Pererenan Surf Forecast and Surf Report

G’day, Rusty here. We’ve got a mixed bag ahead at Pererenan (Bali). This stretch is a beach and reef set-up, exposed to the south-west swell. It’s consistent, but a lot of this run looks more like a battle with cross-shore wind than anything truly firing. The water’s at about 79°, pretty much normal for this time of year.

First up, Thursday afternoon 13th August we see solid swell: 10ft from the SSW with a very long 16 second period. The combined energy is strong, at 4161. Offshore ESE wind at 12 mph keeps things clean. This is expert territory – over 8ft – and with that long period, it’ll be better on the deeper reef sections than the beach breaks. It’s the standout of the first week, but only for those with serious experience. Crowds are often around here, so expect company.

Friday 14th and Saturday 15th sees the swell drop to 7ft to 8ft, still long period from the SSW. Wind swings to SE and goes cross-shore, so the surf gets a bit chopped up. The energy stays moderate to strong – 2725 on Friday morning, 3217 on Saturday afternoon. Still clean conditions are gone, so it’s more of a grunty, lumpy session for intermediates.

Sunday 16th August eases to 6ft in the afternoon, but with that cross-shore wind and moderate energy (1619), it’s nothing special.

Then a really nice window appears on Tuesday 18th August. The afternoon shows 6ft from the SW, 16 second period, clean with an ESE cross-off breeze at 9 mph. The combined energy is strong at 2577, and conditions are marked as excellent for experienced surfers. This is your second standout – more manageable size, still plenty of power, and clean faces. Over 5ft, so beginners might find it a bit much, but advanced surfers will love it.

Wednesday 19th August afternoon is also promising: 8ft from the SSW, 18 second period, very long, and clean with cross-off ESE breeze. Energy is very strong at 4374. Again, this is expert-only size, and the long period means the reef will be the go.

From Thursday 20th onward, the swell hangs around 6ft to 8ft but the cross-shore wind becomes more persistent. There are flashes of clean conditions on Friday 21st morning and Thursday 27th August morning, but nothing that jumps out as a true standout. The energy starts to drop into the moderate range from the 24th onward, and by the 25th, the swell dips to 3ft with a long period of 17 seconds – weak energy at 1191, not worth getting excited about.

The second week from around the 22nd to the 27th is mostly moderate swell, cross-shore wind, and just average conditions. There’s a clean window on Thursday 27th August morning with 6ft from the SSW, but it’s not a standout. The energy is moderate at 1798, and it’s more of a solid average session than anything memorable.

All up, the best two bets: Thursday 13th August afternoon for experts after a big clean groundswell, and Tuesday 18th August afternoon for solid clean surf for experienced surfers. The rest is background noise.

Stay safe out there. Rusty.
