Weather in May
Temperature
The shift into May is marked by a modest rise in the average high-temperature, moving from April's moderately hot 75.2°F (24°C) to a still warm 81.1°F (27.3°C). Nighttime temperatures record an average of 74.3°F (23.5°C) throughout May.Heat index
During May, the heat index is calculated to be a hot 86°F (30°C). Continuous activity in exposure could lead to a feeling of fatigue and heat cramps.In terms of the heat index, values are set with light wind and shade conditions in mind. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', determines the feeling of heat when you account for the relative humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.

A UV Index value of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV rays for the ordinary person.Note: In May, a daily maximum UV index of 7 leads to the following instructions:
Ward off overexposure. Defence against solar harm is crucial. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat. Be on guard! The reflective nature of sand and water boosts UV exposure.
