Weather in August
Temperature
August, with its average high-temperature of 81°F (27.2°C) and an average low-temperature of 54°F (12.2°C), holds the record as the warmest month.Heat index
Throughout August, the heat index is evaluated at 84.2°F (29°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
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. 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. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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.
