Keramas Surf Forecast and Surf Report

Alright, Rusty here. Let's have a look at what Bali's got cooking for us.

Alright, this is a classic Keramas story. We've got a serious, consistent groundswell train lining up from the SSW, and it is going to be a long one. The main player across this whole outlook is a solid, long-period SW groundswell, with periods often hitting 16 to 18 seconds. That’s proper energy.

We kick off straight away on Tuesday, August 11th. The surf is already pumping. We’re looking at a dominant 10 ft SSW swell with a 16-second period rolling in. The wave energy is absolutely firing, reading at 5773. That is a lot of juice. The wind is light and offshore from the SSE at 9 mph, so Keramas is going to be clean and well-shaped. The water is sitting at about 81°F, which is pretty darn average for this time of year – nothing unusual there. Tuesday afternoon is a standout, no doubt.

But hey, there's a catch. The wave comment flags "marginal surf forecast or questionable tide conditions" for Tuesday. A 10 ft swell on a reef like Keramas with a 16-second period is a serious swell, and it’s going to be well overhead. Surf at this size is pushing into expert-only territory for many, over 8 ft.

Heading into Wednesday, August 12th, the swell drops a touch, down to 8 ft in the morning and 6 ft in the afternoon, but the period remains long. The wind switches to a cross-onshore from the SE, which puts a bit of texture on the waves. It's still surfable, but not as clean as Tuesday. The energy readings are still strong, in the 1800 to 3000 range.

Thursday, August 13th, we see a bump back up, with 8 ft SSW swell in the morning and afternoon. The wind goes back to an offshore flow from the SE, which is better. But again, the "questionable tide" note pops up for all sessions through this whole period.

Through the rest of the first week and into the second, the swell stays consistent. From Friday, August 14th, all the way through to Monday, August 25th, we see a steady diet of 5 ft to 7 ft SSW swell, with periods staying long. The wind is mostly a gentle cross-onshore breeze from the SE, which keeps the wave faces a little bumpy but very ridable. Energy remains moderate to strong, usually in the 1500 to 2900 range.

The standout in all of this? It has to be that Tuesday, August 11th. A clean, offshore 10 ft groundswell with massive energy is a rare treat. For the rest of the run, it’s just consistent, solid, reliable Keramas reef-break action. Remember, with these long-period swells, expect clean, powerful lines at this reef, with longer lulls between sets. It’s a consistent spot, so you won't be waiting long.

Expect some crowds, as this place is "sometimes" busy, but with so much swell on offer, there should be waves for everyone who can handle it.

This is going to be a solid run of surf. The only real bummer is that "marginal tide" note hanging over everything, so check your charts. But the swell is there, and it’s not going anywhere.

Rusty.
