November weather forecast
Polonnaruwa, Sri Lanka

The weather in November mirrors that of October, though with a slight decrease in rainfall and a minor drop in temperature. Despite these mild changes, the heavy rainfall continues to dominate Polonnaruwa's climate. Consistent weather patterns from October to November create a predictability that extends into early December.

Temperature

With the advent of November, Polonnaruwa's high-temperatures adjust to a still tropical 30.5°C (86.9°F), closely aligning with the preceding month. During the month of November, an average low-temperature of 22°C (71.6°F) is recorded.

Heat index

In November, the heat index is evaluated at a blisteringly hot 40°C (104°F). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. 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 'real feel', offers an insight into how hot it feels when we factor in moisture content. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Humidity

The average relative humidity in November is 82%.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. During bright days, sunglasses that offer UVA and UVB defense are recommended.
