January weather forecast
Madupitiya, Sri Lanka

January is a hot winter month in Madupitiya, Sri Lanka, with an average temperature ranging between min 23.4°C (74.1°F) and max 30.3°C (86.5°F).

Temperature

The dawn of January sees an average high-temperature of a tropical 30.3°C (86.5°F), subtly contrasting with December's 29.7°C (85.5°F). During the month of January, an average temperature of 23.4°C (74.1°F) is noted during the nights.

Heat index

The average heat index in January is evaluated at a torrid 37°C (98.6°F). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.
Research indicates the heat index considers values in shaded locales and with light winds. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', quantifies the warmth felt when relative humidity is considered. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

UV index

January through April, July, September through December, with an average maximum UV index of 7, are months with the highest UV index in Madupitiya. A UV Index estimate of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for average individuals.
Note: In January, a regular UV index of 7 translates into these guidelines:
Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
