and Portland 7.2°C.

That Portland temperature is a surprise. If correct, it suggests that
the water of the English Channel must still be pretty chilly.

9 - 9.5C SST in that area. However, I've noticed that during sea fog,
the air temperature is typically around 2C below that of the nearby
SST.

Over open sea the air temperature is normally lower than the SST . See

No sea fog, but air temperature below SST as normal. Under sea fog
conditions this phenomena moves over the coast.

That surprises me, as I thought that the mechanism for the formation of
sea fog was the sea cooling the air to its dewpoint. For the sea to cool
the air, the SST would surely have to be lower than that of the air? I'm
clearly missing something, as the measured temperatures can't lie.
