August, although marked by less soaring temperatures as compared to July, continues to inherit the intense summer heat. The month's rainfall amounts to 2.28" (58mm), making it less rainy than its predecessor, July, yet more rainfall prone than the ensuing September. Contrasting with the rainfall, the amount of sunlight is relatively high, adding to the overall warmth. The sea attains its yearly hottest at a temperature of 82.7°F (28.2°C), rendering water sports remarkably enjoyable.

Heat index

The average heat index in August is estimated at a sweltering 96.8°F (36°C). Adopt extra safety steps, risk of heat exhaustion and heat cramps is notable. Sustained activity might cause heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
