I have highlighted the rain season on the east and west coast. So, when you travel to the island next time, you can find the places where you can stay dry.
Monsoon decides the Sri Lanka rain season
Sri Lanka weather can be categorized as warm tropical, which is under the influence of Monsoon on the Indian subcontinent. Seasonal monsoon wind is the main contributor to the island’s rainfall that has six months changing the pattern, Summer monsoon (from April to November) and winter monsoon (November to April). The central part of the island, which is mainly comprised of mountains, shows a totally different climate than the rest of the country. According to the Sri Lanka weather pattern, summer monsoon or North-East monsoon brings the rain from April to November and soaks the North, East, Southern and some parts of the Island’s central region.
More than half of the island’s land area is covered by the North-East monsoon and the area is categorized under the dry zone. Estimated yearly rainfall in the dry zone areas of the island including Jaffna peninsula is 1500 to 2500 mm. The months of November, December and January considered being the main raining period of the year for the dry zone. Yala and the surrounding of Katagarama are categorized under the arid zone with the minimum yearly rainfall in the island. As the name suggests the area is dry for most of the year and the yearly rainfall estimated to be less than 1500 mm. The temperature of the dry zone is very high compared to the rest of the island and unlike other climate zones, most of the green cover is comprised of throne bushes.
West, South and South-West parts of the island are recording the highest rainfall in the island, which is between 2500 to 5000 mm. Wet zone of the island mainly comprised of low land of western Sri Lanka and the western side of the central mountain range. Winter monsoon is the main contributor of yearly rainfall of wet zone. The monsoon wind enters the island from South-West part of the island and soaks the Western parts of the central mountains; the leeward side of the mountain range remains dry owing to the dry wind that resulted from the rain in the western part of the mountain range. The wind which passes in the direction of the Eastern slope of the mountain range is called “Kachchan wind”, which is very dry as it dropped all of its water on the western slope of the mountain, and that increases the oppressive heat of the North and Eastern parts of Sri Lanka.
The unique pattern of the monsoon wind which changes in every six months makes Sri Lanka an ideal holiday destination at any time of the year in the region. Some parts of the island stay dry and show the best climate for holiday at any given time of the year. When the North-East monsoon soaks the North and Eastern Sri Lanka west coast experience the dry weather while the South and Western Sri Lanka experience the rainy season from April to November, North and Eastern parts of the island experience the dry climate.
Sri Lanka weather November
Generally, Sri Lanka weather in November is dry and humid. This is the month, in which monsoon migrate from west coast of Sri Lank to the east coast. As it moves to the east coast from the west so is the rain, usually, the monsoon wind accompanies the heavy rain, gusty wind and lightning. During this transition, Sri Lanka weather in November is relatively dry throughout the island. When the monsoon settled over the eastern part of the country over the next few weeks the entire east coast experience the heavy rain. But the dry weather settles over the west and southern part of the island and remains dry until the next change of monsoon wind in the month of May.
The temperature of Sri Lanka
Being an island close to the equator, the temperature of Sri Lanka measured to be between 29 to 35 ˚C in the lower elevations (coastal areas), however, the temperature in the dry zone of Sri Lanka can o up to around 40 ˚C in the draught season. The humidity of the lower elevation measured to be around 85% making it adding some discomfort for the existing high temperature. Constant wind of the beaches makes it more comfortable to live in the coastal belt than the cities that are away from the coast. At the higher elevations of the island, is the more comfortable climate with low temperatures around 25˚C. Nuwara Eliya lies 2000 meters above sea level and records the lowest temperature in the island. The temperature of Nuwara Eliya can fall up to -2 ˚C after the sunset in the months of November and December. The highest temperature of the island recorded in the North and Eastern parts of the island between 35 to 37 ˚C average temperatures.
