The Lowdown
Alright folks, Rusty here again. Let's break down the Tainohama swell in feet and miles per hour.
The next week or so is looking pretty flat and ordinary. We've got a real dry spell through the end of July and into the first couple of days of August. The swell is tiny, under 2ft, and the wind is mostly onshore or cross-on, so it's not going to be worth paddling out for. The water temp is sitting at 84°F, which is a touch warmer than normal for this time of year, so at least a swim would be nice.
Monday the 27th offers a glimmer of hope with a glassy 1ft SE swell and a 14-second period, giving us a weak wave energy (174). It's surfable, but it's really just knee-high and very ordinary. Then it's a long gap of nothing until we get to the 3rd of August.
Now, the 3rd of August Monday morning, the energy starts to pick up. Swell jumps to 4ft from the ESE with a 15-second period. The combined energy is a moderate 786, and we've got a cross-shore wind. It's still a bit marginal, but it's a step up.
The real standout, the one you've been waiting for, is the morning of Thursday the 6th of August. The swell is a solid 15ft from the ESE with a very long 18-second period, and it's glassy. The combined energy is a massive 11301 – that's very strong. This is a serious, expert-only groundswell. The water is going to be powerful, and with that long period, it'll be best at the reef. If you're an experienced surfer, this is the window. The morning of the 5th of August is also a good call with a 10ft swell and glassy conditions, a great warm-up for the main event.
After that, things get wild. The 7th and 8th of August see it blowing up to 23ft and bigger, with winds hitting 28-34 mph. The combined energy is astronomical. That's not for surfing; that's for the big boat crowd only. The offshore wind is there, but it's a "near gale" and you wouldn't be able to paddle into it. The swell drops back down to 16ft on the 10th of August with a glassy morning, offering another chance for experienced surfers on a dropping swell.
So, to sum it up: wait out this week. The focus is squarely on the 5th, 6th, and 10th of August for the only real quality windows. The 6th of August morning is the best of the best on offer.
Rusty, signing off.

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.
