Weather in August
Temperature
Stepping into August, Slate records an average high-temperature of a still warm 81.7°F (27.6°C), almost consistent with July. The nighttime temperature during August exhibits a clear drop from daytime highs, settling at a mild 57.7°F (14.3°C).Heat index
August's heat index is appraised at a hot 87.8°F (31°C). If one continues to be active during exposure, it might cause tiredness and subsequent heat cramps.Heat index determinations are made taking into account the shade and light air movements. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', unifies temperature and humidity readings to offer a comprehensive feel of warmth. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
