Weather in August
Temperature
The dawn of August sees an average high-temperature of a still tropical 89.1°F (31.7°C), subtly contrasting with July's 90.3°F (32.4°C). Grayson records an average low-temperature of 70.2°F (21.2°C) throughout the month of August.Heat index
The heat index in August is evaluated at a scorching 104°F (40°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Note that heat index values are valued for light wind and location in the shade. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical 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.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Persist with precautions and heed sun safety advice. Prevention of sunburn is compulsory. 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 shield, deflecting up to 50% of harmful UV radiation from eyes.
