For the latest BBC Weather forecast for Weymouth, refer to the live forecast above. As a coastal Dorset town, Weymouth’s conditions often differ from inland Dorchester, with sea breezes moderating temperatures year-round.
What does the coastal setting mean for Weymouth weather?
Weymouth sits on the Jurassic Coast, so its climate is heavily influenced by the English Channel. Summers are typically milder than inland areas like Dorchester, while winters stay slightly warmer. The sea breeze can bring cloud and occasional sea fret, especially during spring and early summer. For a broader regional picture, the Bristol Weather page includes comparisons across the South West.
Where can I find long-range forecasts for Weymouth?
For a 14-day or 21-day outlook, both BBC Weather and the Met Office provide extended forecasts. BBC Weather Weymouth 14-day forecasts use Met Office data, so you can check either source. For a concise weekly view, the 10 Day Weather Forecast UK page offers a snapshot, while the UK weather hub links to all regional pages.
How accurate is the BBC Weather forecast for Weymouth?
BBC Weather uses Met Office data, so reliability is high for 3–5 day outlooks. Longer-range forecasts, such as the 14-day forecast for Weymouth, should be treated as trends rather than precise predictions.
Where can I check Met Office weather warnings for Weymouth?
The Met Office website issues official yellow, amber and red warnings for wind, rain and coastal conditions. You can also see these alerts on the BBC Weather page for Weymouth, which displays them alongside the hourly forecast.
Does Weymouth have a microclimate compared to Dorchester?
Yes. The sheltered bay and coastal position mean Weymouth often enjoys milder conditions than inland Dorchester, especially in winter. However, sea fog and onshore winds can bring sudden changes, particularly during spring and early summer.
