The weather in Sri Lanka is unpredictable. It can change from heavy rain to beautiful sunshine within one hour. At Tangalle, and I guess in other parts of the country -- except maybe for the mountains -- the rain doesn't last a long time. A few minutes up to one hour; the sun is quickl back. And it is always warm. We see the sun almost every day of the year, even in the monsoon season.
This quick weather change makes weather forecast rather difficult and the predictions tend to be wrong most of the time. You can compare the following links to get an idea:
- Department of Meteorology of Sri Lanka: meteo.gov.lk -- shows forecast for several towns.
