Dangerous heat likely for rest of June in the SC Lowcountry. Here’s what to expect
It’s been a hot and sweaty June so far, and temperatures won’t relent much as the month goes on.
Temperatures were in the 90s the last several days. The National Weather Service advises caution in temperatures that high. And summer hasn’t officially started yet. It begins on the summer solstice, June 21.
Forecasters predict a slight decrease in temperature for the rest of June. But with high humidity, temperatures may feel much higher. Here’s the temperature outlook:
SC Lowcountry temperatures
AccuWeather forecasts the highest temperature for the remainder of June at 92 to 93 degrees. Last Saturday, Beaufort County experienced a high around 95. The average high for June is 88 degrees according to AccuWeather.
Temperatures won’t exceed 88 degrees this week. Starting Sunday and continuing through next Tuesday, temperatures will be in the low 90s. The peak temperature will be on Tuesday, June 23 at 92 degrees in Hilton Head and 93 degrees in Beaufort.
Heat Index
Humidity increases how hot temperatures feel to the human body. Humidity decreases the evaporation of sweat from the body, making it harder to cool down.
Forecasters use a combination of humidity and temperature to determine the heat index, or the temperature you feel. On a 90 degree day with 100% humidity, the heat index would be 132 degrees.
Beaufort County’s waterways and the Atlantic Ocean bring moisture to the air and as a result, higher humidity. Even if the temperature is lower, it can still be dangerously hot.
The NWS urges caution in heat index temperatures above 80 degrees. A heat index above 90 degrees can cause heat stroke with prolonged exposure. Heat stroke is highly likely at a heat index above 125 degrees.
To avoid heat stroke, NWS recommends avoiding strenuous outside activities, staying in the shade and staying hydrated. Don’t leave children or pets unattended in your car. Car interiors can quickly reach temperatures far above the outside temperature when in direct sunlight.
