Heat index

The heat index value for September is computed to be a torrid 35°C (95°F). Undertake additional safety actions, risk of heat cramps and heat exhaustion is significant. Persistent activity may induce heatstroke.
One should consider that heat index numbers are for shaded settings and light wind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Carry out all important precautions, unprotected skin could get burns in no time. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Clothes that are both tight-knit and comfortably loose are prime choices for sun protection. Even on overcast days, a sunscreen with a sun protection factor of no less than 30 should be generously applied and reapplied, particularly after swimming or outdoor activities. Heads up! UV intensity is amplified by reflections from water and sand.
