Also record how the weather feels to you. Record the actual temperature and the relative humidity. Over the course of a few weeks, keep a daily weather log. Can you really feel the difference when relative humidity fluctuates? Keep track and see for yourself.As the humidity lowers, the air feels cooler!

When water vapor remains in the air as humidity, it makes the temperature feel warmer. When you waved the washcloth around in the air, water evaporated from it, taking heat with it and making the washcloth cooler. As moisture evaporates, it carries heat with it. When you're finished, feel the washcloth again. Now wave the washcloth around in the air for a bit. Wring out the water so that none drips out but the washcloth is still warm. Soak a washcloth in a bowl of warm water. Here's a little experiment that will help you understand why. You've probably felt how a hot day can feel even hotter when it's really humid outside.Do you understand all the weather-related terms the forecasters use? If not, ask an adult to help you understand what any unfamiliar terms mean. Or, if you prefer, you can read them in a local paper or even find them online at a variety of weather information sites. You can watch them on television on the nightly news. Spend some time watching local weather forecasts.Ready to get some hands-on experience with humidity? Find a friend or family member to help you explore one or more of the following activities: Some people use special machines called humidifiers (add humidity) or dehumidifiers (remove humidity) to keep indoor humidity at a comfortable level. So what's a comfortable humidity level? Studies have shown that we tend to feel most comfortable at a relative humidity of around 45%. On the other hand, a relative humidity of 100% would make it feel like it's 80° F (26.6° C). A relative humidity of 0% would make it feel like it's only 69° F (20.5° C). If the temperature outside is 75° F (23.8° C), humidity can make it feel warmer or cooler. This happens because the dry air helps sweat evaporate more quickly than usual. Likewise, very low humidity can make us feel cooler than the actual temperature.

When this happens, we feel hotter than the actual temperature. If the relative humidity is very high, the air is already saturated with water vapor and our sweat won't evaporate.

So how does humidity affect us on a hot day? Humans are sensitive to changes in humidity, because our skin uses the air around us to get rid of moisture in the form of sweat. However, at ground level where the rain lands, the relative humidity can be less than 100%. In fact, the relative humidity must be 100% where clouds are forming for it to rain. Relative humidity is the term weather forecasters use most often.Ī relative humidity of 100% means that the air can't hold any more water vapor. Relative humidity is the ratio of the current absolute humidity to the highest possible absolute humidity, which will depend upon the current air temperature. The hotter the air is, the more water vapor it can hold. Absolute humidity is the amount of water vapor divided by the amount of dry air in a certain volume of air at a particular temperature. When you hear weather forecasters talk about humidity, you may hear them talk about two different terms: absolute humidity and relative humidity. Could you imagine life without clouds, rain, snow, thunder, or lightning? Without water vapor in the air, our weather might be like the weather on Mars. Humidity plays an important role in our daily weather. For example, high humidity combined with hot temperatures is a combination that can be a health risk, especially for the very young and the very old. Too much or too little humidity can be dangerous. Humidity is the amount of water vapor in the air. Most of the air around you has water in the form of a gas called water vapor. To understand humidity, you first have to realize that there's water in the air all around you. “It's not the heat, it's the humidity!' Have you ever heard someone say that on a warm, muggy day? As you'll see soon, there's a lot of truth in that statement.
