Weather in August
Temperature
August, having an average high-temperature of 81°F (27.2°C) and an average low-temperature of 53.4°F (11.9°C), is the warmest month.Heat index
The average heat index in August is estimated at 84.2°F (29°C). With ongoing exposure and activity, one might experience weariness, and heat cramps could ensue.Understanding the heat index involves considering values for shaded locales with light wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection.
