October is a transitional period in all parts of the island, a month of change as the south-west monsoon comes to an end, usually in the second half of the month. Normally, Rainfall remains high on the south-western lowlands in the first half of October, with temperatures well below their annual peak. Swimming in the sea at the south-western coast is often not recommended in October. Some hotels will have their red flags out to warn that sea bathing can be dangerous.
Precipitation will also be high in the Tea Country. All in all, October is one of the wettest months of the year country-wide. Across the country first cyclones can occur, bringing with them heavy rain.
The driest period in the northern and eastern lowland comes to an end, too. In the Cultural Triangle and in the wilderness area in and around Yala National Park. In October the sky in the dryzone will not be perfectly blue any more in October, rainfall is likely to become a regular feature towards the end of the month with the arrival of the north-eastern monsoon, also called “anti-monsoon”. First rainfalls occur even earlier, and nature will recover. Advantage for travellers is, roads will be less dusty and the scenery will be less greyish and brown but ingreasingly green. The heaviest precipitation and storms usually take place in November.
However, predictions of seasonal weather conditions in Sri Lanka have become increasingly difficult maybe due to climate change during the last decade. Actually, there are periods of blue sky as well as rainy days in almost every month in all climate zones of the island. Even heavy floods can occur during local dry seasons. October in particular is a hard month to call when it comes to judging the best beach conditions.
The begin of northern-hemisphere autumn also is the beginning of bird migration, mainly to tropical areas such as Sri Lanka. This is why best time to visit bird sanctuaries such as Anawilundawa is during the months from October to April when more numerous species of birds can be spotted than during northern hemisphere summertime.
In Colombo and in the south-western lowlands, evening and nighttime thunderstorms are expected this week, particularly from Tuesday to Friday. The weekend will be more sunny again. In the Cultural Triangle, weather conditions will be fair.
