Weather in May
Temperature
Sishui's weather in May shows a rise in the average high-temperature, moving up from April's pleasant 20.9°C (69.6°F) to a warm 27.3°C (81.1°F). An average low-temperature of 15.5°C (59.9°F) marks the nights throughout May.Heat index
During May, the heat index is computed to be 28°C (82.4°F). A sense of exhaustion might occur with extended exposure and activity, potentially causing heat cramps.It is essential to grasp that the heat index's numbers are for shade and light wind settings. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. 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.
