Weather in May
Temperature
The advent of May denotes an average high-temperature of a still hot 30.4°C (86.7°F), subtly different from April's 31.8°C (89.2°F). Throughout May, Nahuizalco records an average temperature of 23.3°C (73.9°F) at night.Heat index
The average heat index in May is appraised at a sweltering 38°C (100.4°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance 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.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

A UV Index estimate of 6 to 7 represents a high health hazard from unprotected exposure to Sun's UV rays for the average person.Note: In May, a regular UV index of 7 translates into these guidelines:
Prevent overexposure. Protection from the sun's harmful effects is needed. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
