Weather in January
Temperature
January brings an average high-temperature of a still moderately hot 29.6°C (85.3°F), nearly identical to the preceding month. Throughout January, Eppawala experiences a low-temperature average of 20.5°C (68.9°F).Heat index
January's average heat index is evaluated at a fiery hot 37°C (98.6°F). More preventive actions are needed, risk of heat exhaustion and heat cramps is significant. Prolonged activity may trigger heatstroke.Understand that the heat index values take into account shaded locations and mild winds. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. 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 of high significance for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

A UV Index of 6 to 7 symbolizes a high health risk from unsafe exposure to UV radiation for the ordinary person.Note: In January, a daily maximum UV index of 6 leads to the following instructions:
Shun overexposure. Protection from sun ravages is indispensable. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
