January weather forecast
Divulapitiya, Sri Lanka

Divulapitiya's January weather sees the year off to a warm start, keeping residents and visitors comfortable with the moderate temperatures typical of Sri Lankan climate. Slightly cooler evenings provide relief from the warm daytime temperatures. A shift in weather conditions can be detected with humidity, rainfall, and wind speed on the rise, reaching a monthly average of 73% humidity, 29mm (1.14") rainfall, and wind blowing at 16.2km/h (10.1mph). A fair balance of sunny and cloudy days is observed, adding variety to the weather patterns. Despite the occasional rain, outdoor activities can still be enjoyed as the rainfall is generally light and short-lived.

Temperature

The arrival of January sees an average high-temperature of a tropical 30.8°C (87.4°F), hardly diverging from December's 29.9°C (85.8°F). Divulapitiya's temperature lowers to a mean of 22.8°C (73°F) during the nights in January.

Heat index

For January, the heat index is calculated to be a very hot 38°C (100.4°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
The heat index's values are generally associated with conditions in shade and light breezes. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. 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. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Humidity

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

Rainfall

January is the month with the least rainfall. Rain falls for 9.7 days and accumulates 29mm (1.14") of precipitation.

Sunshine

January through April, with an average of 9.2h of sunshine, are months with the most sunshine.

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 threat to health from exposure to the Sun's UV rays for the ordinary person.
Note: In January, the maximum UV index of 7 transforms into these recommendations:
Guard against overexposure. Protection from sun-induced harm is essential. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses.
