The climate throughout September in Sri Lanka is deteriorating throughout the country. Temperatures are rising again while rainfall is still intense. However, the weather in the Sri Lankan localities provide the opportunity to enjoy the sunshine and the cloud thinnings between showers.
Sptember in Colombo and the West Coast of the Island
It is hot in Colombo and its surroundings, especially in the middle of the day. Yet because of the rain that continues to fall at any time of day and night, the weather is barely favorable.
September in Jaffna and the Extreme North of the Island
The weather in Sri Lanka throughout September is more favorable in the north, as in the locality of Jaffna. The first weeks of September are pleasant and sunny. Towards the end of the month, the mornings are wetter.
September in Trincomalee and the Northeast of the Island
It is hot again in the northeast of the island of Ceylon, especially since the rains are relatively weak. Midday is particularly hot. Thanks to the sea breeze that tempers the heat, the atmosphere is still pleasant.
September in Nuwara Eliya and the Central Plain
The warmth is comfortable in Nuwara Eliya and its surroundings, yet with 26 days of intermittent showers in the day and intense rain in the evening, the September weather in Sri Lanka in the central plain, is just acceptable.
