Weather in August
Temperature
The arrival of August brings an average high-temperature of a still tropical 87.8°F (31°C), subtly diverging from July's 89.1°F (31.7°C). The nighttime temperature during August displays a significant divergence from daily peaks, averaging at a refreshing 59.2°F (15.1°C).Heat index
The heat index in August is computed to be a hot 89.6°F (32°C). With ongoing exposure and activity, one might experience weariness, and heat cramps could ensue.Consider that heat index readings are for situations in the shade and light wind. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
