Weather in August
Temperature
The advent of August brings an average high-temperature of a still hot 90.5°F (32.5°C), almost identical to the preceding month. Onward, during the nights of August, experiences an average temperature drop to an agreeable 72.3°F (22.4°C).Heat index
August's heat index is calculated to be a scorching 111.2°F (44°C). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.Given the heat index, its values are aligned with shaded sites and gentle winds. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
