I suppose these misty/foggy/low cloud mornings are an ongoing symptom of so much rain and therefore wet ground.
Four such mornings in a row in my location. Rather than sunshine from early on it’s so dull lights are needed inside and the heating keeps clicking on too even though we set it at 18c!l
No light, no warmth, perennial Autumn. It literally is like ‘mellow mists’ of October every morning!
I’m sure it will clear later but Spring is not reaching its full potential in my opinion. There’s only a finite period of the year where it can be sunny from 06.00!
