Weather in August
Temperature
August's arrival brings an average high-temperature of a still hot 86.5°F (30.3°C), slightly deviating from July's 88.5°F (31.4°C). During the month of August, the temperature falls to an average of 65.5°F (18.6°C).Heat index
Throughout August, the heat index is estimated at a very hot 98.6°F (37°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
