Weather in August
Temperature
The dawn of August sees an average high-temperature of a still moderately hot 83.3°F (28.5°C), subtly contrasting with July's 85.5°F (29.7°C). A considerable shift from the daytime highs is observed during August nights, with an average low of 61.2°F (16.2°C).Heat index
In August, the heat index is evaluated at 82.4°F (28°C). If exposure and activity are sustained, they might cause a feeling of weariness, resulting in heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. 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.
