Weather in January
Temperature
The arrival of January brings an average high-temperature of a still warm 29.2°C (84.6°F), closely following the temperature pattern of December. During January, Egodaduwa observes a consistent average nighttime temperature of 24°C (75.2°F).Heat index
January's heat index is computed to be a sweltering 35°C (95°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.

A UV Index of 6 to 7 symbolizes a high health hazard from unprotected exposure to Sun's UV rays for ordinary individuals.Note: The maximum UV index, 7 during January, leads to the following recommendations:
Ward off overexposure. Defence against solar harm is crucial. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears.
