So in general, regarding perishable foods like meat, most dairy, unshelled eggs and shell eggs (in the US) , cooked casseroles, and so on: if the food (or its perishable components) have been at room temperature for more than two hours, you should discard that food.
This directly effects how comfortable it will feel outside. Many times, relative humidity can be misleading. For example, a temperature of 30 and a dew point of 30 will give you a relative humidity of 100%, but a temperature of 80 and a dew point of 60 produces a relative humidity of 50%.
North Florida and the Panhandle have average dew points of 40 to 50 and south Florida has winter dew points of 55 or higher. Common Myths Boy it's hot and humid today..., it must be 95 degrees outside with 95% humidity.
