Heat index

September's mean heat index is evaluated at a torrid 102.2°F (39°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. 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 for babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
