Coastal fog or sea mist usually burns off by late morning when the land warms. If the wind is light, it may linger into the afternoon, especially during spring tides. The live forecast above indicates any mist will clear by noon.
Does St Agnes get more rain than the average Cornish town?
No – its annual rainfall of around 1,100 mm is close to the Cornish average. However, the coast can catch heavier showers when southwesterly fronts stall, while inland areas may remain drier.
