San Francisco Skyline, Winter Fog and Haze. San Francisco, California. December 18, 2009. © Copyright 2009 G Dan Mitchell – all rights reserved.

Fog and haze obscure the winter skyline of downtown San Francisco, California.

Almost obscured by morning haze and fog, the San Francisco skyline is silhouetted against the backdrop of the morning light coming over east bay hills. This photograph was made from a vantage point in the Marin Headlands across the Golden Gate from the City. A number of downtown landmarks are visible including the Transamerica Pyramid, and beyond the downtown area a bit of the San Francisco Oakland Bay Bridge is barely visible.

The atmosphere above the Bay varies in astonishing ways throughout the year, and it never seems to be quite the same twice. While the summer often brings the familiar banks of ocean fog, winter brings the effects of fog from the other direction in the form of tule fog forming over the inland valleys. It can be completely clear – and, for the season, warm on the coast – yet a few miles inland the lower valleys may be filled with cold, wet, ground fog.

During these conditions, the moist air can move towards San Francisco and the Bay by way of the delta. That is more or less what was happening on this morning when the very most and hazy air from inland had created this soft atmosphere and light above The City, even as higher winter clouds in clear air moved far overhead, catching the morning sun light.
