Weather in May

May, the last month of the spring in Cuba, is another very hot month, with an average temperature ranging between min 24.7°C (76.5°F) and max 35.5°C (95.9°F).

Temperature

The onset of May notes an average high-temperature of a still fiery hot 35.5°C (95.9°F), subtly shifted from April's 37.4°C (99.3°F). In May, Cuba's temperature tends to fall to an average low of 24.7°C (76.5°F) during the night.

Heat index

May's mean heat index is computed to be a life-threatening hot 53°C (127.4°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.
Heat index data is primarily for areas with shade and subjected to light winds. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values remain especially vital for babies and toddlers. 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.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Humidity

The average relative humidity in May is 72%.

Rainfall

In Cuba, during May, the rain falls for 18.3 days and regularly aggregates up to 86mm (3.39") of precipitation. Throughout the year, there are 134.6 rainfall days, and 461mm (18.15") of precipitation is accumulated.

Daylight

In Cuba, the average length of the day in May is 12h and 38min.
On the first day of the month, sunrise is at 05:40 and sunset at 18:12. On the last day of May, sunrise is at 05:35 and sunset at 18:19 -05.

Sunshine

The average sunshine in May is 10.6h.

UV index

The months with the lowest UV index are January, April through December, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high health risk from unprotected exposure to Sun's UV rays for the ordinary person.
Note: A maximum high daily UV index of 7 during May translates into the following directions:
Guard oneself from overexposure. Defence against sun injury is vital. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
