February weather forecast
Rakwana, Sri Lanka

The last month of the winter, February, is a hot month in Rakwana, Sri Lanka, with temperature in the range of an average high of 30.7°C (87.3°F) and an average low of 18.7°C (65.7°F).

Temperature

February's arrival shows an average high-temperature of a hot 30.7°C (87.3°F), hardly different from the previous month. Rakwana, after hot February days, encounters a marked drop to an average nighttime temperature of 18.7°C (65.7°F).

Heat index

Throughout February, the heat index is computed to be a blisteringly hot 40°C (104°F). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.
Remember that heat index calculations are made for conditions in the shade with light wind. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Humidity

January and February, with an average relative humidity of 80%, are the least humid months.

Rainfall

In February, the rain falls for 19.8 days. Throughout February, 109mm (4.29") of precipitation is accumulated. In Rakwana, during the entire year, the rain falls for 317.3 days and collects up to 2422mm (95.35") of precipitation.

Sunshine

In February, the average sunshine in Rakwana is 8.3h.

UV index

The months with the highest UV index are January through August, November and December, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for ordinary individuals.
Note: A maximum high UV index of 6 in February translates into the following recommendations:
Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. 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. During bright days, sunglasses that offer UVA and UVB defense are recommended.
