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.

Anyone who's been out in a small boat in early Spring knows just how
cold it is just offshore!
