Heat index

August's mean heat index is appraised at a very hot 102.2°F (39°C). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. 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 primarily vital for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
