Quoting:Is such a thing possible, heat off the North Sea at this time of year?

Very definitely, yes! The North Sea is currently +7°C, so when the air over the land is below freezing, a light northeaster brings in air warmed up by the sea. Snow right on the coast here is very rare, though somewhat commoner where I am 10km inland.

Another interesting fact: Tynemouth (Northumbs) and Tresco (Scilly) have the same absolute minimum temperature of -7°.

If the North Sea wasn't there, an east wind from Siberia would bring the temperature down to -30° or lower.
