Fog is basically visible water particles in the air. One of my sensors outside measured the humidity with the fog, I came out with 95% - 100%.

When the temperature equals the dew point, the air is saturated and the relative humidity is 100%. This means that the air cannot hold any more moisture at that specific temperature and any further cooling will result in condensation, such as fog or dew formation.
condense
When air reaches its dew point, the relative humidity is 100%. At this point, the air is saturated with moisture and can no longer hold additional water vapor, leading to condensation and the formation of dew or fog.

To experience fog an area has to have a relative humidity of near or at 100%. The temperatures must be at or near the dew point. Deserts rarely have the humidity levels needed to produce fog.
The relative humidity is very high today. It is the fraction of water vapor in the air expressed as a percentage of the level where it condenses to a fog.
Relative Humidity goes above 90%, that means there is dew or fog forming or has formed. Related Links will give you more information.
Yes, fog occurs at 100% relative humidity, meaning the air is fully saturated with water vapor. When the air temperature drops to the dew point, tiny water droplets condense, creating fog. This saturation is necessary for fog formation, as it indicates that the air cannot hold any more moisture in vapor form.
The air is holding as much water as it can. It will frequently be heavy fog or raining.
When the relative humidity reaches 100%, it is known as the dew point. At this point, the air is saturated with moisture, leading to condensation and potentially fog, dew, or precipitation.
When the air temperature reaches the dew point, water droplets that are in the air become visible. This is how you would get fog. Relative Humidity goes soaring to near 100%.
