At least it is when you're on the beach looking at clearer skies over
the sea, with the mist forming just offshore (rather than at cliff top
height - which is absolutely fine!). You wait in vain as each clearer
patch approaches, knowing full well that it will fill in a short way
offshore. This phenomena is one of the reason Scilly is often quite
sunny when the forecast is for mist & drizzle, as it was when I was
last there. Not enough uplift.

Last Saturday was such a day, and there are some nice atmospheric pics

Drier air did clear the mist late in the day. Love the one of
Longships.

Extensive low cloud this morning, with sea fog patches below. Signs of
it clearing on the north coast http://www.nci-stives.org/basiccamera.htm
