Weather in August
Temperature
The arrival of August coincides with an average high-temperature of a tropical 93°F (33.9°C), indicating a minimal shift from July's 95.2°F (35.1°C). During the nights in August, an average low-temperature of 72.9°F (22.7°C) is observed.Heat index
The average heat index in August is computed to be an extremely hot 104°F (40°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. 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 important for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
