Weather in August
Temperature

Persistent activity may provoke heatstroke.Observations indicate that the heat index values are for shady locations with light wind. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is achieved by amalgamating air temperature with the relative humidity readings. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
