Weather in August
Temperature
The transition into August reveals an average high-temperature of a still moderately hot 81.7°F (27.6°C), mirroring a close resemblance to July. During the month of August, the temperature generally drops to a low average of 63.5°F (17.5°C).Heat index
Throughout August, the heat index is computed to be a tropical 87.8°F (31°C). Remaining active during long-lasting exposure could cause fatigue, leading to heat cramps.Note that heat index values are valued for light wind and location in the shade. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
