The Lowdown

G'day, Rusty here. Well, it's a bit of a tale of two halves for Tainohama. We've got a slow start with messy, onshore winds, but hold onto your boardies because there's a massive, late-season swell brewing that will demand your full respect… if you've got the skills.

The water sits at a balmy 84°, which is a touch warmer than normal for this time of year. That extra bit of tropical warmth will be a nice bonus if you're out there.

Things kick off on Monday afternoon, but don't get too excited. We're looking at a 7ft SSE groundswell on a 16-second period, but it's blowing a cross-on 9 mph from the south. The combined energy is a hearty 2408, but the wind's wrecking the surface. Tuesday and Wednesday are more of the same – plenty of swell in the water, but the southerly winds are cross-on, making for choppy, lumpy conditions. A 10ft swell on Tuesday morning with 3906 of energy is a lot of water moving, but it's not clean.

Thursday the 28th offers a brief window of hope. Friday morning sees the wind drop out completely to glassy conditions, with a tiny 4ft S swell, 8-second period, and a weak 200 of energy. It's small and gutless, but it'll be clean. Saturday and Sunday mornings keep that glassy, clean feel, but the swell is tiny – barely 3ft – with minimal energy. It's rideable for a fun log, but nothing to write home about. Monday and Tuesday are a bit of a write-off with more onshore junk.

Now, for the real action. Thursday the 3rd of September is where things start to get serious. The wind swings around to a clean cross-off from the NNE at 12 mph. A solid 7ft S groundswell with a 14-second period rolls in, packing 2236 of energy. The water will be clean, and the reef at Tainohama will absolutely love that long period. For the experienced crew, this is a standout.

But the beast arrives Friday the 4th of September. Holy mackerel. We've got a 13ft SSE swell on a 14-second period blowing up to a massive 8103 of combined energy. The wind is still a clean cross-off from the NNE at 12 mph. This is world-class power, and Tainohama is a reef break, but this is still expert territory only. For anyone with less than elite-level skills and a death wish, give it a wide berth. Saturday the 5th is even bigger but also gets a note of caution – 23ft swell with 16368 of energy! The wind is a fresh offshore from the NNW at 22 mph, so it'll be clean, but the forecast itself says the swell is predicted to be too big for this break. It'll be a show to watch, but don't paddle out.

Sunday the 6th drops back to a still-chunky 8ft S swell with 1014 of energy and clean cross-off winds. It's much more manageable and will offer some solid, powerful waves on the reef.

Rusty.

Information about the Tainohama Surf forecast

The above surf forecast table for Tainohama provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tainohama can be found by selecting the local surf guide option on the grey menu. Our Tainohama surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Tainohama) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Tainohama may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
