Weather in August
Temperature
Entering August, Round O's average high-temperature reads a still tropical 90.5°F (32.5°C), indicating a close resemblance to the previous month's climate. Throughout the nights in August, an average low-temperature of 73.2°F (22.9°C) is noted.Heat index
The heat index for August is computed to be a life-threatening hot 113°F (45°C). Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. 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. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. 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. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
Humidity
August and December, with an average relative humidity of 77%, are the most humid months.Rainfall
The month with the most rainfall is August, when the rain falls for 20.2 days and typically aggregates up to 3.15" (80mm) of precipitation.Snowfall
March through December are months without snowfall.Daylight
The average length of the day in August is 13h and 20min.On the first day of the month, sunrise is at 6:36 am and sunset at 8:20 pm. On the last day of August, sunrise is at 6:56 am and sunset at 7:47 pm EDT.
Sunshine
In Round O, the average sunshine in August is 10.4h.UV index
June through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for the ordinary person.Note: The maximum daily UV index of 7 in August converts into the following recommendations:
Shield from overexposure. Defense against sun-related harm is required. 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. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
