The live forecast above gives the BBC weather for Chichester, including today’s conditions and the week ahead. For a local perspective, this page breaks down what to expect over the next few days and how the coast and South Downs influence the outlook.
What’s the weather like in Chichester today and tomorrow?
Checking the live forecast above is the quickest way to see current temperatures, wind and rain. For Chichester, autumn conditions often mean crisp mornings followed by cloud building from the English Channel. Tomorrow’s weather in Chichester should follow a similar pattern, with the chance of a light shower in the afternoon. The coastal influence keeps temperatures milder than inland areas, but fog can form over the harbour in the early hours.
Can you rely on the 10-day and 14-day outlook for Chichester?
Longer-range forecasts — such as the weather in Chichester for 10 days or the Chichester weather 14-day forecast — become less certain, but the general trend from the live forecast above is reliable. For a more specific view, the Met Office weather Chichester service and BBC weather Chichester 14-day updates both use the same core data. Nearby villages like Sidlesham (BBC weather Sidlesham is available online) share a similar coastal pattern. If you need planning for the week ahead, check the 10 Day Weather Forecast UK page for a broader picture.
How does the coast affect Chichester’s weather?
The English Channel moderates extremes: winters are milder and summers cooler than inland Sussex. Sea breezes can strengthen in the afternoon, and low cloud often lingers over the harbour when inland areas are clear.
Where can I get the Met Office weather for Chichester for 14 days?
The Met Office provides a 14-day outlook for Chichester via its website. The live forecast above also includes a 14-day view from the same data. For the most accurate planning, combine that with the BBC Weather Chichester page, which uses Met Office information.
Is the weather in Chichester the same as in Sidlesham?
Sidlesham, a few miles south on the Manhood Peninsula, shares Chichester’s coastal climate. However, it can be slightly windier and cooler due to its proximity to the open sea. BBC Weather Sidlesham offers a dedicated forecast for that village.
