Heat index

For most parts of August, the heat index is calculated to be a blisteringly hot 109.4°F (43°C). Note: Heat exhaustion and heat cramps are probable. Heatstroke can follow with prolonged activity.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
