Weather in August

In August, the weather barely changes compared to July, temperatures oscillating between 76.8°F to 91°F. 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

In Orlando, Florida, August records the highest average temperatures, peaking at 91°F and reaching a low of 76.8°F.

Heat index

August's heat index is calculated to be a burning hot 114.8°F. Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.
Heat index values are typically calculated for conditions of shade and a light breeze. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. 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 especially vital to children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
