Weather in August
Temperature
The introduction of August notes a subtle temperature variation to a still warm 82°F (27.8°C) from July's 84°F (28.9°C). Nighttime temperature lowers to an average of 63.1°F (17.3°C) in August.Heat index
In August, the average heat index is estimated at a hot 87.8°F (31°C). With prolonged exposure and constant activity, one might feel exhausted and experience heat cramps.One should consider that heat index numbers are for shaded settings and light wind. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. 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.
