Why fog is hard to predict
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.

Fog photography at Isle of Skye
The Isle of Skye sits off the northwest coast of Scotland in the path of Atlantic weather systems, and its rugged combination of sea lochs, moorland, and the Cuillin ridge makes it one of the most atmospheric fog photography locations in Europe. Low cloud is the norm rather than the exception — Skye averages over 250 days of cloud annually — and the fog that rolls in off the sea and down from the Cuillins is thick, persistent, and completely transformative. The Black Cuillin, normally a dramatic jagged ridgeline, becomes a series of ghostly emerging dark peaks when cloud sits at 300 to 500 meters.
The Quiraing on the Trotternish Peninsula is one of the best fog photography locations on the island. The dramatic landslip landscape of rocky pinnacles and grassy ledges, partially obscured by moving cloud and mist, produces images with enormous depth and atmosphere. The Old Man of Storr, a few kilometers south, is equally striking when fog drifts through the basalt columns. Autumn, from September through November, produces the most dynamic fog conditions, with morning mist, shifting cloud, and frequent dramatic light breaks.
Skye fog is mostly orographic and advection fog rather than radiation fog, driven by moist Atlantic air meeting the island's topography. Rather than looking for calm clear nights, watch for a stable maritime air mass arriving from the southwest after a frontal passage. When visibility is 1 to 3 km and the Cuillins are partially obscured, the photographic conditions are often at their best.

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.
