Enough folks have asked me how I chase fog shots that I’ve added useful tools / links I use to chase fog.
1) Is the government saying there will be morning fog? Check here first!
2) SFO Aviation data: If it’s good enough for our planes, then it’s good enough for you. Look for “Ceiling” in the forecast. If it’s 800 feet or below, then there’s a good chance of low fog. There might not be fog, but if there is it will be low. I got a shot with a 900 feet ceiling but that more had to do with extreme luck. A ceiling of 1500 feet is great for Mount Tamalpais.
3) The “weatherforyou.com” site is almost no longer useful (as of 9 May 2024). I just wish I could zoom into the maps. It shows you fog cover for different blocks of time.
4) Also, it helps to consult a webcam.
5) There’s also the Escaype App but you gotta pay for it.
I hope this helps. Chasing fog is like hitting in baseball. If you get it 3 out of 10 times, then you’re a success. There’s nothing like seeing the fog roll in low into the San Francisco Bay during dusk or dawn.
