August weather forecast
Sri Lanka

August in Sri Lanka represents a transition period where the southwest monsoon's influence wanes, giving way to clearer skies and drier conditions. Average temperatures during this month hover between 20°C (68°F) to 26°C (78.8°F). In contrast, the central highland regions, including Nuwara Eliya, maintain their cooler ambiance with readings from 10°C (50°F) to 22°C (71.6°F).

August's weather is noticeably drier than July, especially in the previously rain-soaked southwestern regions. As a result, the environment feels less humid, making outdoor activities more enjoyable. The reduction in rainfall presents a stark contrast to the heavy showers that dominated the months of June and July.

The eastern coast, particularly areas like Batticaloa, continues its trend of experiencing minimal rainfall, favoring sunnier days and warm temperatures. This region remains one of the most suitable for beach and sea activities during this month.

Moving into September, the climate remains relatively dry across most of the island. However, there's an underlying anticipation as Sri Lanka slowly approaches the onset of the northeast monsoon, which typically starts impacting the weather patterns towards the end of the year.
