Weather in August
Temperature
The average temperatures reach their apex in August, averaging 88.9°F (31.6°C) at the high end and 79.7°F (26.5°C) at the low end.Heat index
August's mean heat index is evaluated at a blistering 105.8°F (41°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
Humidity
In Iona, the average relative humidity in August is 74%.Rainfall
August is the month with the most rainfall. Rain falls for 24 days and accumulates 3.94" (100mm) of precipitation.Ocean temperature
With an average ocean temperature of 86.7°F (30.4°C), August is the month with the warmest seawater.Note: Waters that are warmer than 86°F (30°C) might not provide the cooling effect most people seek during hot days.
Daylight
In August, the average length of the day is 13h and 3min.On the first day of August, sunrise is at 6:53 am and sunset at 8:14 pm. On the last day of the month, sunrise is at 7:07 am and sunset at 7:48 pm EDT.
Sunshine
In August, the average sunshine is 9.6h.UV index
May through September, 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 risk from unsafe exposure to UV radiation for average individuals.Note: The maximum UV index of 7 during August translates into these guidelines:
Continue precautions and advocate sun safety advice. Deterrence of sunburn is indispensable. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage. Heads up! Sand and water reflection magnifies the UV exposure from the Sun.
