Weather in August
Temperature
August, noted for its average high-temperature of 94.6°F (34.8°C) and an average low-temperature of 74.3°F (23.5°C), is considered the warmest month.Heat index
Throughout August, the heat index is calculated to be a burning hot 113°F (45°C). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', gives a temperature feeling by integrating air temperature and humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
