Hurricane Ridge in Olympic National Park sits at 1,594 meters above the Strait of Juan de Fuca and the Elwha River valley, giving photographers a high vantage point above the lowland fog systems that frequently fill the Olympic Peninsula below. When the valleys and strait are fogged in and Hurricane Ridge is clear, the result is one of the most spectacular above-fog panoramas in the Pacific Northwest — a sea of white stretching to the horizon with the Olympic peaks rising above it.

The Hurricane Ridge Visitor Center parking area and the meadow trails give broad south-facing views over the fog-filled valleys. The road to Obstruction Point, when open, extends the above-fog ridgeline perspective for miles. Looking north toward the strait, the fog often layers in bands between the ridges. September and October are the most reliable months for low valley fog with a clear ridge, before winter snowfall and storms close access. Early morning is essential — the fog burns off quickly once the sun clears the eastern peaks.

Hurricane Ridge fog photography requires fog in the valleys below while the ridge stays above the inversion layer. This happens when a high pressure system builds overnight, allowing cold air to pool in the valley floors while the ridge sits in clear, calm air above. Check valley fog reports for Port Angeles and the Elwha valley — if both are reporting dense fog with calm winds and a clear sky above 1,000 meters, Hurricane Ridge will be above it all at dawn.



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.
