“You can’t stop the waves, but you can learn to surf” — Jon Kabat-Zinn
The official peak surf season in the south-west, around Welligama, is from the end of October to early April. Winds are offshore making clean waves, swells are consistently good and rain is at a minimum. The season then shifts up the south east coast towards Arugum Bay from April. Waves cater for all surfing abilities. You can rent long and fish boards both locally – handy as it is unlikely they will let you on your plane with you long-board. Outside the official surfing season you still get some fantastic days in the water or you can jump in on the kite boarding season when the consistent winds trump the consistent swells.
Of course you can roll out of bed and spend a day in the sun on a pristine sandy beach, bathing in azure warm waters. South Sri Lanka is big on beaches, it is also big on wellness and there are some other great chill outs.
