We consider fog just a variation of another nice day in L.A. Through May we experience May Gray, the arrival of the marine layer into the city drawn by the heating of the interior of the state as the days get longer and warmer. And then, in June, it’s time for June Gloom as the same phenomena likely continues in the early part of the month. Our Los Angeles private tour guests taking early morning or late afternoon tours will probably appreciate the cooler temperatures that accompany the white wisps of moisture as the giant ocean cooled cloud marches in from the beach. As you see in this aerial photograph from a recent combination helicopter and ground tour, the fog is not solid and there are always large patches of beach that see the sun. We warn our guests to be wary of sun exposure because the harmful rays penetrate the thin fog layer. That’s why we carry sunscreen with us. Hats and umbrellas would be a good idea, too.
