February weather forecast
Welikada, Sri Lanka

The last month of the winter, February, is also a hot month in Welikada, Sri Lanka, with an average temperature varying between 31.7°C (89.1°F) and 23.1°C (73.6°F).

Temperature

The advent of February reveals an average high-temperature of a still tropical 31.7°C (89.1°F), showing minimal difference from the prior month. Welikada's nighttime temperature in February falls to an average of 23.1°C (73.6°F).

Heat index

For most parts of February, the heat index is calculated to be a scorching 41°C (105.8°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. An individual's perception of weather can be affected by a variety of elements including metabolic differences, being pregnant, and their level of physical exertion. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Humidity

The months with the lowest humidity are January and February, with an average relative humidity of 73%.

Rainfall

UV index

January through April, July, September, November and December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for average individuals.
Note: In February, the average maximum UV index of 7 translates into the following recommendations:
Resist extreme sun exposure. Guarding against solar damage is essential. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
