Shipwrecks (Nusa Lembongan) Surf Forecast and Surf Report

Alright, Rusty here. Let's look at what's on the table for the Lembongan area.

We're looking at a solid run of trade wind swells, and the spot that's got our attention is Shipwrecks (Nusa Lembongan). The water’s sitting at a warm 81°F, which is a little toastier than the average for this time of year, so you'll be comfortable in boardshorts.

The pattern kicks off strong and just gets better. We start with a clean 4ft SSW groundswell on Sunday morning, with a period of 13 seconds and a gentle offshore breeze from the ESE. The combined energy is moderate (746), and it's glassy. That afternoon the wind picks up a knot but stays offshore, with the swell holding steady at 4ft. Monday morning sees the swell dip a fraction to 4ft, but the period jumps to a very long 18 seconds, and the energy climbs to 974. The wind is still a clean offshore from the SE. But Monday afternoon is where it starts to get serious – the swell pushes to 5ft, still with that long 18-second period, and the energy jumps to 1325. The wind is moderate offshore, and conditions are very good.

Tuesday (1st September) is the first real standout. Morning brings a solid 6ft SSW groundswell with an 18-second period. The wind is a steady 15 mph offshore from the SE, and the energy is pumping at 1682. This is a proper groundswell with serious shape. The afternoon shifts to a cross-offshore wind, but the swell stays at 6ft.

Wednesday and Thursday are still very good, with 5ft and 4ft swells, clean mornings, and a moderate offshore breeze. The energy stays in the moderate-to-strong range. Friday and Saturday (4th and 5th) see the swell drop a little and the wind goes cross-offshore, but the surf is still clean and rideable. Saturday afternoon, the energy picks back up to 1065 with a 4ft swell.

Now, here's where it gets really interesting. Starting Sunday (6th September) , the energy explodes. We see a 5ft swell with an 18-second period and a combined energy of 2195 – that's strong. The wind is cross-offshore, but the power is immense. Monday (7th) sees 7ft surf with a 14-second period, and the energy is 1678. This is getting into expert territory.

Tuesday (8th September) afternoon is the absolute standout of the entire run. The swell hits 7ft from the SSW with a 16-second period, and the combined energy is a massive 3067. The wind is a light 9 mph cross-offshore from the S. This is excellent, powerful surf for experienced surfers only. The sets will be long and lined up.

The energy stays very high into Wednesday (9th) with 7ft surf and 2386 energy. The wind goes cross-shore, so it might be a bit lumpy, but the power is there. Thursday (10th) is a good day to recover with a 6ft swell and a light offshore breeze. Then Friday (11th) morning is another standout: a 5ft SSW groundswell with a massive 20-second period. The energy is 2589, and the wind is a clean offshore from the SE. This is a proper, long-period groundswell for the reefs and points.

The run continues through the weekend and into the following week, with swells between 5ft and 7ft, and energy readings staying well above 2000. The wind is consistently cross-offshore or light offshore. This is a fantastic, extended period of quality surf. The whole period is a go, but if you're picking one moment, it's Tuesday the 8th afternoon for the sheer power, or Friday the 11th morning for the silky, long-period lines.

Rusty.
