You need the air to be more moist...the way to get it to carry a higher percentage of water vapor is to warm it up.

Johnstone found that the contrast between inland and coastal temperatures was much greater from 1900 to 1930 than during the last 60 years, indicating that summers on the coast were much foggier in the early 20th century.

Post hoc ergo propter hoc?

I had always thought that the heat caused a thermal low inland was the cause of the onshore flow and the fog.
