May weather forecast
Divulapitiya, Sri Lanka

May continues the pattern set by April, maintaining the warm temperature but with an increased level of humidity. The rising humidity brings with it an increase in rainfall, with a significant rise to 204mm (8.03"). Despite this, the length of daylight hours remains constant and the cloud coverage does not see a dramatic increase. Mirroring the typical tropical weather, the constant mix of sun and rain works in tandem to further enrich the environment. The winds continue to pick up speed, adding an additional layer to the city's climate conditions.

Temperature

With the onset of May, the average high-temperature registers at a still hot 30.8°C (87.4°F), subtly different from April's 32°C (89.6°F). May nighttime temperatures hover close to the daytime peak with an average of 26.4°C (79.5°F).

Heat index

For May, the heat index is calculated to be an extremely hot 40°C (104°F). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
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. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
