Coragi Surf Forecast and Surf Report

Alright, let’s get into it. The first few days of the run are where the magic is. We’ve got some proper groundswell and clean, offshore winds lined up, and it’s going to be a fun one. Water temp is sitting at 82°, which is just a touch warmer than we usually see, so you can leave the booties at home.

We kick things off on Monday the 17th at Coragi (Big Island). This reef break is about as reliable as they come. The morning starts with a 3ft south swell with a 16-second period—that’s real groundswell. The wind is offshore from the northeast at 12 mph, and the ocean is looking glassy. The energy is sitting at 759, so there’s some good power behind it. This is the standout session. In the afternoon, the swell bumps up a touch to 3ft from the south, and the offshore breeze holds. Monday is the day to be in the water.

Tuesday the 18th keeps the quality high. Morning sees a 4ft SSW swell with a 14-second period. Energy is up to 972, so there’s a lot of push. Winds stay offshore from the NE at 12 mph, and it’s clean all day. Another cracker of a day.

Wednesday the 19th, the swell holds at 5ft from the SSW, with a 15-second period in the morning. The wind goes a bit cross-offshore from the NE, but it’s light at 9 mph. Still clean, still good shape, just not quite as perfect as the previous two days.

Thursday the 20th is a different story. The morning shows a bigger 7ft swell from the SSE, but the period drops to a short 9 seconds. The energy is strong at 1096, but that short period means it’s going to be less organized and more chaotic. The wind is cross-offshore, so it might be okay for the experts, but this is real deal stuff. By the afternoon, the wind goes onshore from the SSW and the swell drops to 4ft. Conditions will go to mush, so that’s a write-off.

Friday the 21st, the swell drops back to a cleaner 3ft from the SSW with a 12-second period. Morning winds are light offshore from the north at 9 mph, and it’s clean and small. The afternoon, the wind picks up to 19 mph from the north. It’s still offshore, but that’s a fresh breeze and it’ll chop things up a bit.

The weekend, the 22nd and 23rd, brings more small, clean surf in the 3ft to 3ft range with 11-12 second periods. Offshore winds from the NNE continue. It’ll be fun on a longboard, but nothing to get too excited about. The energy is starting to fade.

From Monday the 24th onward, the swell gets smaller and the period drops. We see a pulse on the 25th with a 3ft swell, but the period is only 8 seconds, so it won’t have any shape. The winds stay mostly offshore, so it’ll be clean, but it’s going to be small and weak. The end of the month and the 1st of September are looking pretty flat and uninspiring. There is a bit of an energy spike on the 27th, but the winds turn onshore and kill it.

So, here’s the takeaway: your window is the first part of this forecast. Monday the 17th and Tuesday the 18th are the clear standouts. That’s when you need to be out there. The rest of the run is pretty average and small, with the surf going quiet by the end of the month. That 7ft on Thursday morning is for experienced surfers only—it's too much for beginners.

Also, remember Coragi is a reef, and it handles that longer period swell beautifully. The crowds are listed as “sometimes,” so you might see a few others out, but it shouldn’t be packed.

That’s how I’m reading it. Get on it early.

Rusty.
