The dry season, roughly April to October, is the best time for Canggu. Rain is rare, and mornings usually bring light offshore winds, so Batu Bolong, Echo Beach and Pererenan are at their cleanest before the trade winds pick up mid-morning. Bali's weather agency put the 2026 dry-season peak in August. July, August and the Christmas to New Year weeks are the busiest, so book villas early and expect the worst traffic of the year.
From November to March showers arrive most days, often as heavy afternoon or evening downpours, and January and February are usually the wettest months. Winds swing to the west and blow onshore, so the west-coast waves turn messy and water quality drops near river mouths after heavy rain. The same monsoon washes plastic onto the beaches from about October to March. In exchange, villa prices and crowds ease, apart from the holiday weeks.
Nyepi, the Balinese Day of Silence, closes the whole island for 24 hours, airport included; in 2027 it falls on Monday 8 March, with Idul Fitri two days later, so expect busy roads and domestic travelers either side. In the days before Nyepi, temple congregations walk to Batu Bolong and the other beaches for Melasti purification rites, and on Nyepi eve the banjars parade ogoh-ogoh effigies through the streets. Roads close for both, so plan around them.
