Why is Iceland foggy?

Influenced by the North Atlantic warm current, it mainly flows out from its south, and there is a branch around its west and north.

The ocean brings rich water vapor, which makes Iceland rainy and foggy.

Located near the center of low pressure in Iceland, the weather is changeable. Cyclones have brought abundant precipitation to Iceland. The annual average precipitation in southwest and west is between 1000 ~ 2000mm, and it is less in north and northeast, which is 400 ~ 600 mm. Rain and snow weather may occur in any season.
