Cornwall’s weather is shaped by the Atlantic, bringing mild winters, moderate summers and frequent showers. The live forecast above shows the immediate outlook, but the county’s microclimates mean conditions can shift quickly between north and south coasts.
What makes Cornwall’s weather different from the rest of the UK?
Cornwall’s maritime position keeps temperatures relatively stable year-round, rarely dropping below freezing in winter or climbing above 25°C in summer. The prevailing south-westerly winds carry moisture, so the county sees more rain than eastern England, but the south coast—around Falmouth and St Austell—tends to be drier than the north coast near Newquay and Bude. The UK weather hub has more regional context.
What should you expect for the next 10 to 21 days?
For a 10 day weather forecast UK view, Cornwall often shows a split: Atlantic fronts bring cloud and rain from the west, then clear spells arrive from the east. The weather in cornwall 10 days outlook typically follows this pattern, with longer-range 21 day weather forecast cornwall models indicating general trends rather than precise conditions.
