Heat index

September's mean heat index is calculated to be a burning hot 59°C (138.2°F). Warning: These weather conditions are assessed as supremely perilous, heatstroke is imminent.
One should consider that heat index numbers are for shaded settings and light wind. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.

Also note that objects like parasols or canopies might not provide complete sun protection. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears. Ensure the liberal application and reapplication of a broad-spectrum SPF 30+ sunscreen after each outdoor activity or swim, and every two hours. Caution! The Sun's UV rays become stronger due to reflections from water and sand.
