Rain season
Galle on Sri Lanka's southern tip takes a direct hit from the southwest monsoon (May–September), which is the dominant rainy season here. The city receives over 2,500mm annually, with June the single wettest month. The northeast monsoon brings less rain to the south than to the north. Short dry spells occur in January–March, making it the preferred season for coastal visitors.
