Weather in August
Temperature
The commencement of August records an average high-temperature of a still moderately hot 83.5°F (28.6°C), barely varying from July's 84°F (28.9°C). Throughout August, an average low-temperature of 64.9°F (18.3°C) is expected.Heat index
Throughout August, the heat index is calculated to be a hot 91.4°F (33°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for 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.
