ahead, the weather in Swansea 10 days from now and the 14 day weather forecast in Swansea are both viewable in the same data, giving a clear picture of any settled or unsettled spells on the way.
How reliable is the longer-range outlook for Swansea?
The 14 day weather Swansea Met Office data and the 15 day weather forecast Swansea shown above come from the same modelling used by forecasters across the UK. Confidence is highest for the first five days; beyond that, trends for rain or drier interludes become useful but less precise.

What is the best time of year to visit Swansea for decent weather?
Late spring through early autumn (May to September) offers the mildest conditions and longest daylight. July and August are warmest, though the coastal breeze keeps things comfortable. Rain is possible year-round, so always check the live forecast before travelling.
Does Swansea get a lot of rain compared to the rest of the UK?
Swansea receives around 1,200mm of rain annually, which is above the UK average of about 1,100mm. The surrounding hills of the Brecon Beacons capture more moisture, but the city itself is sheltered compared to inland valleys. Showers can be sudden but often pass quickly.
How does Swansea’s coastal position affect its temperature?
The sea moderates temperatures year-round: winters are milder than inland areas such as the Brecon Beacons, and summers are slightly cooler. This means fewer frosts in winter but also less extreme heat in summer. The breeze off Swansea Bay can make it feel fresher than the actual air temperature.
