Weather in August
Temperature
The average high-temperature in August, at a warm 84.9°F (29.4°C), reveals a modest deviation from July's 86.2°F (30.1°C). In August, Leamington experiences an average nighttime temperature of 66.2°F (19°C).Heat index
For August, the heat index is calculated to be a torrid 95°F (35°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Understand that the heat index values take into account shaded locations and mild winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Take precautions against overexposure. Protection against sun damage is needed. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
