 Fog on our field trip to Montana De Oro!

During our field trip, we saw fog over the waters close by and in the distance. I believe that this would be considered coastal fog, as it is very common off the central coast. I also noticed that the fog was forming more towards the ground rather than high up.

For the fog to form, there should be cool ocean air that moves inland. As this air passes over the warm land, the moisture is condensed, which often happens with a little bit more humidity forming this phenomenon. This fog can cover large areas. Being many miles horizontally and can reach up to hundreds of feet high, sometimes going above valleys and tall areas. Depending on the day, the fog could last for hours or even the whole day. If the Sun is out, it is more likely to last a short time as it will evaporate the water vapor, and it is easy for winds to push it out or away.
