Tainohama Surf Forecast and Surf Report

Alright, Rusty here, and I’ve got the lowdown on what’s cooking at Tainohama for the next couple of weeks.

First off, we’re in for a bit of a slow start, I won’t lie. The water’s sitting at 84°, which is a touch warmer than normal for this time of year, so boardshorts are the go. But the surf? It’s pretty ordinary for the first few days. Thursday the 27th is a write-off with choppy cross-onshore winds, so don’t bother paddling out. Friday the 28th through Sunday the 30th offers small, clean waves in the mornings – glassy conditions with a few ankle-to-knee high runners around 3 ft – but the energy is weak (107 to 166 combined energy). It’s a nice paddle more than a proper surf.

Monday the 31st has a bit more push with a 4 ft swell from the SSE, but the wind is onshore, so it’s messy. Then Tuesday the 1st of September through Thursday the 3rd gets a bit of a bump in size (5 ft to 8 ft), but the wind cranks up from the SE, making it choppy and poor. The energy is moderate to strong (493 to 976 combined energy), but the onshore wind just ruins the surface. This stretch is a hard pass.

Now, here’s where it gets interesting. Friday the 4th of September is the real standout. Morning kicks off with a clean 7 ft swell from the SE, glassy as a mirror, and the energy is pumping (1203 combined energy). This is proper expert territory – too big for beginners – but for the experienced crew, it’s going to be firing. The afternoon gets even bigger, hitting 10 ft with a moderate offshore wind from the NNW, keeping it clean. This is the best of the best on offer.

Saturday the 5th and Sunday the 6th keep the size up (7 ft to 10 ft) with clean conditions and cross-offshore winds. The energy is strong (1125 to 1489). This is still excellent for experts, but the crowd will be there – Tainohama is "sometimes" busy, so expect company.

Monday the 7th drops back to 3 ft with glassy conditions in the morning – a nice recovery session. Then Tuesday the 8th brings a solid 5 ft swell from the south with a clean offshore breeze, and the energy is decent (612). Not a standout, but a good day.

Looking further ahead, Wednesday the 9th of September is a monster morning. You’ve got a 8 ft swell from the south, glassy calm, and a very long period of 14 seconds. The energy is extreme (2708 combined energy). This is a very long-period groundswell, and at a reef break like Tainohama, it’s going to be a special session for experts. The afternoon gets even bigger (13 ft) but gets a bit choppy with cross-onshore wind. The 11th of September also looks massive (13 ft) with a clean offshore flow, but that’s a full week away, so keep an eye on it.

For the whole run, the best options are the morning sessions on the 4th and the 9th. The 4th is the cleaner, more reliable call for experts. The 9th is a promise of something truly special, but it’s a long way out, so don’t book the day off just yet.

Rusty.
