Weather in August
Temperature
The arrival of August coincides with an average high-temperature of a still moderately hot 83.1°F (28.4°C), indicating a minimal shift from July's 85.3°F (29.6°C). Throughout the month of August, the nighttime temperature dips to an average of 66.9°F (19.4°C).Heat index
August's average heat index is evaluated at a hot 89.6°F (32°C). With unrelenting exposure and activity, one might experience exhaustion, leading to potential heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
