How should I read the live forecast above for Gloucester?
The live forecast above updates automatically with data from the nearest Met Office observation point. Use the hour-by-hour slider to check temperature, wind speed and precipitation probability. The “feels like” reading accounts for Gloucester’s riverside chill, while the wind arrow shows direction — often from the southwest, bringing Atlantic moisture.
What defines Gloucester’s climate through the seasons?
Gloucester has a maritime temperate climate, heavily influenced by the Severn Estuary and the Cotswold escarpment. Winters are cool but rarely severe, with lows normally above freezing; frosts occur on clear nights. Summer temperatures are moderate, with occasional warm spells interrupted by Atlantic fronts. Rainfall is spread fairly evenly, though autumn and winter tend to be wettest. Winds can strengthen along the Severn Valley, especially during spring gales.

Are there local geography effects on Gloucester’s weather?
Gloucester lies in a broad valley beside the River Severn, which can trap low cloud and fog, particularly on winter mornings. The Severn Estuary funnels winds, making the city breezier than nearby Stroud, which sits in a Cotswold valley. To the west, the Forest of Dean hills sometimes block or divert rain-bearing fronts, creating slight local variations. The urban heat island effect is modest, keeping central Gloucester a degree or two warmer than open countryside at night.
What is the best time to visit Gloucester and what should I pack?
Late spring (May to June) and early autumn (September to October) offer the most settled weather, with lighter winds and fewer extreme conditions. For any visit, pack layers: a waterproof jacket is essential year-round, plus a warm fleece for cooler evenings. Comfortable footwear helps as cobbled streets and riverside paths can stay damp. Umbrellas are useful, but the wind may make them tricky near the cathedral.
What nearby areas do readers also check?
If you are planning a wider Severn Valley trip, you may also want forecasts for Cheltenham, Tewkesbury and Stroud. Each has slightly different conditions due to altitude and valley orientation.
What will the weather in Gloucester be like tomorrow?
Tomorrow’s conditions are shown in the live forecast above. In general, overnight lows are near 5–7°C in spring and autumn, with daytime highs reaching 13–16°C. Check the precipitation bar for rain timing, as showers often move through in the morning.
How reliable is the 10–14 day outlook for Gloucester?
Extended outlooks for the Severn Valley are moderately reliable for broad trends — such as whether an Atlantic low-pressure system is likely — but local showers and cloud cover can change within a day. Use the 10-day tab in the live forecast above and revisit it each morning.
Does it rain a lot in Gloucester?
Gloucester receives about two-thirds of the rainfall of the UK’s wettest areas (e.g. western Scotland). Rain falls on roughly 140 days per year, but many showers are light or short. Persistent heavy rain is uncommon, though the city can experience flooding when the Severn is high.
Is Gloucester ever affected by weather warnings?
Yes. Heavy rain can lead to localised flooding, and strong winds occasionally disrupt travel. The UK weather warnings page is updated when a warning is issued for Gloucestershire. Snow is rare but can cause disruption in the Cotswold hills above the city.
