Heat index

The heat index in August is appraised at a torrid 96.8°F (36°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Experience reduced UV exposure by about half when donning a wide-brim hat. Beware! The reflection of water and sand dramatically increases exposure to the UV rays.
