The last month of the spring, May, is another tropical month in Polgolla, Sri Lanka, with an average temperature ranging between min 21.8°C (71.2°F) and max 30.1°C (86.2°F).

Temperature

Polgolla's weather in May indicates an average high-temperature of a still hot 30.1°C (86.2°F), nearly consistent with the 31.2°C (88.2°F) of April. Polgolla, during May nights, observes an average temperature of 21.8°C (71.2°F).

Heat index

The heat index value during May is estimated at a very hot 38°C (100.4°F). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.
In the scope of the heat index, its values resonate with shade and light wind conditions. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children often fail to recognize the requirement to rest and rehydrate. Thirst, being a late symptom of dehydration, underlines the importance of maintaining hydration, especially during ongoing physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Note: The maximum UV index of 6 during May translates into these guidelines:
Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
