Shipwrecks (Nusa Lembongan) Surf Forecast and Surf Report

Alright, Rusty here again, this time in feet and miles. Let’s talk about what’s on the menu.

We’ve got a single reef break that’s going to be the focus for the next couple of weeks. Water temp is sitting at 81°F—right around normal for this time of year, nothing to write home about.

The first real action starts Sunday the 6th. Swell is 5ft from the SSW, period at 16 seconds—that’s proper groundswell. Wind is cross-off from the SSE at 12 mph, keeping things clean. Combined energy is 1755, so we’re already into moderate-to-strong territory.

Monday the 7th, morning swell pushes to 6ft, still SSW, period at 14 seconds. Wind stays cross-off at 12 mph. Afternoon sees the wind drop to 9 mph, swell at 6ft, and conditions are clean and inviting.

Tuesday the 8th is where it gets real. Morning has 7ft SSW swell, 13-second period, and energy jumps to 2517. That’s strong. Wind is still a gentle cross-off. Afternoon is even better: 5ft but the period stretches to 18 seconds, and energy hits 2879. That’s the session to circle—long, lined-up waves, clean faces, and manageable crowd levels.

Wednesday the 9th keeps the quality. Morning sees 8ft SSW, 16-second period, energy at 2588. Wind goes lighter in the afternoon—just 6 mph from the south—so the reef will be glassy and fast. That afternoon with 7ft and near-calm wind is another standout.

Thursday through Saturday, we’re looking at 4-6ft SSW swell, 14-16 second periods, and cross-off winds holding. Energy stays in the 1400-1800 range, so still solid.

Sunday the 13th through Tuesday the 15th, the swell settles to 4-6ft, and we get some true offshore windows—Sunday and Tuesday mornings show clean offshore wind from the SE at 9-12 mph. Those mornings will be glassy and lined up. Energy drops but remains moderate.

Wednesday the 16th and Thursday the 17th see the swell ease to 3-5ft, but the offshore mornings keep things tidy. By Friday the 18th, the swell bumps back up to 6ft with light cross-off winds and energy at 1429.

Saturday the 19th is another top pick. Morning has 6ft SW swell, 18-second period, and combined energy of 2101. Wind is light from the SSE at 6 mph—near glassy. That’s a serious session for experienced surfers.

The final days, Sunday the 20th and Monday the 21st, taper off. Swell drops to 4-5ft, energy falls to 556-1385, and conditions stay clean but less exciting.

Best bets: Tuesday afternoon the 8th and Saturday morning the 19th. Both have long-period groundswell, solid size, light wind, and strong energy. This reef will produce fast, racy walls—expert territory once it’s over 5ft, and at 7-8ft, it’s for the skilled crew only. The long period means sets are spaced out, so paddling out is easier, but the waves themselves will be powerful and demanding.

Crowds are listed as “sometimes,” so you might have to share, but pick your tide and you’ll find some room.

Keep your eyes on the horizon and your wetsuit zipped.
