Weather in August
Temperature
August, characterized by an average high temperature of 85.3°F (29.6°C) and a low temperature of 83.1°F (28.4°C), is generally the warmest month.Heat index
The heat index value during August is calculated to be a very hot 95°F (35°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', reflects the feeling of heat when considering both air temperature and humidity. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

April through October, with an average maximum UV index of 7, are months with the highest UV index in Cudjoe Key. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV radiation for the average person.Note: The UV index of 7 during August translates into the following guidance:
Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation. Note! Reflective surfaces like sand and water heighten the UV radiation levels.
