The temperature tends to be higher on foggy days because of the precipitation in the air causing the air to be thicker and thus conducting heat better.

Foggy days are usually preceded by foggy nights. The fog at night keeps in the heat and does not allow temperatures to fall much during the night. Then during the day if it is still foggy the temperature is warmer because you are starting out at a higher temperature in the morning.

This is true in some regions, cloud act like a cap or cover and retain heat.
Outer space is at on an average about -4 degrees Centigrade.
When flying at high altitude(37,000 ft.) Pilots may says out side temperature is about, -30 degrees centigrade I have heard this even in summer.

Its not the fog that keeps it warm, but the cloud cover. Fog develops if the temperature is below the dewpoint. Cloudy weather keeps the earth insulated and warm like a blanket. I have seen many cold days with fog and many warm days with fog. The low pressure and humidity creates cloudy and rainy weather.

When warm air passes gently over colder sea or land surface the air in contact gets cooled. if the air is cooled below its dew point water is released from air. the water droplets settle on the dust particles, salt or the pollutants and remain suspended in air as they are very small and light. this is fog.
Also as the moisture is released the latent heat is released leading to warming of the air. Thus condition for formation of fog is warm air, and after formation further heating by release of latent heat.

this is because of the greenhouse effect. The hot air has not much place to escape into the atmosphere and so it is around the earh's surface and thats why the temperature is more.

since fog is greenhouse gas, it traps the sun's heat thus resulting in increase of temperature near the earth's surface

The fog layer traps the sun's warmth beneath it.

Could be that the ground is colder than the air thus causing fog.

All the previous answers, plus it may just feel warmer because of the increased humidity.
