Shipwrecks (Nusa Lembongan) Surf Forecast and Surf Report

Alright, Rusty here, givin' you the lowdown on Shipwrecks on Nusa Lembongan. This is a sheltered reef setup that only fires when the swell's right, and we've got a good run of it comin'. Water temp is about normal for this time of year, so nothin' crazy.

First few days are a mix, but we're building towards a proper sweet spot. Startin' Saturday the 25th and Sunday the 26th of July, we've got clean offshore winds, but the swell's a bit messy. Saturday morning sees a 4ft SSW groundswell with a long 15-second period, energy sittin' at 959 (moderate). The wind's a steady 25 km/h from the SE, blowin' offshore, so it'll be clean. Sunday, the swell jumps to 8ft from the SE with a shorter 9-second period, energy at 1108. The wind picks up to 30-35 km/h, still offshore, but that shorter period makes for more walled-up, less organized waves. It's fine for advanced guys, but not the best of the window.

From Monday the 27th through Wednesday the 29th, we hit a lull. The swell drops, wind stays offshore, but the quality's marginal. The period drops to 7-8 seconds on Tuesday, just weak, short-period windswell, not the kind that gets a reef break crankin'. Energy's down in the 600-800 range, tellin' you it's weak.

Now, here's the turn. Thursday the 30th of July starts showin' a pulse back, with a 4ft SSW swell and a long 15-second period, energy climbin' back up (1073-1212). Wind's still a steady offshore, so it's clean. But the real standout is Friday the 31st of July through to Sunday the 2nd of August. This is the window. Friday morning we get a 3ft SSW groundswell with a very long 17-second period, energy at 1267. The wind drops to 25 km/h, and it's glassy clean. Saturday the 1st of August gets even better: a 4ft to 5ft SSW groundswell, periods climbin' to 16 and even 18 seconds, energy jumpin' to 1622. The wind's a light 10-15 km/h from the ESE, makin' it perfect, clean conditions. This is classic, long-period groundswell, and at a reef like Shipwrecks, that means long, peelin' waves with power. Crowds are "sometimes" busy, so expect a few, but it's a long paddle and the long period means decent gaps between sets.

The absolute peak of the whole outlook is Sunday the 2nd of August. We're lookin' at a 5ft to 5ft SSW swell with a massive 20-second period. The combined energy is a big 2702, which is strong to very strong. The wind is a gentle to moderate offshore breeze, so the waves will be groomed to perfection. This is an expert-level setup, pure and simple. The long period means those waves will have a lot of power and will wrap beautifully around the reef. If you can handle the size and the paddle out, this is the best day of the whole run.

From Monday the 3rd of August, the swell stays solid, around 7ft from the SSW, but the period drops back to 16 seconds, and the wind picks up a bit. Still excellent, but that Sunday peak is the one to circle. Quality holds through the 4th and 5th with good, clean waves in the 5ft to 6ft range, before a nice new pulse arrives on the 6th and 7th of August with another 5ft to 6ft SSW swell and a solid 16-second period. The wind gets a little cross-offshore on the 6th afternoon and 7th, which could add a bit of texture, but it'll still be a fun, clean session. The 8th and 9th of August wrap things up with consistent 6ft to 7ft SSW swell, 15-second periods, and lighter winds. It's a slightly longer session, but the energy is still there.

So, the first week is a slow build, but the second week of the outlook, from Friday the 31st of July through to Sunday the 2nd of August, is the standout. Mark Sunday the 2nd of August as the big day for experienced surfers.

Rusty.
