Anticyclones initially tend to bring a good deal of settled and dry weather by day, but as the sun goes down in the evening, the air temperature steadily drops and eventually cools to a point where any moisture condenses out into fog - hence why the foggiest conditions are often found towards dawn.Anticyclones initially tend to bring a good deal of settled and dry weather by day, but as the sun goes down in the evening, the air temperature steadily drops and eventually cools to a point where any moisture condenses out into fog - hence why the foggiest conditions are often found towards dawn.
There has also been very little wind to help clear it and as we're into November the sun is lower in the sky, so it's weaker as a heat source, meaning the fog has persisted all day in some areas.There has also been very little wind to help clear it and as we're into November the sun is lower in the sky, so it's weaker as a heat source, meaning the fog has persisted all day in some areas.
