Temperature

The average high-temperature during May is a moderately hot 29.5°C (85.1°F), almost matching the conditions of the preceding month. Dodanduwa's May nights demonstrate minimal variation from the daytime temperatures, with an average of 26.7°C (80.1°F).

Heat index

The heat index in May is evaluated at a very hot 36°C (96.8°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. 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 'felt air temperature' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Humidity

In May, the average relative humidity is 81%.

Note: The maximum UV index, 6 during May, leads to the following recommendations:
Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
