Uluwatu Surf Forecast and Surf Report

Alright folks, Rusty here. We’ve got a solid run of surf ahead at Uluwatu, and it’s shaping up to be a classic stretch. This is a reef and point setup that’s very consistent, exposed to the swell, and it’s an advanced crew only for the most part. The water’s sitting at 79°, which is pretty much bang on average for this time of year, so no surprises there.

The whole outlook kicks off Saturday morning, 5th September, with a solid SSW groundswell pushing through at 6ft, riding a 16-second period out of the SSW. The combined energy is pumping at 1826 (strong to very strong wave energy). The wind is offshore from the SE, blowing at 12 mph, so the lineup is going to be clean and well-shaped. This is a standout session for the experienced surfer – big, powerful, long-period swell that’ll really light up the reef. It’s a bit too big for beginners, so leave it to the guys who know what they’re doing.

Saturday afternoon holds the same quality, with the swell nudging up to 7ft, still with that long 16-second period and clean offshore wind. The energy jumps to 2028 (strong to very strong). Sunday morning, 6th September, is probably the best of the bunch early on. Swell is 7ft from the SSW, but the period stretches to 17 seconds, and the combined energy rockets to 2844 (very strong wave energy). The wind is still offshore, clean, and glassy. That’s a proper groundswell day – waves will have serious push and shape, but with that long period, it might be a bit too straight at the main peak, so keep an eye on the rip bowls.

Monday the 7th keeps the quality high with 7ft SSW swell, 14-second period, and offshore winds all day. The energy is still strong (1844). Tuesday the 8th sees a slight drop in quality – the wind goes cross-offshore, and the swell drops to 5ft in the morning, though the period is a massive 19 seconds, giving an energy of 2774. The afternoon picks up to 6ft. It’s still clean, but the cross-off wind will make it a bit more technical.

Now, Wednesday the 9th is where we hit the real standout. Morning session sees 8ft SSW swell, 16-second period, with a gentle offshore breeze at 9 mph. The combined energy is a massive 3182 (very strong). This is a heavy, powerful day – only for the experts. The waves will be big, clean, and well-formed. If you’re an advanced surfer and you’ve got the skills, this is the session to circle. The afternoon drops slightly to 8ft, still excellent.

The rest of the first week and into the second week is a constant stream of good surf. Thursday the 10th through to Sunday the 13th delivers solid 5ft to 8ft SSW and SW swell, with periods mostly between 14 and 18 seconds. Winds stay offshore or gentle offshore, keeping the lineup clean. The energy is consistently strong to very strong, with the 13th September afternoon peaking at 3087.

Monday the 14th to Wednesday the 16th brings a bit more wind, with ESE winds at 16 mph, but still offshore. The swell stays in the 5ft to 7ft range, with periods of 15 to 17 seconds. It’s still excellent, but the wind gets a bit more punchy. Thursday the 17th and Friday the 18th hold strong with 7ft to 7ft SSW swell, long periods, and clean offshore winds – more top-tier sessions.

The final weekend, Saturday the 19th and Sunday the 20th, starts to dial back a touch. Saturday has 5ft to 6ft SW swell, still clean. Sunday the 20th sees a bit of cross-off wind in the morning, but the afternoon comes back with a 7ft SW swell, 16-second period, and a gentle offshore breeze – a solid way to close out the run.

Overall, the best of the best is Wednesday the 9th morning for the biggest, most powerful waves, and Sunday the 6th morning for that incredible 17-second period groundswell. Expect crowds at Uluwatu – it’s always a popular spot, so get there early for a peak.

Rusty.
