Weather in August
Temperature
August ushers in an average high-temperature of a still moderately hot 83.5°F (28.6°C), aligning closely with the preceding month. A stark contrast in day to night temperatures can be seen in Acton in August, with an average low-temperature of 60.6°F (15.9°C).Heat index
The heat index for August is appraised at 82.4°F (28°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', reflects the blend of air temperature and relative humidity to give a temperature impression. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. 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.
