Dense Fog

Dense fog occurs during every month of the year in Wisconsin.  It is more common during the cooler months of September through April. During the fall and spring months, dense fog favors the early morning hours, while during the winter months, dense fog can occur just about any time if certain weather conditions come together.  Sometimes the dense fog becomes widespread and lowers visibilities to less than 1/4 mile, or even down to near zero, when they then become a deadly traffic hazard.

Driving Safety Tips:
  • Headlights should be on low beam.  This allows other drivers to see you.
  • Yellow fog lights are also helpful because they have less glare.
  • Motorists should drive slower and allow for extra time in reaching destinations.
  • Motorists should increase their following distances behind the vehicle in front of them.
  • Always assume there could be stopped traffic in front of you.
  • Listen to the latest forecast on NOAA weather radio, or commercial radio or TV or cable TV before leaving on a road trip.
  • Postpone a road trip when dense fog is forecast to reduce visibilities to near zero.
