Here’s how lower humidity can make the heat more bearable

ORLANDO, Fla. – A rare summer cold front is heading to Central Florida.

While we don’t usually expect cool temperatures in summer, this front is strong enough to lower the humidity, making the heat more bearable.

During summer, meteorologists often talk about the heat index or “feels like” temperatures, which takes into account air temperature, humidity and wind at about 5 feet above the ground. This “feels like” temperature can refer to heat index, wind chill or how other factors, like direct sunlight, affect how hot or cold it feels.

Understanding the “feels like” temperature helps you know how the weather will feel on your body. It gives a better idea of what to expect compared to just the air temperature.

How are humidity and dew point temperatures related?

The dew point is the temperature where air becomes fully saturated with moisture.

When the air temperature is close to the dew point, humidity is high. When the air temperature is much higher than the dew point, humidity is lower.

So a higher dew point means higher humidity, and a lower dew point means lower humidity.

Yes, lower humidity can make heat feel less oppressive compared to high humidity, but it doesn’t necessarily mean that you let your guard down.

Here’s why:

• Evaporation: With lower humidity, sweat evaporates faster, helping your body cool down better and making the heat feel less severe.
• Heat Index: The heat index, which shows how hot it feels when you factor in both temperature and humidity, is lower in dry conditions. This makes the heat more manageable than in high humidity.
• Hydration and Health: Even if the heat feels less oppressive, you still need to stay hydrated and be careful. High temperatures can still lead to heat-related problems if you’re not drinking enough water or overexerting yourself.
• Individual Differences: People with health issues or who aren’t used to hot weather might still suffer from heat stress even in lower humidity.

While lower humidity can ease some of the discomfort, it’s important to take precautions to stay safe in the heat.
