Uluwatu Surf Forecast and Surf Report

Alright folks, Rusty here with the long-range look for our balmy little pocket of paradise.

We’ve got a ripper of a run ahead. The surf is on from the get-go and it’s going to stay that way for days, with just a bit of a sloppy middle stretch to navigate. This is all about Uluwatu. The dominant theme is consistent, clean, solid SSW groundswells, and the trade winds are locked in from the ESE, holding that famous offshore line. The water is sitting about average for this time of year, so no nasty surprises there.

Sunday, August 30th kicks things off with a clean 5 ft SSW groundswell. Southeasterlies are blowing 12 to 16 mph, keeping the wall glassy. The energy is moderate (839-924). It’s a fine start, a real nice warm-up.

Monday, August 31st is where it starts getting serious. The swell jumps a notch and the period stretches out to a long 18 seconds. We’re talking morning waves of 4 ft blowing out to 6 ft in the arvo, with that same clean offshore wind. Energy climbs into strong territory (1367-1892). For experienced surfers, this is the real deal. The long period from the SSW is pure gold at a point and reef setup like Uluwatu, giving you those long, freight-train walls.

Tuesday, September 1st is a bit of a weird one. The swell is up around 6 ft to 7 ft with a solid 17-18 second period, and the energy is pumping (2187-2320). But the wind goes a bit cross-offshore out of the SE, and the guidance flags it as marginal for tide. It’ll be big and powerful, but you’ll need to be on the right tide. This is for the crew who know the reef intimately.

Wednesday, September 2nd is much the same story through the morning – solid, cross-off, slightly tricky. But Wednesday afternoon the wind swings back to pure SE offshore, the swell settles a touch to 6 ft, and the conditions turn excellent. That afternoon session is the pick of the day.

From Thursday, September 3rd through Friday, September 4th, we get a beautiful run of moderate, clean surf. Swell holds around 5 ft to 5 ft, wind is 12 mph from the SE. This is perfect intermediate-to-advanced fun, consistent and tidy.

Saturday, September 5th sees another pulse of SSW groundswell arrive, pushing back up to 6 ft - 6 ft. The wind stays clean offshore. Energy is strong (1044-1244). Another one to circle.

Now, Sunday, September 6th is a day of two halves. The morning is absolute magic: a long 18 second SSW swell at 5 ft with a gentle 9 mph SSE breeze, making for glassy, clean perfection. This is a standout. The energy reading hits 2400 – that’s serious power from that long period. But the afternoon turns the corner: the swell jumps to 8 ft, the wind swings cross-off, and the forecast flags tricky tides again. It'll be a beast.

Monday, September 7th and Tuesday, September 8th morning remain a bit cross-off and tricky with that big, powerful swell in the water. You’ll need to pick your moment.

Tuesday, September 8th afternoon the wind goes pure offshore again. The swell is 6 ft with a very long 19-second period. The energy is huge at 2736. Get on it. For the advanced crew, this is gold.

Wednesday, September 9th is the absolute apex. Morning brings an 8 ft SSW groundswell with clean offshore wind and energy readings through the roof at 3296. This is big, powerful, expert-only territory. The surf will be thumping. If you are a charger, this is your day.

Thursday, September 10th stays excellent but drops back a notch. Clean offshore wind, 7 ft to 6 ft swell, still great energy. The Friday, September 11th and Saturday, September 12th period eases into that perfect sweet spot: 5 ft to 5 ft, clean, consistent SSW swell with periods around 14-15 seconds. This is Uluwatu at its most user-friendly for experienced surfers.

Sunday, September 13th and Monday, September 14th continue that same beautiful trend: 5 ft, clean, gentle offshore breeze, excellent conditions. A fantastic way to wrap the run.

If I had to call it, the absolute standout windows are Monday, August 31st for the start of the long-period juice, and then Wednesday, September 9th for the biggest, cleanest swell of the run. For the all-rounder, the stretch from Thursday the 10th through Monday the 14th is just consistent, high-quality Uluwatu.

Get amongst it.
