Know before you drive: FogCast checks the conditions that produce photogenic fog
Get more than a snapshot of current conditions. The LightCast app unlocks everything to plan ahead
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.
Set a FogCast threshold once. The app will alert you when conditions at your saved locations look promising, so you're not manually checking at 4am.
Don't waste a sunrise drive. Check FogCast before you leave.

The contrast between the cloud-draped north coast and the sunnier south is one of the defining features of the island's climate. In the high interior, particularly around Pico do Arieiro and the Laurisilva cloud forest, fog is present on most days of the year.
The Pico do Arieiro and Pico Ruivo ridge — the highest terrain on the island at 1,700 to 1,800 meters — offers above-cloud photography when the trade wind inversion sits between 1,200 and 1,600 meters. From these ridges, the northern slopes of the island disappear into a white sea of cloud while the summit rocks are clear and sunlit. Early morning is most reliable before the cloud layer deepens. The Levada do Caldeirão Verde trail through the Laurisilva forest is exceptional for low-level fog photography among the ancient laurel trees.
Madeira fog is largely orographic — it forms when moist Atlantic air is forced upward by the island's topography and cools to the dew point. The trade wind inversion height is the key variable: when the inversion sits between 1,200 and 1,700 meters, the summit ridges are above cloud and the fog photography from the peaks is at its best.
