Weather in January
Temperature
With the transition into January, Ingiriya notes an average high-temperature of a still warm 29.3°C (84.7°F), closely resembling December. Throughout January, the temperature falls to an average low of 18.8°C (65.8°F).Heat index
The heat index value for January is appraised at a very hot 36°C (96.8°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Heat index determinations are made taking into account the shade and light air movements. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. 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.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When the air contains significant moisture, the efficiency of the evaporation process decreases, preventing the body from cooling down effectively and creating a feeling of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
Humidity
January and February, with an average relative humidity of 80%, are the least humid months.Rainfall
The month with the least rainfall is January, when the rain falls for 18.9 days and typically collects 85mm (3.35") of precipitation.Daylight

Sunshine
The average sunshine in January is 8.3h.UV index
January through August, November and December, with an average maximum UV index of 6, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health hazard from unsafe exposure to UV radiation for the average person.Note: A maximum UV index of 6 in January translates into the following recommendations:
Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
