Tainohama Surf Forecast and Surf Report

Alright, this is Rusty checkin' in from the Tainohama region. The water temp is sittin' right around 83°F—pretty much spot on for this time of year, so no surprises there.

The outlook starts off a bit flat. Friday the 21st and Saturday the 22nd are just small and messy, with poor surf and choppy conditions. Sunday the 23rd is even smaller, barely a ripple. You’re not missin’ anything those first few days.

Monday the 24th of August sees a jump in swell, with a 5ft SE swell (19 sec period) in the morning. The energy is moderate (175), but the conditions are marginal. The afternoon gets bigger at 8ft from the SE, but the period drops to 16 sec and the onshore wind keeps it from being clean. Still, this is the first sign of life.

Now, Tuesday the 25th of August—that’s the standout. The morning is glassy with a solid 13ft SSE swell, period of 16 sec, and an incredible combined energy of 8733. This is big, powerful, expert-only surf. The swell direction (SSE) lines up nicely with the optimum S direction for the break. The afternoon gets a bit bigger at 15ft, but the wind swings onshore, making it less user-friendly. If you’re a seasoned charger, the Tuesday morning glass-off is your window.

Wednesday the 26th and Thursday the 27th are a write-off with strong cross-onshore winds and stormy conditions, despite the big swell. You don’t wanna be out there.

Friday the 28th of August morning brings a drop in size to 8ft SSE, but the wind is glassy again. The energy is moderate (820) and the conditions are good, though the risk of thunderstorms hangs around. The afternoon turns cross-onshore and less appealing.

The weekend of the 29th and 30th of August is small again, with waist-high, short-period swell. The Saturday morning is glassy with a 4ft SE swell, but it’s weak (269 energy). Just a dribbler for a longboard or a fish.

The start of the new week (31st August to 2nd September) is poor, with small, messy surf and increasing onshore winds. Not worth paddlin’ out.

Then, on Thursday the 3rd of September, the second standout appears. The morning is glassy with a 8ft ESE swell, but the period is a massive 20 sec—very long period groundswell. The energy is through the roof at 5979. This is an expert-only day, and the long period will make the waves pour over fast at Tainohama, which is a reef. The afternoon sees a bigger 12ft E swell (19 sec period, 9420 energy), but the wind turns onshore again.

Friday the 4th of September drops down to 5ft E swell (13 sec period, 821 energy) with onshore wind—marginal at best. The rest of the run into the 5th of September is small and messy.

So, to sum it up: the best of the best is the Tuesday the 25th of August morning for the big, glassy, expert-level SSE groundswell. The second standout is the Thursday the 3rd of September morning, also glassy, with a massive 20-second period ESE swell for the experts. Both are for the skilled crew only.

Rusty out.
