Weather in April
Temperature
The shift into April is accompanied by a modest temperature increase, with the average high-temperature edging up from a warm 78.6°F (25.9°C) in March to a still moderately hot 84.4°F (29.1°C). Throughout the month of April, Charleston Park observes an average nighttime temperature of 65.8°F (18.8°C).Heat index
During April, the heat index is evaluated at a hot 91.4°F (33°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant 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.
