Weather in August
Temperature
The warmest month is August, with an average high-temperature of 29.6°C (85.3°F) and an average low-temperature of 13.5°C (56.3°F).Heat index
August's heat index is appraised at a hot 32°C (89.6°F). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Always consider that heat index estimations are for light winds and places in the shade. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to 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.
