May weather forecast
Santa Fe, FL

The last month of the spring, May, is a hot month in Santa Fe, Florida, with an average temperature ranging between max 86.2°F (30.1°C) and min 66.7°F (19.3°C).

Temperature

The beginning of May marks a minor shift in the average high-temperature, moving from April's moderately hot 80.6°F (27°C) to a tropical 86.2°F (30.1°C). During May, Santa Fe's temperature falls to a steady low-temperature average of 66.7°F (19.3°C).

Heat index

For May, the heat index is calculated to be a very hot 96.8°F (36°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
The metrics for the heat index are tailored for both shady environments and light winds. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Humidity

The average relative humidity in May is 72%.

Embrace precautions and observe sun safety norms. Evasion of sunburn is a necessity. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. Counter UV radiation's ill effects with clothing designed for sun safety and UV-resistant eyewear.
