The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for Tainohama over the next couple of weeks.
Right off the bat, we've got a bit of a slow start. The first solid recommendation doesn't kick in until Wednesday morning, the 5th of August. Before that, Monday and Tuesday are pretty average – the swell is there but conditions are a mess, with onshore winds and choppy water making it a write-off.
The real standout window hits on Wednesday, the 5th of August. Wednesday morning at Tainohama is looking bloody good. The swell is pumping at 13 feet from the SE with a long 17-second period, giving it heaps of grunt (combined energy of 12450). The wind is a light, clean cross-shore from the ENE at 3 mph, which is going to keep things smooth. But the crystal clear winner is Wednesday afternoon. The swell jumps to 16 feet from the SE, still with that dreamy 17-second period, and the wind drops to a glassy 3 mph from the E – it's almost dead calm. The energy is massive (15148). This is where it's at. Just a heads up, this size is huge, over 8 feet, so it's strictly for the experts out there. The break is a reef, so it should handle this long-period groundswell beautifully, but it's not for the faint-hearted.
Thursday the 6th is still big, with 21 feet swell on offer, but the wind turns onshore in the afternoon, making it a bit of a battle. Friday the 7th holds size with 20 feet, but there's a risk of thunderstorms and a cross-shore wind that'll chop things up. The standout quality really is that Wednesday afternoon session.
After that, the surf drops off hard. The second week looks pretty flat. Saturday the 15th has a few pulses of 10 feet, but the winds are messy and the period drops, so it's not worth getting excited about. There's a long gap of poor conditions from the 16th of August onwards, with tiny, weak swell and onshore winds, so don't plan on much.
The water temperature at Tainohama is a balmy 84°F, which is a touch warmer than normal for this time of year – a nice bonus for when you're paddling out.
So, for the best of the bunch, lock in Wednesday the 5th of August, specifically the afternoon. It's a proper big-wave session for the experienced crew. Otherwise, you're waiting for a hopeful change in the forecast later in the month.
Stay salty, 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.
