Tainohama Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it.

First off, I gotta be straight with you – the next week is a total washout. We’re looking at a big gap of poor conditions from Monday the 17th right through to the morning of Friday the 21st at Tainohama. Small, weak, onshore wind slop. The combined swell energy is nothing to get excited about, mostly sitting well under 100 (81) on the Monday, and it just doesn't get any better. The wind is on it or cross-onshore, and the water temp is a warm 83°F, which is about average for this time of year. Don't bother paddling out.

Then, Friday the 21st morning shows a tiny flicker of life. Swell pushes up to 4ft from the south with a period of 11 seconds, and the energy jumps to 472 (moderate). The wind is still on it, though, so it’s a marginal call at best. The afternoon stays messy.

Saturday the 22nd and Sunday the 23rd are still a no-go. That south wind has a bit of chop on it, and the swell is only around the 3ft to 4ft mark. The water's still warm, but it’s ugly out there.

Now, hold on to your board. Monday the 24th of August we get a shift. The wind swings to the northeast, light at 3 mph, blowing cross-offshore. The swell is 5ft from the SSW, but the period is short at 7 seconds. The energy is moderate (343). It’s clean, but the lack of period means it won't be world-class. Worth a look if you're desperate.

But the real standout – the one you’ve been waiting for – is the window from Tuesday the 25th of August through to Thursday the 27th. This is the pick of the forecast.

Tuesday the 25th morning, we get a serious upgrade. A 4ft swell from the SE with a long period of 14 seconds, and the energy is solid (617). The wind is a light northerly at 9 mph, cross-offshore, keeping it clean. This is a proper groundswell. The afternoon is similar, with a 13-second period. The water is still warm.

Then Wednesday the 26th, it gets proper. The swell jumps to 5ft from the SE, the period stretches to 15 seconds, and the energy rockets to 1922. The wind is a tiny 3 mph out of the northeast, cross-offshore. The morning is clean, and the afternoon goes glassy. This is excellent surf. The only catch – it’s pushing 5ft, which is getting a bit hefty for beginners, but it’s a dream for anyone with experience.

Thursday the 27th morning is the big one. 10ft from the SE with a 17-second period. The energy is a massive 5103. The wind is a moderate 16 mph offshore from the north. This is expert territory. The waves will be thick, powerful, and long-period. This is not a day for a foamie. The afternoon is cross-offshore and still clean, but the size is the same.

The long-range stuff from Friday the 28th onwards is enormous, but it’s a two-week plus call, so take it with a grain of salt. We’re looking at 13ft to 16ft swells with massive energy. Friday the 28th afternoon has 13ft from the SE with a 16-second period, and a fresh 19 mph offshore wind (8617 energy). Saturday the 29th morning is glassy with a 16ft SE swell (11713 energy). This is only for the brave. The wind shifts onshore later.

Into the first week of September, the swell drops back but stays solid. Monday the 31st of August morning is glassy with 8ft from the south (13-second period, 3160 energy). Tuesday the 1st of September morning has 7ft from the SSW with a 14-second period, light cross-offshore wind, and clean. Still excellent for experienced surfers.

So, the bottom line: skip the first week. The best windows are Tuesday 25th to Thursday 27th August for that clean, long-period SE groundswell. The absolute standout is Thursday the 27th morning for the experts, but Wednesday the 26th afternoon is pure glass and a solid 8ft. If you’re a beginner, stick to the Tuesday 25th when it’s smaller and clean.

Rusty.
