Most people understand relative humidity, but the dew point is a much better measure of how humid it really feels.

We’ll be discussing the difference between dew point and relative humidity in this edition of Weather Tidbits. Both of these ...

Often times during hot and humid stretches of the summer season you’ll hear a meteorologist refer to the dew point temperature, but not so much the relative humidity. And that may have you ...

While 100 percent humidity might seem to suggest there should be pure rain showers, there may not even be a hint of drizzle.

There’s a good reason as to why. First, let’s define the two terms. Relative humidity is a measure of how saturated the air is relative to how much moisture it can hold.

A new study reveals that hot and humid days can increase the risk of heart-related emergencies by six times compared to hot ...

Not at all. Relative humidity is best used when comparing the rate of evaporation. An example is taking a droplet of water and running it through a parcel of air that has a temperature of 40 degrees.

High humidity is the main factor for oppressive conditions and is driven by the amount of moisture in the air. We can measure the moisture content of air by recording the dewpoint temperature.

It’s a blend of the air temperature and relative humidity percentage, and it shows what the temperature outside actually feels like to the human body. So, it’s not just the humidity that gets you.

According to the National Weather Service, the dew point is the temperature where the air needs to be cooled to, at constant pressure, in order to achieve a relative humidity (RH) of 100%.

Dew point vs. relative humidity The short answer is both terms are different and describe different things about moisture in the air. The dew point is another temperature value.
