Weather in August
Temperature
August notes an average high-temperature of a still warm 81.3°F (27.4°C), subtly differing from July's 83.1°F (28.4°C). Nightly temperatures drop to an average low of 62.6°F (17°C) in August.Heat index
The heat index for August is appraised at a hot 87.8°F (31°C). Staying active during long-term exposure might result in a state of exhaustion and cause heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
