Dolly Sods is a high plateau in the Allegheny Mountains, open heath and wind-bent red spruce above 4,000 feet that feels more like Canada than West Virginia. Because of the elevation, fog here doesn't just sit in the valley below, it moves directly across the landscape, drifting through the spruce and over the exposed rock outcrops at eye level.

Bear Rocks and the Lion's Head area are the standout viewpoints, both offering wide views east into the valley where fog often pools below the plateau while the sods themselves catch drifting cloud. The boardwalk trail through the bog gives a lower, more intimate composition when fog is moving through the spruce.

Summer and early fall mornings are the most active, when warm, moist valley air rises and condenses against the cooler plateau. Because conditions here are driven by elevation as much as overnight cooling, fog can show up even when lower valleys stay clear, so it's worth checking even on nights that don't look promising by usual standards.



Humidity alone isn't enough. Wind alone isn't enough. Cloud cover alone isn't enough. Photogenic valley fog requires several conditions to line up at once, and most weather apps don't read them together.

Dew Point Depression
When air temperature and dew point converge below 2°C, the air is near saturation. This is the single strongest fog predictor and the first thing FogCast checks.
Wind Speed
Fog needs calm air. Below 5 km/h is ideal. Above 15 km/h, fog disperses before it can pool in the valley. A standard weather app won't flag this combination.
Overnight Sky Clarity
Clear overnight skies let the ground cool rapidly, pushing surface temperatures toward the dew point. Counterintuitively, clouds overnight suppress radiation fog.
Temperature Trend
FogCast reads the overnight temperature arc. If temps are converging toward the dew point hour by hour, fog probability increases significantly by pre-dawn.

Frequently asked
Can I check FogCast on the website?
This page shows a preview of current conditions, including humidity, wind, temperature, and dew point. The full FogCast score, 7-day outlook, push notifications, and best shooting windows are available exclusively in the LightCast app for iOS.
Is FogCast free?
The current conditions preview on this page is free, no account needed. The full FogCast tool is in the LightCast Suite iOS app, which includes a 7-day free trial. After the trial it's $2.99/month, cancel anytime in the App Store.
Why use FogCast instead of checking humidity?
Humidity alone doesn't tell you whether photogenic fog is likely. High humidity with strong wind produces no fog at all. FogCast combines dew point depression, wind speed, overnight sky clarity, temperature trend, and visibility into a single score built specifically for fog photography planning.

What is FogCast's scoring scale?
FogCast scores fog conditions from 0 to 100. A score of 75 or above indicates dense fog is expected. 55 to 74 means fog is likely and worth chasing. 35 to 54 suggests patchy mist is possible. Below 35, conditions are unlikely to produce photogenic fog. The full score is available in the LightCast app.
