Weather in August
Temperature
The beginning of August records an average high-temperature of a still warm 81.1°F (27.3°C), marking a negligible difference from July's 82.9°F (28.3°C). An average temperature of 64.9°F (18.3°C) is recorded during the nights in August.Heat index
In August, the average heat index is computed to be a tropical 86°F (30°C). If one continues to be active during exposure, it might cause tiredness and subsequent heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
