Heat index

In August, the average heat index is estimated at a life-threatening hot 45°C (113°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
The heat index's values are generally associated with conditions in shade and light breezes. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical for babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. With higher relative humidity, the rate of evaporation is reduced, resulting in increased heat retention in the body compared to drier air. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Humidity

The average relative humidity in August is 64%.

Take precautions against overexposure. Fair-skinned people may get burned in less than 20 minutes. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
