Pererenan Surf Forecast and Surf Report

Alright, this is Rusty, and I’m looking at what’s on offer for the next couple of weeks here. I gotta be straight with you – it’s not a classic Bali run. The whole period is flagged as marginal, and there are no true blue-ribbon days. The problem is a persistent cross-shore wind that keeps things a bit chopped up, even when the swell has some size.

Let's start with the early window. Friday morning, we’ve got a solid 8ft SSW groundswell rolling in with a very long 16-second period. The combined wave energy is pumping hard (3528). But the wind is a cross-shore from the SE at 9 mph, putting a slight cross-chop on the surface. The afternoon stays similar, just a touch more onshore. It’s surfable for an intermediate, but it ain’t glassy.

Saturday, the swell drops to 6ft and then 5ft, but the wind stays a factor. We see a bit of relief on Monday morning, the 31st of August, when the wind goes cross-offshore from the ESE at 12 mph. The wave comment says “clean” for that session. With a 4ft, 18-second period groundswell, it’ll be a much nicer ride despite the smaller size. The energy is still decent (1367). That Monday morning is probably your best bet in this first week. Keep in mind the crowd at Pererenan, which is often busy, so get out early.

The first week of September rolls in with bigger swell. Tuesday the 1st has 7ft SW groundswell with 18-second periods and clean, cross-offshore winds in the morning. The energy is strong (2664). The size is getting up there for beginners, but for the experienced crew, this is the cleanest, most powerful window. The 2nd of September is similar, but the afternoon gets a little cross-chop.

After that, things taper off. There's a stretch from the 4th of September through the 6th where the swell drops below 5ft and the winds are messy. It’s a bit of a flat spell. The 10th of September is worth a mention: an afternoon show with 6ft of very long-period 18-second SSW groundswell, and the energy jumps back up to 2488. But it’s still cross-shore wind, so not a standout.

Now, for the far end of the outlook: Friday the 11th of September, we see another pulse of 8ft SSW swell (16 seconds) with clean morning winds (3506 energy). Again, cross-offshore. The morning session looks promising, but it's a long way out. The real eye-catcher is Saturday the 12th of September: a 10ft SSW groundswell with a very long 18-second period and massive energy (5302). The wind is a light cross at 9 mph, so there will be some chop. That’s big surf – expert territory only. But it’s two weeks away, so don’t bank on it just yet.

No single day here is a slam dunk. The Monday morning, 31st of August, is the most consistent small-to-medium clean option. The Tuesday morning, 1st of September, is the best combination of size and cleanliness for stronger surfers. The long-range Saturday the 12th of September is the biggest, but it’ll be a beast.

Rusty, signing off.
