Sejorong Surf Forecast and Surf Report

G’day, Rusty here. Looks like we’ve got a tricky run ahead at Sejorong. The first few days are all a bit messy with cross-shore winds and that moderate chop, so don’t expect much to start with. The swell is solid but the conditions just aren’t cooperating. We’re waiting a fair while for anything worth getting excited about.

Alright, let’s get into it. Thursday the 20th of August kicks things off with an 8ft SW swell running at a long 16 seconds. The combined energy is sitting at 3723 – that’s strong wave energy, no doubt. But the wind is cross from the southeast at 9 mph, so expect slight cross-chop. The water’s sitting at 79°, bang on average for this time of year, so no surprises there. But the reports keep calling it marginal, and with that cross-breeze, it’s just not coming together clean. Thursday morning is your best shot that day, but it’s still only a so-so wave.

Friday the 21st, the swell drops a touch to 6ft in the morning from the SW at 15 seconds, but the wind picks up to 12 mph cross-shore, adding more chop. Afternoon sees a 8ft SW swell with a 17-second period – nice and long – but again, that cross-wind messes it up. The energy is strong at 3294 in the afternoon, but the quality just isn’t there.

Saturday the 22nd and Sunday the 23rd are more of the same: 7ft to 7ft SSW swells, 15–16 seconds, cross-winds at 12 mph. Sunday afternoon the wind backs even more cross-onshore, making it choppy and poor. Not worth paddling out.

Monday the 24th and Tuesday the 25th keep the pattern going – 6ft to 7ft SSW swell, moderate cross-shore wind, energy dropping from 1982 down to 1439. Still marginal, still chop.

Wednesday the 26th morning goes cross-onshore again, then the swell drops to 5ft and energy falls to 882 – weak stuff. Thursday the 27th is properly poor, with 3ft to 3ft swell and cross-onshore wind. That afternoon period has a 20-second groundswell but the energy is only 1511, and the wind kills it.

Friday the 28th of August shows a bit of life – 8ft SSW swell, 16 seconds, combined energy of 3395. But the wind is cross-onshore at 9 mph in the morning, so it’s choppy. The guides call it marginal, and I’d agree – if you’re desperate, maybe a dawny, but don’t expect perfection.

Now, the standout in this whole 16-day window – and I mean the only real one – is the 1st of September. Tuesday morning sees a solid 10ft SW swell with an 18-second period, combined energy of 5359 – that’s strong, meaty groundswell. The wind is light cross-onshore from the SSE at just 6 mph, so it’s nearly glassy with just small wind ripples. That’s clean enough to make this a proper session for experienced surfers. 10ft is expert territory, so leave the logs at home and bring a step-up. The water’s still around 79°, normal for the season. This is the one to pencil in, but remember – it’s way out on the 1st of September, so treat it as promising but not locked in.

After that, the 2nd of September drops to 7ft SW swell, light winds again, but nothing special. From the 3rd and 4th of September, it fades into poor conditions and smaller swells with onshore wind. The run ends weak.

Honestly, Sejorong is an inconsistent spot – it doesn’t always line up – and this forecast is a long stretch of marginal surf with a lot of chop. But that early September window with the 10ft SW groundswell and light wind is the only time I’d point the car that way. Keep your eyes on that one.

Rusty.
