April weather forecast
Kosgoda, Sri Lanka

April, like March, is a hot spring month in Kosgoda, Sri Lanka, with an average temperature fluctuating between 21.1°C (70°F) and 30°C (86°F).

Temperature

April's climate shows a minor adjustment in average high-temperatures to a still hot 30°C (86°F) from March's 31.1°C (88°F). Kosgoda, during the nights of April, experiences an average temperature drop to an agreeable 21.1°C (70°F).

Heat index

During April, the heat index is computed to be a sweltering 39°C (102.2°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Employ safeguards and advocate sun safety protocols. Shielding against skin and eye damage is crucial. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
