The last month of the spring, May, is a hot month in Harvard, Florida, with an average temperature ranging between min 66.7°F (19.3°C) and max 86°F (30°C).

Temperature

In May, the meteorological conditions subtly change with the average high-temperature edging from a moderately hot 80.4°F (26.9°C) in April to a tropical 86°F (30°C). In Harvard, the expected average low-temperature for May is an enjoyable 66.7°F (19.3°C).

Heat index

During May, the heat index is appraised at a sweltering 96.8°F (36°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', evaluates the perceived heat by adding the effect of moisture in the air. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Humidity

In May, the average relative humidity is 72%.

Note: In May, a regular UV index of 7 translates into these guidelines:
Adopt measures and apply sun safety strategies. Shielding from skin and eye damage is necessary. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. A hat with a broad brim is indispensable, filtering out up to half of UV rays.
