May weather forecast
Alakoladeniya, Sri Lanka

May, the last month of the spring in Alakoladeniya, is another tropical month, with an average temperature fluctuating between 30.1°C (86.2°F) and 21.8°C (71.2°F).

Temperature

The initiation of May records an average high-temperature of a still tropical 30.1°C (86.2°F), displaying a near consistency with the previous month. In May, the average low-temperature records at a pleasant 21.8°C (71.2°F) during the nights.

Heat index

May's mean heat index is evaluated at a sweltering 38°C (100.4°F). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. 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.

Humidity

The average relative humidity in May is 80%.

Note: A typical high UV index of 6 in May suggests the following recommendations:
Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. Equip yourself with UVA and UVB-filtering sunglasses on clear, sunny days.
