This forecast covers Monday 01 September 2025 to Friday 05 September 2025.
Based on ECMWF deterministic guidance.
Headline: Persistent light rain and drizzle across Wales and western England early in the week, easing with drier and clearer conditions by midweek; southern and eastern England remain mostly dry with occasional light rain.
Monday to Tuesday (01-02 September)
Wales and South West England will experience widespread light rain and drizzle, with moderate rain developing in places, especially in western and upland areas. Rainfall totals are modest but persistent, mainly affecting western Wales and the South West. Elsewhere in England, including the Midlands, East, and South East, conditions are generally dry with mainly clear to partly cloudy skies and occasional light drizzle. Northern England and Yorkshire see mainly dry conditions with some cloud cover.
Wednesday to Friday (03-05 September)
Rainfall decreases across Wales and South West England, with light rain and drizzle becoming more intermittent. Moderate rain episodes are possible early Wednesday but tend to fade through the day. Eastern and southern England will remain largely dry with mainly clear or partly cloudy skies, and only isolated light drizzle. Northern England and the Midlands see mainly dry and clearer conditions. Overall, rainfall amounts are low and scattered, reducing flood risk.
Nothing currently indicated that seems likely to exacerbate or create new flood risk.
Coastal/tidal information
Tidal conditions will transition from neap tides early in the week to a mid-cycle tide building towards springs by Friday. High tides increase gradually, but no large spring tides are expected during this period. Coastal winds will be moderate to fresh (Force 4-5) mainly along the South West and Welsh coasts, especially around midweek when moderate rain occurs. Wind-tide interaction may cause locally elevated sea levels but no significant coastal flooding risk is anticipated. Elsewhere, winds remain lighter, with minimal impact on tidal levels.

This forecast covers Monday 01 September 2025 to Friday 05 September 2025.
Based on ECMWF deterministic guidance.
Headline: Periods of light to moderate rain with drizzle, mainly in the south and west; drier and mainly clear spells elsewhere.
Monday 01 to Tuesday 02 September
England will see mainly dry and clear conditions in the east and northeast, with light drizzle and occasional light rain developing in the south and southwest. Moderate rain is possible in parts of the southwest by Tuesday morning, with drizzle persisting into the afternoon. Northern and eastern areas remain largely dry with mainly clear skies.
Wednesday 03 to Friday 05 September
A band of light to moderate rain and drizzle will affect much of southern and western England, particularly the southwest and parts of the Midlands, with some moderate rain episodes on Wednesday and Thursday. Eastern and northern England will experience mainly dry conditions with occasional drizzle and some clear spells. Rainfall totals remain modest, with no heavy or persistent downpours forecast.
Overall, rainfall is generally light to moderate with drizzle dominating, especially in southern and western regions. No significant heavy showers or thunderstorms are expected.
Nothing currently indicated that seems likely to exacerbate or create new flood risk.
Coastal/tidal information
The tidal cycle is transitioning from neap tides towards mid-cycle tides, building towards spring tides by Friday. High tides increase in height through the period but remain below large spring tide thresholds. Coastal winds will be moderate to fresh (Force 4-5) mainly along the south and southwest coasts, coinciding with higher tides midweek and towards the end of the forecast. This may enhance wave action but no extreme wind-tide interactions are expected.
Winds elsewhere are generally lighter, with gentle to moderate breezes inland and along eastern coasts.

Based on ECMWF deterministic guidance.
Headline: Predominantly light rain and drizzle with moderate rain episodes midweek, easing towards Friday.
Monday 01 to Tuesday 02 September
Wales will experience mainly light rain and drizzle, especially overnight into Tuesday morning. Rainfall amounts are generally light, with drizzle persisting through much of Monday and early Tuesday. The wettest conditions are expected in western and southern areas, with light rain gradually easing by Tuesday afternoon. Cloud cover will be extensive overnight but will thin during daytime, allowing some breaks in the west and south.
Wednesday 03 to Thursday 04 September
Moderate rain is forecast midweek, particularly Wednesday afternoon and evening, mainly affecting western and southern parts of Wales. Rainfall totals will be higher during this period, with persistent light rain and drizzle continuing elsewhere. Conditions will remain damp with overcast skies and occasional drizzle extending into Thursday morning. Rain gradually decreases Thursday afternoon with some clearing, especially in eastern and northern areas.
Friday 05 September
A drier and brighter day is expected across Wales with mainly clear to partly cloudy skies. Drizzle may occur briefly in coastal and western areas early, but overall rainfall is minimal. Winds will ease, and conditions will become more settled by late Friday.
Nothing currently indicated that seems likely to exacerbate or create new flood risk.
Coastal/tidal information
The tidal cycle is transitioning from neap tides early in the week to mid-cycle tides building towards springs by Friday. High tides increase in height through the period but remain below large spring tide thresholds. Coastal winds will be moderate to fresh (Force 4-5) mainly from the south to southwest, peaking midweek. These winds coincide with higher tides midweek, potentially enhancing wave action along exposed coasts but without significant risk of coastal flooding. Wind speeds ease towards Friday as tides build further.

Based on ECMWF deterministic guidance.
Headline: Persistent light rain and drizzle with occasional moderate rain, mainly in western and northern Scotland.
Monday 01 to Tuesday 02 September
Scotland will experience widespread light rain and drizzle, particularly across western and northern areas including the Highlands and islands, with moderate rain developing in some western coastal and upland zones. Eastern and southern parts will see lighter, more intermittent drizzle and mainly dry spells. Rainfall totals will be moderate in the west, lighter elsewhere.
Wednesday 03 to Friday 05 September
Conditions gradually become drier with mainly drizzle and light rain persisting in western and northern regions, while eastern and southern areas see more frequent dry and clearer spells. Rainfall amounts will be generally low, with drizzle dominating. Moderate rain episodes are less likely but possible in western coastal and island areas early in the period.
Overall, rainfall is mostly light to moderate, with no significant heavy or prolonged downpours forecast. Nothing currently indicated that seems likely to exacerbate or create new flood risk.
Coastal/tidal information
The tidal cycle is currently at neap tides, building towards mid-cycle tides by Friday, increasing tidal ranges but not reaching large spring tides. Coastal winds are generally moderate to fresh (Force 4-5) at times, especially along western and northern coasts during high tides midweek and towards the end of the forecast period. Wind gusts locally reach strong (Force 6) in some western coastal areas, which may enhance wave action but no extreme coastal flooding is expected.
