Wales faces a variable spell of weather this week, with dry, sunny interludes interrupted by scattered showers and at least two more prolonged bands of rain, the Met Office says. Temperatures should remain near what is typical for early September, but conditions will often feel fresher in the wind and after rain.
What to expect each day
The start of the working week will be a contrast in little more than hours. Monday morning is likely to be rather grey in places with pockets of drizzle, especially across eastern parts of Wales. However, most areas should see improvement through the daytime with increasing brightness and some sunny spells. Peak daytime temperatures may reach around 20°C.
Rain is expected to return to north‑west Wales later on Monday and to spread more widely in the evening, with the likelihood of heavier and more persistent rain overnight. Temperatures by dawn are forecast to fall to roughly 11°C in places.
During Tuesday the overnight band of rain should clear eastwards in the morning, leaving a brighter spell for many. Yet the day will not be wholly dry: scattered showers are likely to develop in the afternoon, some of which could be heavy. A fresher feel is probable where winds increase, with a maximum of about 19°C quoted for Wales.
Wednesday currently looks most settled in the outlook, with fewer showers and more extensive sunny periods. Nights may turn noticeably cool, and frost is not suggested but some locations could feel chilly compared with daytime highs.
Unsettled conditions are expected to return on Thursday as another band of rain moves across the country. The timing and strength of that rain will vary by locality, so outdoor plans would be sensible to keep a weather‑proof option ready.
There is more optimistic news for Friday when the Met Office anticipates the rain to clear away and drier, brighter weather to reappear for many parts of Wales, leaving conditions suitable for outdoor activities.
Practical advice and forecast confidence
The pattern over the five‑day window is described as changeable. That means:
- Take layers — temperatures stay around seasonal norms, but wind and rain make it feel cooler at times.
- Carry rainproofs — keep a compact waterproof or umbrella handy, particularly on Monday night and Thursday when heavier rain is most likely.
- Check live updates — timing of rain bands can shift; consult the Met Office for short‑range updates if you have travel or event plans.
Confidence in the general pattern — that is, alternating brighter spells and episodes of rain — is reasonable for the period. However, the Met Office notes that the precise arrival times and intensity of the wet spells, especially the bands expected on Monday night and Thursday, may change as the systems approach. That uncertainty is typical for several‑day forecasts and is why local, closer‑to‑time information matters for detailed planning.

For most people this week will be about adapting plans around the showers rather than any sustained spell of extreme weather. Those with outdoor commitments should build contingency time into journeys and events on Monday night and Thursday when heavier rain is most likely to affect travel and comfort. Keep an eye on Met Office updates for sharper timing and any local warnings.
