Check the live forecast above before heading out, as Cornwall’s weather is shaped by Atlantic systems that can shift from mild and damp to bright and breezy within hours. The county’s maritime climate means milder winters and cooler summers than inland areas, but also frequent cloud and rain from the southwest.
What makes Cornwall’s weather different from the rest of the UK?
Cornwall’s position as a peninsula jutting into the Atlantic gives it a strong maritime influence. This keeps winter temperatures around 5–8°C and summer highs rarely above 20°C near the coast. The same exposure brings more wind and rain than eastern counties, especially from autumn to spring. The UK weather hub shows how this compares with other regions.
How reliable are longer-range forecasts for Cornwall?
Forecasts beyond 10 days become less certain due to the fast-moving Atlantic weather patterns. A 10 day weather forecast UK gives a useful trend, but a 21 day weather forecast Cornwall should be treated as a broad outlook rather than a day-by-day guarantee. For immediate plans, the live forecast above is your best guide.
