Fog and haze are not the same
Fog is cloud in contact with the ground, while haze can reduce visibility without producing the same dense local effect.
Low cloud on the slopes
A lakeside location can remain below the cloud base while mountain routes are immersed in cloud. This is particularly important for hiking and viewpoints.
Navigation
Reduced visibility changes the practical risk of boating. Check actual conditions as well as forecasts before leaving and maintain appropriate safety margins.
