Heat index
In April, the heat index is calculated to be a blazing hot 53°C (127.4°F).
Guard: Heat exhaustion and heat cramps are foreseeable. Prolonged effort may bring about heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a measure of how hot it feels when the actual air humidity is factored in. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Rising body temperatures due to excess heat retention could signify impending heat disorders.
Humidity
In April, the average relative humidity is 57%.
