Weather in August
Temperature
August's commencement is accompanied by an average high-temperature of a still hot 90.9°F (32.7°C), diverging marginally from July's 91.4°F (33°C). An average low-temperature of 70.3°F (21.3°C) is anticipated throughout the nights during August.Heat index
For most parts of August, the heat index is estimated at a blistering 105.8°F (41°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. 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 vital to babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. 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. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
