Weather in May

Venturing into May, Beruwala records the highest rainfall of the year at 303mm (11.93"), making it distinct from the other months. The significantly enhanced precipitation, coupled with the persistent high temperature, contributes to the considerable rise in humidity, making the air thicker and heavier.

However, June continues this pattern with even higher precipitation but a slight decrease in temperature.

May commences in Beruwala with an average high-temperature of a still tropical 30.2°C (86.4°F), showing little deviation from April's 31.3°C (88.3°F). Beruwala's May nights observe a minor shift from the daytime temperatures, resulting in an average dip to a warm 26.3°C (79.3°F).

Heat index

The heat index for May is appraised at a torrid 39°C (102.2°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Heat index determinations are made taking into account the shade and light air movements. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
