National Heat Awareness Day

In case your melting shoe soles and sticky jeans need a reminder that heat is in full swing in South Texas - In observance of National Heat Awareness Day (May 25, 2012), NOWCastSA and Community First Health Plans want to encourage everyone to gulp down water, take siestas in the shade, and never leave children, pets or elderly people in a parked vehicle.

According to the National Weather Service, on average, heat claims more lives per year than floods, lightning, tornadoes, and hurricanes combined. Read more here.


While your scalp may disagree, the season for frying eggs on city sidewalks is still not due for another month. Thats right, the first official day of summer isn't until Wednesday, June 20. Ladies and gentleman, prepare yourselves for a scorcher!

For people in Bexar County, heat and humidity go hand in hand like salt and lime on a Dosarita. Like the latter, too much of the mixture can have you stumbling through the street, only worse. 

While our city bakes under intense heat, the humidity manipulates how hot it really feels. This temperature is referred to as the heat index. Put differently, on National Heat Awareness Day in San Antonio, the air temperature was 94°F and the relative humidity was 45%, the heat index--how hot it felt--was 100°F. See chart below.
