Weather in August
Temperature
August's advent denotes a minor fluctuation in the average high-temperature to a still moderately hot 80.6°F (27°C) from July's 81.1°F (27.3°C). During August, the nighttime temperature averages of 63.3°F (17.4°C).Heat index
The heat index in August is estimated at a tropical 86°F (30°C). Constant activity during exposure could result in a state of weariness and possibly heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
