The state that is always foggy is Washington which is the most overcast state in the Union and has 165 foggy days a year on average.

The season that has the most fog is fall and winter and it forms overnight or in the early morning when the ground cools and stabilizes and when the air is cool.

The foggiest place on Earth is the Grand Banks that lies off the cost of Newfoundland and the area forms the meeting place of the cold Labrador Current from the north and the much warmer Gulf Stream from the south.

Fog is a cloud that touches the ground and forms when air near the ground cools off enough to turn it's water vapor into liquid water or ice.

Fog is worse in the day and in the morning which is when the fog is at thickest because the morning is the coolest part of the day when the temperatures drops to the dew point and the relative humidity approaches 100 percent.

The time of day that fog is most common is in the morning just before sunrise or it can also occur during sunrise or at sunset.

Fog most often occurs in the morning because the morning is the coolest time of day when the temperature drops to the dew point temperatures and the relative humidity approaches 100 percent.

Most fog will completely go away and dissipate within a few hours after sunrise.

The difference between fog and mist is how far you can see through them.

Fog is when you can see less than 1,000 meters or 0.62 meters away and if you can see further than 1,000 meters or 0.62 miles away then it's mist.

Fog is also when microscopic droplets reduce the horizontal visibility at the Earth's surface to less than 0.62 miles and mist is when droplets do not reduce the horizontal visibility to less than 0.62 miles.

Mist is considered synonymous with light fog.

The temperature at which fog forms is any air temperature and dew point that is less than 4.5 F.

The fog begins to form when the water vapor condenses into tiny water droplets which are suspended in the air.

The main cause of fog is water vapor or water in it's gaseous form condensing.

During condensation, the molecules of water vapor combine to make tiny liquid water droplets which hang in the air.

And because of the tiny water droplets you can see the fog.

The water vapor itself is a gas that is invisible.

And steam fog forms when cold air moves over warm water.

When the cool air mixes with the warm moist air over the water, the moist air cools until its humidity reaches 100% and fog forms.

Warm air, air blows in from the south and if there is snow or cool moisture on the ground it will come in contact with the warm, moist winds.

This contact between the air and ground will cause the air blowing in to become cool.

Then dew point rises and creates high humidity and forms fog.

Fog normally occurs at a relative humidity near 100%.

This occurs from either added moisture in the air, or falling ambient air temperature. However, fog can form at lower humidity, and can sometimes fail to form with relative humidity at 100%.
