Weather in August
Temperature
August begins with an average high-temperature of a still tropical 93.4°F (34.1°C), reflecting close similarity to the preceding month. Rosemont documents a substantial shift from daytime warmth, recording an average nighttime temperature of 59.9°F (15.5°C) in August.Heat index
In August, the average heat index is appraised at a sweltering 98.6°F (37°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.The standards for the heat index are set for locations in shade and under light breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
