Another Foggy Day

After the first fog of the day had cleared, we had a few minutes of sunshine. But the bottom layer of cloud in this picture was rising rapidly, moving from left to right of the picture, along the line of the River Dart. Soon it had spread everywhere, the sea and headlands were again lost in the fog, and that's how it's stayed all day.

I've tried calling it 'sea mist' to myself. But I'm afraid it's still fog.
Fog fog fog.
Ugh!
