Weather in August
Temperature
August is the month when Francis experiences its warmest temperatures, averaging a high of 91.9°F (33.3°C) and a low of 75.4°F (24.1°C).Heat index
August's mean heat index is estimated at a blazing hot 118.4°F (48°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
