Weather in August
Temperature
The shift into August reveals an average high-temperature of a still warm 81.1°F (27.3°C), closely mirroring July's climate. The temperature during August experiences a small drop from daytime peaks, recording an average of 77.7°F (25.4°C) at night.Heat index
The heat index value during August is computed to be a tropical 86°F (30°C). If one persists in activity during exposure, it could induce weariness and subsequently, heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.

Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Stay sun-safe with clothing that is both closely woven and worn loosely. Be wary! Reflections from sand and water make UV radiation more intense.
