Weather in August
Temperature
The arrival of August brings an average high-temperature of a still moderately hot 82°F (27.8°C), closely following the temperature pattern of July. Witt temperatures generally rest at a low of 64.9°F (18.3°C) during the August nights.Heat index
In August, the average heat index is calculated to be a hot 89.6°F (32°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.Research indicates the heat index considers values in shaded locales and with light winds. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. 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 of high significance for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
