The last month of the spring, May, is also a moderately hot month in Rattlesnake, Florida, with an average temperature ranging between min 71.4°F (21.9°C) and max 85.8°F (29.9°C).

Temperature

The advent of May sees the average high-temperature at a still moderately hot 85.8°F (29.9°C), subtly shifted from April's 81.7°F (27.6°C). Throughout the month of May, Rattlesnake observes an average nighttime temperature of 71.4°F (21.9°C).

Heat index

The heat index value for May is evaluated at a torrid 95°F (35°C). Implement additional preventive actions, heat cramps and heat exhaustion are potential hazards. Heatstroke could follow prolonged activity.
Remember that heat index calculations are made for conditions in the shade with light wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. 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. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Note: An average maximum UV index of 7 in May leads to these recommendations:
Inhibit overexposure. Warding off sun damage is of utmost importance. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
