In September, the average heat index is appraised at a tropical 91.4°F (33°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
