Weather in August
Temperature
The weather during August records an average high-temperature of a still hot 86.7°F (30.4°C), closely mirroring the preceding month. Cainhoy experiences an average low-temperature reading of 77.4°F (25.2°C) throughout August.Heat index
August's heat index is estimated at a torrid 100.4°F (38°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Metrics for the heat index primarily focus on shaded spots and light wind conditions. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Resist extreme sun exposure. Guarding against solar damage is essential. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
