Photo Story: Fog on Penobscot Bay

Fog and the Maine coast go together.  This is especially true in the summer, when the prevailing southwest breeze can bring moist warm air off the land which then passes over the cold ocean water, causing the moisture in the air to condense.  If you spend a week on the Maine coast, you will need to be prepared for a few days of fog. Even in summer, this means fleece jackets or wool sweaters, and sometimes both.

I have read that there are several kinds of fog.  From what I can tell, the type of fog I have described above and which is shown in the photo below is called “Advection fog”.  Advection refers to the wind bringing moist air over a cool surface. Advection fog can also occur when warm air passes over thick snow-pack.

Into the Fog

The photo was taken in August at 7:00 a.m.  The location was Penobscot Bay.  An hour earlier, the morning was beautifully clear, and I witnessed an outstanding sunrise. I knew that it would be an interesting morning because I also saw in the distance a thin band of fog. It made the horizon look much nearer, and it began coming closer. Then, coming around a point of land to my right, and outside the field of view of the camera, flowed a white “tongue” of fog gliding across the surface of the water.  As you would expect, this did not seem to phase the lobstermen seen here heading out to check their traps. A moment after capturing this image, the lobsterboat disappeared into the approaching fog.  I guess that’s no big deal for those who know the sea. 

Another few minutes went by and then I, watching all of this from a rocky beach, was fully engulfed by fog. It was then time to walk back to the cabin, put on a sweater, and have another cup of coffee.

Below is a black and white version.  It’s the same photo, but converted to black and white in Adobe Lightroom.
