Weather in August
Temperature
The shift into August uncovers an average high-temperature of a still warm 83.7°F (28.7°C), subtly different from the previous month. Throughout August, an average nighttime temperature of 67.5°F (19.7°C) is experienced.Heat index
The heat index for August is appraised at a hot 89.6°F (32°C). If exposure and activity are sustained, they might cause a feeling of weariness, resulting in heat cramps.Records show heat index calculations are tailored for shaded regions and mild winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant 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.
