Weather in August
Temperature
August registers an average high-temperature of a still tropical 91.4°F (33°C), slightly varied from July's 92.7°F (33.7°C). Altus reports a steady low-temperature average of 68.5°F (20.3°C) throughout August, revealing a large deviation from the daytime high.Heat index
The heat index value during August is evaluated at an extremely hot 111.2°F (44°C). Watchful: Heat cramps and heat exhaustion are predicted. Continued exertion could lead to heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'feels like', 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. 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 are especially crucial for babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Stay clear of intense sun exposure. Solar protection is of utmost significance. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
