Ystalyfera is seeing a cool, damp start today with overcast skies and patchy light rain, as shown in the live forecast above. This unsettled pattern is typical for the time of year, with brisk south-westerly winds keeping conditions fresh across the Swansea Valley.
What is the outlook for the rest of the week?
The coming days will remain changeable, with further spells of rain arriving from the Atlantic, particularly on Wednesday and Friday. Temperatures will hover near seasonal averages, so you’ll want a waterproof jacket if you’re heading out in Ystalyfera or travelling to nearby Swansea or Cardiff. Brighter, drier interludes are likely between weather fronts, especially on Thursday afternoon.
Will it be frosty overnight in Ystalyfera?
Overnight lows will stay above freezing, so widespread frost is unlikely. However, clearer spells on Thursday night could bring a touch of ground frost in sheltered spots.

Is it going to rain all day in Ystalyfera?
Not continuously. The rain will be showery and intermittent, with drier breaks this afternoon and again on Thursday. Keep an eye on the live forecast above for the timing of heavier bursts.
How windy will it get in the Swansea Valley?
Gusts could reach 30–35 mph on Wednesday, especially on higher ground. It will be breezy but not severe enough for warnings, though take care if you’re walking near exposed areas.
Should I plan outdoor activities this weekend?
Saturday looks the better day, with lighter winds and a chance of some sunshine. Sunday may turn wet again. For a longer view, see our 10 Day Weather Forecast UK.
