November weather forecast
Sigiriya, Sri Lanka

November brings a slight decline in the temperature range to 30.5°C (86.9°F). Even if there is a drop in the rainfall to 166mm (6.54"), the number of rainy days increase. This month offers fewer daylight hours, which combined with the cloudy weather, keeps the sunshine duration to the minimum. The atmospheric pressure shows a slight upward trend compared to October. Therefore, a good rain jacket and waterproof shoes would be prudent if planning to visit in this month.

Temperature

November registers an average high-temperature of a still tropical 30.5°C (86.9°F), slightly varied from October's 32.7°C (90.9°F). In November, Sigiriya reports a consistent average low-temperature of 22°C (71.6°F) during the nights.

Heat index

November's mean heat index is computed to be a blistering 40°C (104°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
Evaporating sweat is a key way the human body dispels excessive warmth, all thanks to the process of perspiration. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

The average relative humidity in November is 82%.

UV index

January, November and December, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index value of 6 to 7 symbolizes a high health hazard from exposure to the Sun's UV radiation for average individuals.
Note: The maximum UV index of 6 during November translates into these guidelines:
Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
