May weather forecast
Kossinna, Sri Lanka

May, the last month of the spring in Kossinna, is another tropical month, with temperature in the range of an average high of 30.1°C (86.2°F) and an average low of 21.8°C (71.2°F).

Temperature

At the onset of May, Kossinna records an average high-temperature of a still tropical 30.1°C (86.2°F), showing little deviation from the preceding month. Throughout May, Kossinna anticipates an average low-temperature of 21.8°C (71.2°F).

Heat index

Throughout May, the heat index is calculated to be a sweltering 38°C (100.4°F). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. 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 'feels like' or 'apparent temperature', is a measure of how hot it feels when the actual air humidity is factored in. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Humidity

In Kossinna, the average relative humidity in May is 80%.

Rainfall

In Kossinna, in May, it is raining for 28.6 days, with typically 163mm (6.42") of accumulated precipitation. Throughout the year, there are 278.4 rainfall days, and 1466mm (57.72") of precipitation is accumulated.

UV index

The months with the highest UV index are January through September, November and December, with an average maximum UV index of 6. A UV Index value of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for the average person.
Note: The daily high UV index of 6 during May translates into the following recommendations:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Using UVA and UVB-protective sunglasses and sun-protective clothing is effective against UV radiation.
