Weather in August
Temperature
The transition into August notes an average high-temperature of a moderately hot 84.9°F (29.4°C), revealing a mild distinction from the 86°F (30°C) in July. Marked by a significant temperature drop from daytime highs, the average nighttime temperature lowers to an enjoyable 62.4°F (16.9°C) throughout August.Heat index
The average heat index in August is appraised at a very hot 95°F (35°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.One should consider that heat index numbers are for shaded settings and light wind. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
