Weather in May
Temperature
May's onset brings a minor rise in the average high-temperature, moving from an agreeable 72.7°F (22.6°C) in April to a warm 80.8°F (27.1°C). Gillham records an average nighttime low of 61°F (16.1°C) in May.Heat index
In May, the heat index is computed to be a tropical 86°F (30°C). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.

Prevent overexposure. Protection from the sun's harmful effects is needed. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Combat UV radiation's detrimental effects with sun-safe clothing and UV-blocking eyewear.
