Weather in August
Temperature
August's onset brings an average high-temperature of a still warm 82.4°F (28°C), showing a minute difference from July's 83.5°F (28.6°C). The month of August sees a significant daily temperature drop, recording an average low-temperature of 58.6°F (14.8°C).Heat index
For August, the heat index is computed to be a tropical 89.6°F (32°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
