Weather in August
Temperature
During August, Mayport observes a subtle ascent to a still tropical 88.9°F (31.6°C) from July's 89.2°F (31.8°C) in the average high-temperature. In Mayport, the August nights cool down to an average low of 78.3°F (25.7°C).Heat index
In August, the heat index is computed to be a blistering 105.8°F (41°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', arises from combining readings of air temperature and relative moisture content. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. 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.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
