According to the live forecast above, Mumbles is currently experiencing conditions typical for its coastal position, with temperatures in the low-to-mid teens Celsius and a moderate south-westerly breeze. This reflects the area’s exposure to Atlantic weather systems, which often bring cloud and patchy rain.
What is the weather pattern for Mumbles this week?
The live forecast above shows a settled but changeable pattern over the next few days. Daytime highs will range from 12°C to 16°C, with overnight lows dropping to 8°C–11°C. Winds from the south-west will keep conditions mild but occasionally gusty, especially along the exposed seafront. Rain is most likely midweek, with drier intervals either side.
How does Mumbles’ coastal location affect the forecast?
Mumbles sits on the western edge of Swansea Bay, meaning the sea moderates temperature extremes. The live forecast above reflects this: winter lows rarely dip below freezing, and summer highs are often a few degrees cooler than inland spots like Swansea city centre. Fog and low cloud can form quickly when warm air moves over the cooler sea, particularly in spring and early summer.
Is the BBC weather for Mumbles the same as for Swansea?
Not exactly. Mumbles is about 5 miles south-west of Swansea city centre, and its coastal position often means slightly cooler sea breezes and more persistent low cloud. The live forecast above gives a more localised reading than a city-wide forecast.
How reliable are 14-day forecasts for Mumbles?
For Mumbles, the Met Office and BBC weather 14-day outlooks are useful for spotting broad trends (e.g., a settled spell or a deep low), but day-to-day accuracy drops sharply after 7 days. The live forecast above is most reliable for the next 3–5 days.
Does AccuWeather Mumbles differ from the Met Office?
Yes, slightly. AccuWeather often uses a different model that can show sharper temperature swings, while the Met Office (which feeds the BBC) tends to be more conservative. For Mumbles, the live forecast above is the most consistent with local observations.
