November weather forecast
Ragama, Sri Lanka

The last month of the autumn, November, is another hot month in Ragama, Sri Lanka, with an average temperature varying between 24.5°C (76.1°F) and 30.1°C (86.2°F).

Temperature

With the start of November, Ragama measures an average high-temperature of a still hot 30.1°C (86.2°F), not significantly differing from October's 30°C (86°F). During November, an average low-temperature of 24.5°C (76.1°F) is observed.

Heat index

During November, the heat index is calculated to be a very hot 38°C (100.4°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
In the scope of the heat index, its values resonate with shade and light wind conditions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Humidity

In November, the average relative humidity is 79%.

Rainfall

In November, the rain falls for 25.7 days. Throughout November, 191mm (7.52") of precipitation is accumulated. In Ragama, during the entire year, the rain falls for 289.4 days and collects up to 2262mm (89.06") of precipitation.

UV index

The months with the highest UV index are January through April, July, September, November and December, with an average maximum UV index of 7. A UV Index reading of 6 to 7 represents a high health risk from exposure to the Sun's UV rays for average individuals.
Note: In November, the maximum UV index of 7 suggests this advice:
Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
