Temperature

Lake Buena Vista, Florida, marks the start of May with an average high-temperature of a hot 86.5°F (30.3°C), hinting at a slight fluctuation from April's 82.6°F (28.1°C). Throughout the May nights, Lake Buena Vista encounters a low-temperature of 68.9°F (20.5°C).

Heat index

May's heat index is evaluated at a torrid 96.8°F (36°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. 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 highly critical for babies and toddlers. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
