Weather in August
Temperature
August's advent denotes a minor fluctuation in the average high-temperature to a still moderately hot 82.9°F (28.3°C) from July's 84.7°F (29.3°C). In August, the average low-temperature is a comfortable 65.7°F (18.7°C).Heat index
Throughout August, the heat index is appraised at a hot 87.8°F (31°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Given the heat index, its values are aligned with shaded sites and gentle winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
