Traveller notes on Mirissa in November
Other months in Mirissa
Mirissa's forum calls February close to ideal — fewer crowds, good weather, and prime whale-watching season, which regulars say runs November through April. Sightings aren't guaranteed (recent reports put the odds around 50%), though dolphins show up far more reliably; tours head out around 6:45am, and regulars say the earliest departure gives the calmest seas and the best shot.
