Off The Wall Surf Forecast and Surf Report

Alright, Rusty here, and we're looking at Off The Wall on the North Shore of Oahu. This is a heavy, fast reef slab—not for beginners, not for the faint of heart.

The first couple days are ugly. Monday the 17th is blown out with messy cross-onshore wind and a lumpy 8 ft swell from the WSW. Kite surfers might have a look, but for paddle surfing it’s a no-go.

Tuesday the 18th morning cleans up. Cross-off wind, 7 ft from the SW at 12 seconds, clean and lined up for the experienced crew. Moderate wave energy (1857). Afternoon bumps to 10 ft—expert only, still clean, and energy jumps to 2596.

Wednesday the 19th stays clean: 8 ft in the morning, 8 ft in the afternoon, both SW at 12 seconds. Good shape, not the standout.

Then we hit Thursday the 20th morning. This is it for the first week. 12 ft from the SW at 13 seconds, clean cross-off wind, and a combined energy reading of 3425. Powerful, thumping, and loaded. Afternoon holds at 10 ft but wind picks up, so the morning is the call.

Friday the 21st fades fast. 7 ft in the morning, energy dropping to 1442, then 5 ft by afternoon. Still clean but small.

Saturday the 22nd morning is a quiet gem. Near-calm wind, clean 7 ft SW swell at 11 seconds. Crowds are possible, but if you’re early, you might score a few alone.

Sunday the 23rd morning brings another solid pulse: 7 ft from the SSW at 12 seconds, clean, strong energy (2504). The afternoon goes to 14-second period but wind picks up.

Monday the 24th morning has offshore wind and 7 ft from the SSW at 11 seconds. Clean and crisp. Afternoon drops to 4 ft but with a 14-second period, still clean.

Now, circle Tuesday the 25th. Morning shows 3 ft but with a 24-second period—incredibly long, glassy. The afternoon is the bomb: 8 ft from the SW at a 20-second period, light wind, glassy, and an energy reading of 5640. That is exceptional. For experts only. This is the day.

Wednesday the 26th afternoon goes completely glassy. Zero wind, 7 ft SW at 14 seconds. Smooth as butter.

Thursday the 27th is another clean, solid day with offshore in the afternoon: 7 ft SW at 13 seconds, light breeze. Consistent quality.

Friday the 28th gets messy with cross-onshore wind and lumpy 7 ft. Skip it.

Saturday the 29th sees a short-period pulse—10 ft from the SW at 10 seconds, but cross-shore wind at 15 mph creates a chop. Better for kite gear.

Sunday the 30th cleans up again: 7 ft to 7 ft SW at 12 seconds, clean.

Monday the 31st morning has offshore wind and a clean 7 ft SSW swell.

And Tuesday the 1st of September morning finishes strong: 10 ft from the SW at 14 seconds, clean, with strong energy (2857).

Your true standouts: Thursday the 20th morning for raw power, and Tuesday the 25th afternoon for that exceptional long-period groundswell under glass. Both are expert-only. For smaller, cleaner sessions, look at Saturday the 22nd morning or Thursday the 27th afternoon.

Water temp is about average for the time of year, no major anomaly, so a 3/2 wetsuit should be fine.

Rusty, out.
