May weather forecast
Johnsons Corner, FL

Temperature

The arrival of May sees a recorded average high-temperature of a tropical 86.2°F (30.1°C), showing little divergence from the previous month's conditions. Johnsons Corner's average low-temperature is measured at a pleasant 68°F (20°C) during May.

Heat index

Throughout May, the heat index is computed to be a very hot 96.8°F (36°C). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.
Be advised, the heat index considers values for conditions in shade and with a light breeze. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
