November weather forecast
Arugam Bay, Sri Lanka

November embodies the full-fledged monsoon season with the maximum rainfall of 220mm (8.66") witnessed in Arugam Bay throughout the year. Coupled with the increasing cloud percentages, which block out most of the sun, November provides an intriguing change of weather from a sun-soaked beach to a monsoon-drenched shoreline. The peak in humidity gives the air a noticeably denser feel. Venturing out during this month might require waterproof gear due to frequent showers. However, November also celebrates the unique, wet beauty of Arugam Bay, as it prepares to wrap up the year with the monsoon fervor.

November brings an average high-temperature of a warm 29.3°C (84.7°F) in Arugam Bay, showing a slight difference from October's 31°C (87.8°F). During November, the nighttime temperatures align closely with the daytime averages, measuring a still moderately hot 25°C (77°F).

Heat index

The average heat index in November is computed to be a very hot 35°C (95°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

The average relative humidity in November is 79%.

Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes. Take note! The UV strength of the Sun elevates when reflected off water and sand.
