Weather in August

Continued action may cause heatstroke.One should consider that heat index numbers are for shaded settings and light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', marries air temperature and humidity to produce a value illustrating perceived warmth. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
