Temperature

Gampola's May showcases an average high-temperature of a still hot 30.1°C (86.2°F), hardly distinct from April's 31.2°C (88.2°F). May's average low-temperature reading settles at a pleasant 21.8°C (71.2°F).

Heat index

In May, the heat index is calculated to be a torrid 38°C (100.4°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.
Consider that heat index readings are for situations in the shade and light wind. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. 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 babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When there is abundant moisture in the air, the body's cooling through the evaporation process becomes less effective, leading to the sensation of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

The average relative humidity in May is 80%.
