Weather in August
Temperature
The transition from July to August brings an average high-temperature of a still moderately hot 82.4°F (28°C), barely different from July's 83.8°F (28.8°C). August nights indicate a noticeable temperature drop from the daytime highs, with an average reading lowering to a refreshing 60.1°F (15.6°C).Heat index
In August, the heat index is estimated at a tropical 89.6°F (32°C). Continued exposure and engagement in activity might trigger tiredness and subsequently heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. 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 particularly relevant to children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
