Weather in August
Temperature
August commences with an average high-temperature of a still moderately hot 81.1°F (27.3°C), showing little deviation from July's 82.4°F (28°C). Nightly readings in August display a noticeable downturn from daily highs, with the average low-temperature registering a moderate 58.5°F (14.7°C).Heat index
August's average heat index is evaluated at 80.6°F (27°C). Persisting in activity during exposure could lead to weariness and subsequently to heat cramps.Always consider that heat index estimations are for light winds and places in the shade. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
