August in Sri Lanka is a month when the weather is attractive over much of the island, just in time for the European summer holidays!
Sri Lanka's entire south and west coast region usually experiences a considerable fall in rainfall compared to July and September (both of which can also provide decent amounts of good weather). Water sports are back in full swing and temperatures average out around 29C.
It's also a good month to visit the capital, Colombo. Consider heading north of Colombo to places such as Negombo and Kalpitiya for some of the best west-coast weather.
The gorgeous east coast beaches remain in high season and are often the first target of travellers whose priority is sunshine then more sunshine.
Further north in the Cultural Triangle temperatures remain high at around 32C, rainfall is at a minimum and the dry breezes of the previous two months have subsided.
