Sri Lanka is a year-round destination with a tropical monsoon climate. The location near the equator, mountains in the interior of the island and monsoons, influenced by the seasonal changes of the main wind directions, determine the climate:
Between mid-May and the end of September, the rainy southwest monsoon "Yala" brings heavy rainfall on the west and southwest coasts. The east and northeast, including Nilaveli, remain dry during these times.
From October to mid-April, the less pronounced northeast monsoon "Maha" concentrates precipitation in the north and east of the island, incl. in Nilaveli. While it may rain during the monsoon season, there are also sunny phases. Nature is now in lush greenery, the sea is more agitated, temperatures are less high.
Between the monsoons it is rather wet and cloudy with short showers. Temperatures in Sri Lanka are high and vary only little throughout the year. The highest temperatures occur from March to June. From November to January is the coolest time. The values are on average 26 - 31 °C. At night, temperatures seldom drop below 25 °C. The humidity is quite high at
70 - 90%.
The warm and humid climate is particularly suitable for Ayurvedic cures, because the vessels expand and the pores open. Thereby the herbal oils penetrate particularly well and deeply into the body. In order to maintain heat in the body, there are no air conditioning units in either the treatment rooms or the accommodations.
