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 November's advent, Polonnaruwa, Sri Lanka, sees an average high-temperature of a still hot 30.5°C (86.9°F), subtly shifted from October's 32.7°C (90.9°F). Throughout the month of November, Polonnaruwa expects an average low of 22°C (71.6°F).

Heat index

For most parts of November, the heat index is computed to be a blistering 40°C (104°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
Note that heat index values are valued for light wind and location in the shade. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Humidity

In November, the average relative humidity is 82%.

Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
