Heat index

The heat index value during September is estimated at a very hot 37°C (98.6°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. 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 physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Note: The UV index of 6 in September translates into these instructions:
Deter overexposure. Protecting against the sun's effects is essential. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
