Weather in August
Temperature
The onset of August marks an average high-temperature of a still warm 83.5°F (28.6°C), hardly differing from July's 85.6°F (29.8°C). During the August nights, an average temperature of 67.3°F (19.6°C) is observed.Heat index

Uninterrupted exposure and activity might result in fatigue, potentially causing heat cramps.It is essential to grasp that the heat index's numbers are for shade and light wind settings. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
