Heat index

For September, the heat index is evaluated at a blisteringly hot 43°C (109.4°F). Warning: Heat cramps and heat exhaustion are anticipated. Heatstroke is a risk with ongoing activity.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Never be careless. Unprotected skin and eyes can be harmed swiftly. 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. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
