Weather in August
Temperature
With its high average temperature of 88°F (31.1°C) and a low of 82°F (27.8°C), August is regarded as the warmest month.Heat index
In August, the heat index is estimated at a fiery hot 100.4°F (38°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Metrics for the heat index primarily focus on shaded spots and light wind conditions. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'real feel' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
Humidity
The average relative humidity in August is 71%.Rainfall
The month with the most rainfall is August, when the rain falls for 20.3 days and typically aggregates up to 2.2" (56mm) of precipitation.Ocean temperature
With an average ocean temperature of 86.5°F (30.3°C), August is the month with the warmest seawater.Note: When the aim is to cool down, temperatures above 86°F (30°C) in waters might not be very inviting.

Sunshine
The average sunshine in August is 10.7h.UV index
The months with the highest UV index are May through September, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for the average person.Note: In August, the average maximum UV index of 7 translates into the following recommendations:
Continue precautions and advocate sun safety advice. Deterrence of sunburn is indispensable. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Select sunglasses that boast both UVA and UVB protection to limit the adverse effects of the sun on the eyes. Heads up! The reflection of sand and water notably intensifies UV rays from the Sun.
