Weather in May

May, the last month of the spring in Parakandeniya, is also a hot month, with an average temperature varying between 26.3°C (79.3°F) and 30.6°C (87.1°F).

Temperature

The advent of May sees the average high-temperature at a still hot 30.6°C (87.1°F), subtly shifted from April's 31.8°C (89.2°F). In Parakandeniya, the nighttime temperature in May descends gently to an average of 26.3°C (79.3°F).

Heat index

The heat index for May is evaluated at an extremely hot 40°C (104°F). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
