Heat index

September's heat index is calculated to be a very hot 38°C (100.4°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical to babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays.
