Weather in August
Temperature
The months of July and August bring the highest temperatures, averaging a high of 29.3°C (84.7°F).Heat index
The average heat index in August is evaluated at a sweltering 36°C (96.8°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
