Weather in August

Entering August, the average high-temperature is recorded at a still hot 88.2°F (31.2°C), exhibiting a minimal shift from July's 88.9°F (31.6°C). Significant dips from daytime highs mark the August nights in Brighton, with a consistent average temperature of 60.4°F (15.8°C).Heat index
Throughout August, the heat index is computed to be a tropical 87.8°F (31°C). Uninterrupted exposure and activity might result in fatigue, potentially causing heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
