Weather in May
Temperature
The arrival of May brings a soft temperature shift, with the average high-temperature nudging from a moderately hot 78.6°F (25.9°C) in April to a still warm 84.9°F (29.4°C). During May, the temperature tends to dip to an average of 65.1°F (18.4°C) at night.Heat index
The heat index for May is calculated to be a tropical 93.2°F (34°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Understanding the heat index involves considering values for shaded locales with light wind. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.

A UV Index value of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV rays for ordinary individuals.Note: The daily high UV index of 7 during May translates into the following recommendations:
Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
