Weather in May
Temperature
With the onset of May, Saint Elmo experiences a subtle temperature shift, with the average high-temperature moving from a moderately hot 76.5°F (24.7°C) in April to a still warm 82.9°F (28.3°C). May nights cool down to an average low-temperature of 69.1°F (20.6°C).Heat index
The heat index for May is evaluated at a hot 89.6°F (32°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
