Weather in August
Temperature
The shift from July to August is characterized by an average high-temperature of a still hot 89.1°F (31.7°C), not significantly different from the 89.6°F (32°C) of July. Saint Rose throughout August, records an average low-temperature of 77.5°F (25.3°C).Heat index
The heat index value during August is calculated to be a blistering 107.6°F (42°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Consider that heat index readings are for situations in the shade and light wind. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. 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 extremely significant for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. Opt for tightly woven and loose clothing to enhance protection from the Sun.
