August weather forecast
Lake Buena Vista, FL

Entering August, Lake Buena Vista continues to experience the peaks of the Florida summer. It persistently records high temperatures, equal to July’s peak value of 91°F (32.8°C). Concurrently the humidity levels remain elevated, forming a mixture of heat and mist that defines a typical Floridian August. A significant feature of August's weather is the frequency and intensity of thunderstorms, casting dramatic displays against the Florida skyline. Although August's weather is intense, it is seen as the hallmark of the region's summer dictum, maintaining Lake Buena Vista's summertime charm.

Temperature

The warmest month is August, with an average high-temperature of 91°F (32.8°C) and an average low-temperature of 76.8°F (24.9°C).

Heat index

August's average heat index is computed to be a blazing hot 113°F (45°C). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.
Heat index determinations are made taking into account the shade and light air movements. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Juveniles often do not understand the need to recuperate and rehydrate. Thirst is a delayed symptom of dehydration - hence, it is vital to maintain hydration, particularly during ongoing physical activities.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
