This forecast covers Saturday 30 August 2025 to Wednesday 03 September 2025.
Based on ECMWF deterministic guidance.
Headline: Predominantly mild with patchy drizzle and light rain, increasing to moderate rain in parts of South West and Wales by midweek.
Saturday 30 August to Monday 01 September
England and Wales will experience mainly dry and mild conditions with extensive cloud cover and patchy drizzle or light rain, especially in western and northern Wales and parts of South West England. Rainfall amounts are generally light, with drizzle persisting through much of the day in these areas. Eastern and southern England, including East Midlands and South East, will see mainly dry and clear spells with occasional light drizzle. Winds remain moderate, generally from the south or southwest, with no significant heavy showers expected.
Tuesday 02 to Wednesday 03 September
A gradual increase in rainfall intensity is forecast across Wales and South West England, with moderate rain developing by Wednesday morning. This rain will be more persistent and locally heavier in these regions, while eastern and northern England remain mostly dry with occasional drizzle. Drizzle and light rain continue in central and southern England, with no significant heavy precipitation expected there. Winds strengthen in the South West and Wales, reaching fresh to strong gusts at times, particularly on Wednesday.
Nothing currently indicated that seems likely to exacerbate or create new flood risk.
Coastal/tidal information
Tidal conditions will be in a neap cycle, with high tides gradually reducing through the period and reaching the lowest neap tides by Tuesday and Wednesday. No large spring tides are expected. Coastal winds will strengthen notably in South West England and Wales by midweek, with gusts reaching Beaufort Force 5-6 during high tide periods on Wednesday. This wind-tide interaction may cause locally elevated coastal water levels but no exceptional tidal surge is forecast. Other coastal areas will experience lighter winds, generally Force 2-4.

Based on ECMWF deterministic guidance.
Headline: Predominantly mild with patchy drizzle and light rain, increasing moderate rain mainly in the South West by midweek.
Saturday 30 August to Sunday 31 August
England will experience generally mild and mainly dry conditions with extensive cloud cover in many areas. Light drizzle and patchy drizzle are expected at times, particularly in the North West and parts of the Midlands. Rainfall amounts remain low, with only isolated light rain or drizzle in the South West and South East. Overall, rainfall totals are modest and unlikely to cause flooding.
Monday 1 September to Wednesday 3 September
A gradual increase in rainfall is forecast, especially across South West England where moderate rain is likely from Tuesday into Wednesday. Drizzle and light rain will continue in the Midlands and East, with occasional drier spells. Northern and North West England will see mainly light rain or drizzle, with some overcast conditions. Rainfall accumulations will be higher in the South West, but moderate rain is not expected to be heavy or prolonged enough to significantly raise flood risk.
Nothing currently indicated that seems likely to exacerbate or create new flood risk.
Coastal/tidal information
The tidal cycle will be at neap levels throughout the forecast period, with high tides gradually reducing towards the lowest neap tide midweek. No large spring tides are expected. Coastal winds will generally be moderate force 3-4, occasionally fresh force 5 in exposed coastal areas, but these do not coincide with high tides. Therefore, no significant wind–tide interaction is anticipated to increase coastal flood risk.

This forecast covers Saturday 30 August 2025 to Wednesday 03 September 2025.
Based on ECMWF deterministic guidance.
Headline: Predominantly light rain and drizzle with increasing moderate rain and breezy conditions by midweek.
Saturday 30 August to Monday 01 September
Wales will experience mainly light rain and drizzle, with occasional light rain showers, especially in western and southern areas. Early Saturday sees mainly dry and clear conditions in the north and east, with drizzle developing through the day across much of the region. Rain amounts are generally light, though persistent drizzle may cause minor surface wetness. Cloud cover will be variable, with some overcast spells mainly in the west. Winds remain moderate, generally from the south-west to south, with gusts mostly below fresh breeze strength. No significant heavy rainfall or thunderstorms are expected during this period.
Tuesday 02 to Wednesday 03 September
From Tuesday into Wednesday, light rain and drizzle continue early in the day, mainly in western and southern parts. By Wednesday morning, moderate rain is forecast to develop, particularly in southern and central Wales, with rainfall rates increasing to around 2-5 mm/hr locally. This moderate rain will persist into the afternoon before easing later. Winds strengthen notably on Wednesday, with gusts reaching strong breeze to near gale force (Beaufort 6-7) especially along the coast. This increase in wind and rain intensity may raise localized surface water flood potential, particularly in coastal and low-lying areas.
Overall, rainfall totals remain moderate with no prolonged heavy rain episodes.
Nothing currently indicated that seems likely to exacerbate or create new flood risk.
Coastal/tidal information
The tidal cycle is in a neap phase, with high tides gradually reducing in height through the forecast period. No large spring tides are expected. Coastal winds strengthen notably on Wednesday, reaching fresh to strong breeze (Force 5-6) with gusts near gale (Force 7) during high tide periods. This wind-tide interaction may enhance wave action and coastal water levels locally, but with neap tides, significant coastal flooding is unlikely.

This forecast covers Saturday 30 August 2025 to Wednesday 03 September 2025.
Based on ECMWF deterministic guidance.
Headline: Mostly dry with light rain and drizzle early, increasing to moderate rain in western and southern Scotland by midweek.
Saturday 30 August to Monday 1 September
Scotland will start with mainly dry conditions and mainly clear to partly cloudy skies, especially in eastern and northern areas. Light rain and drizzle are expected to develop through the day in western and southern parts, becoming more persistent by evening. Rain amounts will generally be light, with drizzle and light rain dominating. Winds will be moderate to fresh in places but not expected to cause significant impacts.
Tuesday 2 to Wednesday 3 September
Rainfall will increase in intensity and coverage, particularly across western and southern Scotland, where moderate rain is forecast. Light rain and drizzle will continue in eastern and northern areas but with less intensity. Rain totals will be higher in the west and southwest, with some periods of moderate rain especially on Tuesday afternoon and Wednesday. Winds will remain moderate to fresh, with gusts increasing locally.
Nothing currently indicated that seems likely to exacerbate or create new flood risk.
Coastal/tidal information
Tides will be in a neap cycle, with high tides gradually reducing in height through the period. No large springs are expected. Coastal winds will be moderate to fresh (Force 4-5) at times, particularly in western and southern coastal areas during Tuesday and Wednesday, coinciding with higher tides. This may enhance wave action but with no significant tidal surge risk indicated.
