Today has seen a mixture of warm, sticky sunshine & coastal mist & fog at various levels

Following the clearance of a cold front around noon the air remained very humid, (and it got warmer!) No fog over the open sea, but the sunshine at low tide led to ‘steaming beaches’ (beach mist) and uplift at the windward cliffs created ‘clifftop’ fog.

The following 2 photos show this, the mistiness just above Praa Sands beach, a clear slot, then cliff top fog http://www.turnstone-cottage.co.uk/F.html

The mist caused some interruptions to flights to Scilly, but if the Royal couple haven't got there yet, they haven't tried very hard. They've been flying quite happily much of the time fttps://www.flightradar24.com/50.61,-2.46/7

Cu readily formed over the land - also shown in the picture.
