May weather forecast
Galedanda, Sri Lanka

May, the last month of the spring in Galedanda, is another tropical month, with an average temperature ranging between min 26.3°C (79.3°F) and max 30.6°C (87.1°F).

Temperature

The transition from April to May sees an average high-temperature of a still hot 30.6°C (87.1°F), indicating a minor variance from the prior month. During May, the nighttime temperatures align closely with the daytime averages, measuring a moderately hot 26.3°C (79.3°F).

Heat index

The heat index for May is appraised at a scorching 40°C (104°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Young ones often do not realize the necessity to rest and replenish their fluids. Thirst is a delayed indication of dehydration - keeping hydrated, particularly in prolonged physical activity, is crucial.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Note: In May, the maximum UV index of 6 translates into these guidelines:
Guard against overexposure. Protection from sun-induced harm is essential. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
