Shipwrecks (Nusa Lembongan) Surf Forecast and Surf Report

G’day, Rusty here. We’ve got a solid run of surf lining up at Shipwrecks on Nusa Lembongan. This is a reef setup for advanced crew only, and it’s a consistent wave that likes a solid SSW groundswell. The water’s sitting at a warm 80°, which is pretty much average for this time of year, so no nasty surprises there.

The energy kicks off Thursday afternoon, August 13th, with a strong 8 ft SSW swell riding a long 16-second period. The combined energy is pumping at 3529—that’s serious power. Winds are a moderate offshore from the SE, keeping things clean and lined up. This is expert territory right from the get-go; that size and period will have those reefs unloading.

Friday the 14th backs it up nicely. Morning brings 7 ft SSW swell with a gentle cross-offshore breeze, still clean. Afternoon drops a touch to 6 ft, but it’s a little more marginal on the tide. Saturday the 15th is a standout: morning offshore winds with 7 ft SSW swell and a very long 17-second period, energy sitting at 2378. These long-period groundswells at a reef setup like Shipwrecks—this is where it gets proper. Long gaps between sets, but the shape will be unreal. Afternoon stays solid at 7 ft.

Sunday the 16th remains clean and solid through the morning with offshore winds and 6 ft SSW swell. Monday the 17th drops to a more manageable 4 ft, but still clean with offshore breezes. Tuesday the 18th is a gem: light offshore winds, 4 ft, but that period jumps back to 16 seconds and energy is 1638—it’ll feel bigger than the face height suggests.

Wednesday the 19th is the real highlight. Morning brings a crisp 7 ft SSW groundswell at a very long 18-second period, light offshore wind, energy at 2784. This is proper quality. Afternoon holds at 7 ft with a 3032 energy reading and offshore breeze. For experienced surfers, this is as good as it gets. Thursday the 20th follows with 8 ft SSW, still offshore, still clean—another big day for the advanced crew.

Friday the 21st has morning at 6 ft with stronger offshore winds, afternoon drops to 5 ft but that period stretches to 18 seconds again and energy jumps to 2240. Good stuff. Saturday the 22nd keeps the 7 ft SSW running, clean in the morning. Sunday the 23rd settles back to 5 ft, still fun.

For the second week, it stays rideable but tapers off. Monday 24th and Tuesday 25th are smaller, around 4 ft to 4 ft, but still with clean offshore breezes. Wednesday 26th picks up a touch to 5 ft, and Thursday 27th brings 6 ft SSW. Friday 28th fades with 6 ft but cross-off winds and more marginal conditions. Still plenty of waves to go around, but the real fire’s in that first week.

If you’re an expert and you want the pick of the litter, aim for Wednesday August 19th or Thursday August 20th—big, clean, long-period SSW groundswell with offshore winds. That’s the call.

Rusty.
