The last month of the spring, May, is another tropical month in Pussella, Sri Lanka, with temperature in the range of an average low of 23°C (73.4°F) and an average high of 31.8°C (89.2°F).

Temperature

The transition into May shows a subtle variation to a still tropical 31.8°C (89.2°F) from April's 32.9°C (91.2°F) in the average high-temperature. Pussella, in the month of May, anticipates a consistent average low-temperature of 23°C (73.4°F).

Heat index

May's average heat index is estimated at a blistering 42°C (107.6°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

In May, the average relative humidity is 77%.
