Weather in January
Temperature
Lunuwila's average high-temperature in January is a tropical 30.8°C (87.4°F), indicating a subtle variation from December. Lunuwila's nighttime temperature in January falls to an average of 22.8°C (73°F).Heat index
For January, the heat index is estimated at a fiery hot 38°C (100.4°F). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
Humidity
January and February, with an average relative humidity of 73%, are the least humid months.Rainfall
The month with the least rainfall is January, when the rain falls for 9.7 days and typically collects 29mm (1.14") of precipitation.Daylight

Sunshine

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 value of 6 to 7 symbolizes a high health vulnerability from unsafe exposure to UV radiation for ordinary individuals.Note: In January, the maximum UV index of 7 suggests this advice:
Resist extreme sun exposure. Guarding against solar damage is essential. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
