August weather forecast
Orlando, FL

In August, the weather barely changes compared to July, temperatures oscillating between 76.8°F (24.9°C) to 91°F (32.8°C). It is the time when the heat, humidity, and precipitation all challenge the thresholds. However, the city does witness a slight decrease in daylight hours to 13.1, indicating the elongating shadows of an approaching autumn. Frequent showers continue, accompanied by the highest average relative humidity of the year at 77%. Wind speed sees a marginal increase, providing periods of cooler relief from the persistent heat.

Temperature

August is the month that records the highest temperatures, with averages ranging from a high of 91°F (32.8°C) to a low of 76.8°F (24.9°C).

Heat index

In August, the heat index is estimated at a life-threatening hot 114.8°F (46°C). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.
Understanding the heat index involves considering values for shaded locales with light wind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

Humidity

The months with the highest humidity are August and September, with an average relative humidity of 77%.

Rainfall

August is the month with the most rainfall. Rain falls for 24.6 days and accumulates 5.31" (135mm) of precipitation.

Sunshine

In Orlando, the average sunshine in August is 10.3h.

UV index

The months with the highest UV index are May through September, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for the ordinary person.
Note: The maximum UV index of 7 during August leads to these instructions:
Resist extreme sun exposure. Guarding against solar damage is essential. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
