Did you know?

The dew point is technically the air temperature that must be reached for “dew” to form. In other words, the air is saturated. The interesting part about “humidity,” often times humidity is actually higher in the wintertime. We can not feel that humidity as much in the wintertime because of the air temperature. The colder the temperature, the lower amount of water vapor that can be held and the warmer the air temperature, the more water vapor that can be held.

Let me explain a little bit more:

Imagine you have a marshmallow… if you place it in your freezer, you notice the marshmallow shrink. The marshmallow now has a smaller volume (or covers less space), which means it will be able to hold less water.

Now, what if you put another marshmallow in the microwave? The marshmallow would expand, leading to an increasing volume (or increased space). This would be able to hold more water.

The more water that a molecule can hold, the more you will be able to feel humidity.

So if the temperature is warmer, the dew point can be higher. This in turn means the higher the dew point, the more humid it will feel. So, next time you hear the dew point is going to be in the mid-60s, you know that it is going to be a muggy day.

So what is the Dew point today?
