During September, the heat index is computed to be a hot 31°C (87.8°F). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.Know that the heat index computations account for shaded terrains and slight winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. 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. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
