Go now while the offshore trades lock the faces clean and the swell wraps in at its best angle. Kuta Reef is running 3 to 5 metres overhead, backed by a long 17-second groundswell period that will hold shape across the 800-metre paddle out. The tide is barely moving and still rising into the sweet spot; water is 28°C and the wind is 6 kilometres per hour from the east-south-east, holding the walls crisp. This is a wave for confident, experienced surfers only. The window holds cleanest until around noon.

By mid-afternoon the south-easterly wind swings onshore and fills to 19 kilometres per hour, turning the faces choppy and cross-shore. The swell size holds firm at overhead high, but the quality drops away as the wind deteriorates the shape.

Tomorrow peaks at the same overhead-high scale, probably 2.4 to 5.4 metres, and returns to epic across the morning before the same south-easterly wind spoils the afternoon. The read is as firm as these forecasts get, though the ocean will decide the exact rhythm and where the biggest sets line up. Tomorrow offers another confident session in a window that opens early and tightens as the day goes on.
