When the temperature goes up and the humidity is high, we feel uncomfortable. Everyone is affected differently, and people used to high heat and humidity will not be as uncomfortable as those not used to this type of weather. The elderly and very young are most susceptible to heat stress. By using this chart, you can get a general idea of how hot the temperature may feel to you.

Subtract 2° from the heat index temperature if the wind speed is 11-15 mph and 4° if the wind is between 16 and 20 mph. Blank boxes represent weather conditions that are highly unlikely, if not impossible. You can protect yourself from heat stress or heat stroke by following some simple rules in hot, humid weather: Dress for comfort but protect yourself from the sun. Light-colored clothing is best. Drink fluids to prevent dehydration even if you are not particularly thirsty. Avoid alcohol. Carbonated drinks are not recommended. Water is best. Get out of the sun if you feel dizzy and stop sweating. Put a cold, moist towel around your neck. If these symptoms persist, seek medical attention immediately.
