Weather in August
Temperature
August brings an average high-temperature of a warm 85.5°F (29.7°C), showing a slight difference from July's 86.7°F (30.4°C). August nights are marked by an average temperature drop to a comfortable 67.1°F (19.5°C).Heat index
In August, the average heat index is appraised at a sweltering 95°F (35°C). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', determines the feeling of heat when you account for the relative humidity. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
