May weather forecast
Ambalangoda, Sri Lanka

May, the last month of the spring in Ambalangoda, is another warm month, with an average temperature varying between 29.5°C (85.1°F) and 26.7°C (80.1°F).

Temperature

The shift to May signals an average high-temperature of a warm 29.5°C (85.1°F), subtly varied from April's 30.3°C (86.5°F). Ambalangoda's nighttime average temperature in May subtly descends to 26.7°C (80.1°F) from the daily highs.

Heat index

The heat index value during May is evaluated at a very hot 36°C (96.8°F). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.
Understanding the heat index involves considering values for shaded locales with light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.

Humidity

The average relative humidity in May is 81%.

UV index

May and September, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index value of 6 to 7 symbolizes a high threat to health from unprotected exposure to Sun's UV rays for the ordinary person.
Note: The maximum daily UV index of 6 during May translates into the following directions:
Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage 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. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage. Beware! Reflections from sand and water can intensify the Sun's UV radiation.
