In September, the heat index is computed to be a tropical 86°F (30°C). With constant exposure and activity, a state of weariness might ensue, leading to potential heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. 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.
