Weather in August
Temperature
The arrival of August marks a slight shift to an average high-temperature of a still warm 81.7°F (27.6°C) from July's 82.8°F (28.2°C). August's average low-temperature reading settles at a refreshing 64°F (17.8°C).Heat index
Throughout August, the heat index is estimated at a tropical 87.8°F (31°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is achieved by amalgamating air temperature with the relative humidity readings. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
