Weather in August
Temperature
August registers an average high-temperature of a still moderately hot 81.5°F (27.5°C), slightly varied from July's 82.6°F (28.1°C). August nights experience a consistent temperature drop to a refreshing 63.5°F (17.5°C).Heat index
Throughout August, the heat index is computed to be a tropical 87.8°F (31°C). Continuing activity during long-lasting exposure might induce tiredness and result in heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', gauges the sensation of temperature factoring in the air's moisture content. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
