Weather in August
Temperature
August registers an average high-temperature of a still moderately hot 81.1°F (27.3°C), slightly varied from July's 82°F (27.8°C). August nights are marked by an average temperature drop to a refreshing 63.9°F (17.7°C).Heat index
The heat index value during August is computed to be a hot 87.8°F (31°C). Exhaustion is likely with prolonged exposure and activity. Sustaining activity may result in heat cramps.Know that the heat index computations account for shaded terrains and slight winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, 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 essentially critical for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
