Weather in May
Temperature
In May, Jean-Rabel's weather conditions record an average high-temperature of a still moderately hot 29.3°C (84.7°F), demonstrating little divergence from the preceding month. May witnesses an average nighttime temperature of 22.5°C (72.5°F).Heat index
The heat index value for May is calculated to be a torrid 35°C (95°F). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. 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. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

A UV Index reading of 6 to 7 represents a high threat to health from exposure to the Sun's UV rays for the average person.Note: The maximum UV index of 7 during May translates into these guidelines:
Deflect overexposure. Sun protection is a necessity. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
