Shipwrecks (Nusa Lembongan) Surf Forecast and Surf Report

Alright, Rusty here, and I’ve been staring at the charts for Nusa Lembongan. This is a rare run – we’ve got a solid, consistent block of swell aimed right at the island’s sheltered reefs, and the wind is playing ball. The water is sitting at 81°, which is pretty much spot on for this time of year, no weird anomalies to worry about.

The standout is Shipwrecks. It’s a consistent, sheltered reef, so it handles the size without getting too gnarly. The action kicks off Monday 3rd August with a clean 5ft SSW groundswell (15 seconds) and light offshore winds. The combined energy is already pumping at 1108, and it only gets better. By Thursday 6th August, the swell builds to 6ft, period stretches to 17 seconds, and the offshore wind firms up – energy jumps to 2050. This is the sweet spot for experienced surfers looking for long, clean lines.

But the real highlight is the week that follows. From Friday 7th August through to Monday 10th, we see swell heights holding around 7ft to 8ft, with a very long period of 17-19 seconds and consistent offshore breezes. The energy readings are massive – 2630 on Friday morning, and peaking at a whopping 3846 on Monday afternoon. This is clean, powerful, open-ocean groundswell hitting a reef setup. It’s big enough that beginners should stay out, but for anyone with experience, this is about as good as it gets.

Keep an eye on Sunday 9th – there’s a chance of rain showers in the morning, and the wind swings cross-offshore in the afternoon, which might make the surface a little lumpy but still rideable. The quality remains high through the middle of the month, with another standout on Thursday 13th August – a solid 10ft S swell, 18-second period, and gentle offshore winds. Energy is through the roof at 5320. That’s a serious day for experts only.

The last few days, from 15th to 18th August, the swell drops back a bit but the wind stays offshore, so the waves will be clean and lined up, just smaller. Even on the 16th, with 4ft to 4ft, the period is still long enough to keep the shape good.

No gaps to speak of here – it’s a solid 16-day run with clean conditions and consistent swell. If you’re on the island, get your quiver ready.

Rusty.
