Shipwrecks (Nusa Lembongan) Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming up for Nusa Lembongan. We’ve got a solid run of swell on the cards, but it’s a mixed bag of conditions, so you’ll want to pick your moments.

We kick off on Friday the 24th of July, but it’s pretty average. Shipwrecks is seeing a small, long-period SSW groundswell at 2 ft to 3 ft, with a period of 17 seconds. The wind is a cross-off from the SE at 16 mph, so it’s clean but not glassy. The wave energy is moderate (712), but the surf is marginal – probably not worth paddling out for anything special.

Saturday the 25th is a step up. The swell builds to 4 ft from the SSW, still with a long 15-second period, and the wind swings fully offshore from the ESE at 16 mph. This is a good combo – clean, lined-up waves. Energy is climbing (947). This is a solid morning session for the advanced crew.

Sunday the 26th gets bigger, but rougher. Swell jumps to 8 ft, but it’s from the SE with a short 9-second period. The wind is offshore at 19 mph, but it’s a fresh breeze. The wave energy is strong (1093), but that short period means it’s going to be a bit lumpy and less organized. Add in some rain showers, and it’s more of a challenge than a pleasure. This is getting into expert territory, and between the size and the wind, it might actually be more interesting for kite surfers than paddle surfing.

Monday the 28th and Tuesday the 29th are similar – 6 ft to 7 ft, short period (7-8 seconds), strong offshore winds at 19 mph. The swell is powerful (up to 720), but the quality is poor. Marginal surf, big onshore energy. Keep your board on the beach unless you’re after a workout.

Then we get a bit of a respite. Wednesday the 30th sees the swell drop to 4 ft, and the period lengthens back to 15 seconds from the SSW. The wind remains offshore. The energy is still high (1067), but the surf is still listed as marginal. Thursday the 31st is similar, with a smaller 3 ft to 4 ft swell, but the period stretches to 19 seconds – that’s a very long groundswell, which will be super clean and hollow on the reef. A standout for the patient surfer.

Now, here’s the real gold. On Friday the 31st of July, we get a beautiful run. The swell is a clean 3 ft from the SSW, 17-second period, with a moderate offshore wind from the SE at 16 mph. The energy is pumping (1162), and the conditions are described as “very good.” This is the pick of the near-term windows.

But the absolute standout of the whole forecast is Sunday the 2nd of August. We’ve got an 8 ft SSW groundswell with an 18-second period – that’s a proper, powerful groundswell. The wind is gentle offshore from the ESE at 9 mph in the morning, going to a moderate offshore in the afternoon. The wave energy is enormous (3107), and it’s described as “excellent” for experienced surfers. This is a serious day for the reefs. It’s a long-range call, so keep your fingers crossed, but if it comes together, it’ll be the best session of the run. The water temperature is about average for this time of year.

The following week is more of the same quality, with swell hanging around 5 ft to 6 ft, long periods, and light to moderate offshore/cross-off winds. It’s a consistent, high-quality pattern. By Saturday the 8th of August, the size drops back to 4 ft, and the energy fades, so the window is closing.

The standout session is the 2nd of August with that big, long-period SSW groundswell and gentle offshore wind. The 31st of July is a close second for a cleaner, smaller wave. Keep an eye on the tides, and don’t be late.

Rusty.
