Weather in May
Temperature
May comes with a subtle rise, with the average high-temperature adjusting from 77.4°F (25.2°C) in April to a still warm 85.3°F (29.6°C). Throughout May, an average low-temperature of 63.9°F (17.7°C) is expected.Heat index
In May, the average heat index is estimated at a torrid 95°F (35°C). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', reflects the blend of air temperature and relative humidity to give a temperature impression. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The process of perspiration is vital for the human body to get rid of excess warmth by allowing sweat to evaporate. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Take precautions against overexposure. Protection against sun damage is needed. 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. To cut down UV radiation exposure by about half, sport a wide-brim hat.
