Uluwatu Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of swell ahead for Uluwatu, and it’s looking like a proper extended season for the experienced crew. This is a consistent, exposed reef and point setup, and the forecast is serving up a long stretch of clean, offshore conditions.

The water temp is sitting about average for this time of year, so a standard tropical warmth – nothing to write home about, just your usual comfortable bath.

We’re kicking off on Thursday, 27th August. Morning starts with a clean 4ft SW groundswell rolling in at a long 16 seconds, with a moderate ESE offshore breeze. The wave energy is already pumping at a solid 1330 (moderate), and the sets are going to be clean and lined up. By the afternoon, the swell bumps up to 5ft from the SSW, with a gentle offshore from the SE, keeping the face glassy. 2872 on the energy reading – that’s punching well into the moderate range.

Friday, 28th August, is where things really start to cook. Morning sees a proper 8ft SSW swell, period still holding at 16 seconds, and a moderate offshore breeze. The energy jumps to 3592 (strong). That’s a solid wave for advanced surfers only. The afternoon holds the same 8ft size, with a gentle cross-offshore breeze, keeping it clean.

Saturday, 29th August, the swell eases back a touch to 6ft, but the wind goes almost glassy with a slight SSE breeze. Energy is still good at 1529. The afternoon picks up a clean 5ft SW swell with a gentle offshore. Both sessions are excellent.

Sunday, 30th August, the swell drops to 5ft in the morning, period shortening to 13 seconds, but the offshore wind is still present. The combined energy is a more moderate 976. The afternoon brings a 4ft SSW swell with a 12-second period, but the energy picks up to 1047. Still clean.

Monday, 31st August, the period jumps back up to 18 seconds – that’s a very long-period groundswell for the 4ft morning swell. Energy is 1362. In the afternoon, 6ft at 18 seconds, energy 1870. Both runs have a moderate offshore breeze. With that long period, expect longer lulls between sets, but the waves will be powerful and well-shaped, perfect for the reef and point setup here.

Now, Tuesday, 1st September, the morning is a bit of a mixed bag. The swell is 7ft from the SW, period 18 seconds, but the wind is cross-offshore. The score is lower here, indicating it might be a bit tricky with the tide. The afternoon brings a fresh offshore breeze at 19 mph, with the same 7ft SW swell, period 17 seconds, energy 2340. The wind is strong but offshore, so it will be clean, but you’ll want to be on your game.

The rest of the first week and into the second week keeps a steady rhythm. Wednesday, 2nd September, through to Saturday, 5th September, sees consistent 4ft to 5ft SSW to SW swells, all with moderate offshore winds. Energy stays in the moderate range (661 to 1143). It’s a reliable, clean run.

Then we get a real standout building for the second week. Sunday, 6th September, the swell jumps back up to 7ft from the SSW, period 16 seconds, with a gentle offshore breeze. Energy is 2062. That’s a cracking day. Monday, 7th September, eases to 6ft, but it’s still clean.

But the real highlight is the peak we’re seeing from Tuesday, 8th September, through to Friday, 11th September. Tuesday morning starts with 8ft SSW swell, building to 8ft on Wednesday, 9th September, and holding that size through Thursday, 10th September. Periods are 14 to 16 seconds, and the winds are offshore – moderate on some days, gentle on others. The energy readings are massive: 2286, 3157, 3620, 3378 – all strong. This is a long-range standout, so it’s promising but not locked in yet. For the experienced crew, these are the days to circle. The swell is over 8ft, so this is expert territory only. Friday, 11th September, eases to 7ft, still with a gentle offshore.

Bottom line: Uluwatu is firing for the next 16 days. The best of the best is the stretch from 8th to 11th September, with that big, clean groundswell. The early part of the forecast is also excellent, especially Friday the 28th. Crowds are a given here – it’s always busy, so plan your paddle-outs accordingly.

Rusty out.
