Weather in May

May, the last month of the spring in Cocoa, is also a moderately hot month, with temperature in the range of an average high of 82.4°F (28°C) and an average low of 72°F (22.2°C).

Temperature

The average high-temperature is a still moderately hot 82.4°F (28°C) in May, hardly different from the 79°F (26.1°C) recorded in April. Cocoa sees an average low-temperature of 72°F (22.2°C) during May.

Heat index

For most parts of May, the heat index is calculated to be a hot 87.8°F (31°C). Exhaustion might be the outcome of enduring exposure and continuous activity, with a risk of heat cramps.
It is emphasized that the heat index's values are meant for shaded zones with mild winds. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.

Note: An average maximum UV index of 7 in May leads to these recommendations:
Shun overexposure. Protection from sun ravages is indispensable. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized. Heed this! UV intensity is much stronger when reflected off sand and water.
