Tainohama Surf Forecast and Surf Report

G’day, Rusty here. Let’s be straight with you—what we’ve got on the cards for Tainohama over the next two weeks is a real slow burn. For the first week, it’s flat as a pancake, with barely a whisper of swell. You’re looking at a solid gap of about seven days with nothing worth paddling out for. The wind’s mostly onshore, chopping up any tiny bump that tries to form. The energy’s weak, with combined swell energy readings sitting in the 30s and 40s (33–90), just not enough to get excited about.

Then, things start to stir around Friday, July 24th. The morning brings a bit of life—a glassy surface with a 1ft swell from the SE, period at 18 seconds. That’s a long-period groundswell, which means clean lines and proper shape, but it’s tiny. Combined energy is 90, still weak. The wind is glassy, so it’s the most promising session of the early period, but you’ll be scratching for waves.

The real standout doesn’t arrive until Monday, July 27th. The morning shows a 3ft SE swell at 14 seconds, with light onshore wind and combined energy jumping to 323 (moderate). It’s still marginal, but the size is building. The following days ramp up fast. Tuesday, July 28th has a 7ft SSE swell at 12 seconds in the morning (energy 1754), and by the afternoon it’s 8ft at 13 seconds (energy 2527). That’s strong wave energy, but the wind is cross-onshore, so it’ll be choppy. This is expert territory at over 8ft.

The biggest pulse hits Wednesday, July 29th—10ft in the morning, rising to 12ft in the afternoon from the SSE, period 14 seconds, with onshore wind. Combined energy is 3678 and 4815—very strong. This is big, powerful stuff, but it’s rough. The water temperature is about average for the time of year, no anomaly flagged.

Friday, July 31st is the best call for the whole outlook. The morning brings a 16ft S swell at 15 seconds, with a gentle cross-onshore breeze and combined energy of 10788—that’s extreme. It’s a very long-period groundswell, so while it’s massive, the long period means it’ll be better organised at a reef like Tainohama, with longer lulls between sets. The wind is just a gentle breeze, so it’s not totally blown out, but it’s cross-onshore. This is strictly for experts, no question. Crowds are possible here—listed as “sometimes”—so you might have company.

Overall, if you’re after the one true standout, it’s Friday, July 31st morning at Tainohama (Japan). The swell is huge, the period is long, and the wind is manageable. It’s a proper heavy slab for the experienced crew. The first week is a write-off, so save your energy for the end of the month.

Rusty.
