The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Tainohama.
To be straight with you, the next week and a half is a bit of a write-off. We’re looking at a long, dry spell of tiny, weak swell with poor conditions. From Wednesday the 15th right through to the morning of Saturday the 26th, the best you’ll get is a few knee-high, rippled-out dribblers. The wave energy is mostly in the low double digits or triple digits, which is pretty weak. Honestly, it's not worth paddling out for.
Now, there’s a little flicker of life on the morning of Saturday the 26th. The wind will be dead calm – glassy as it gets – and we’ll see a bump of swell push in from the SW at 4ft. The period is a short 6 seconds, so it’ll be a bit fat and crumbly, but with zero wind, that reef at Tainohama might just offer a few fun, clean lefts. The combined energy is moderate (315). It’s the only real window in the first half of this outlook, but don't expect any kind of classic session.
The real standout, the one to circle on your calendar, is Thursday the 30th of July. That morning, the forecast shows a solid 7ft swell from the SE, with a very long period of 18 seconds. That’s a proper groundswell, packing a lot of punch – the energy reading is a massive 4852. The wind will be glassy, a light ENE breeze keeping the surface perfect. This is a powerful, clean swell, but it’s one for the experienced crew. At 7ft and with that long period, it’s going to be a heavy, grinding wall on the reef, and it’ll be closing out and too much for beginners. If you’ve got the skills, this is the day. Keep in mind, with a long period like that, the sets will be widely spaced, but the waves that do come through will have serious shape and power.
The water temperature is about what you'd expect for this time of year, nothing unusual to report.
So, to sum it up: a whole lot of nothing for the first week and a half, a tiny, clean window on the 26th morning, and then a proper, expert-level session on the morning of the 30th. That’s your best bet.
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.
