Weather in May
Temperature
As May begins, there's a slight increase in the average high-temperature, moving from 78.8°F (26°C) in April to a still warm 85.6°F (29.8°C). Havana's May nights cool down to an average low-temperature of 64.9°F (18.3°C).Heat index
May's average heat index is estimated at a fiery hot 95°F (35°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
