The Lowdown
Alright, Rusty here. Let’s break down what Tainohama’s got for us, in feet and knots.
The first stretch is pretty flat and quiet. From July 22nd through the 29th, the surf is tiny—we’re talkin’ 1 to 2 feet at most, with energy readings that are just weak (33 to 270). There are some glassy mornings, but the waves are just too small to call it a session. Water temp is about 82°F, which is par for the course around here. This is a long, quiet period for the break.
You’ll see a little pulse on Thursday, July 30th. The morning swell comes up to about 3 feet from the SSW, with a 12-second period and moderate energy at 270. The wind goes glassy, so it’ll be clean. It’s not a classic, but it’s a start.
The real standout, the one that’ll have you setting your alarm, is Sunday, August 2nd. We’ve got a proper groundswell pushing in—6 feet from the ESE, riding a very long 18-second period. The energy is huge at 2039. Early morning the wind is dead calm, so expect glassy, clean conditions. This is excellent surf for experienced surfers only. That long period will wrap nicely into this reef setup, making for some proper waves.
Monday, August 3rd, keeps the goods coming with a 5-foot east swell and a 17-second period. Morning winds look clean from the north, with strong energy at 1357. Another great session for the rippers.
Remember, Tainohama is a reef break for advanced surfers only. It’s fairly consistent, with crowds possible, so get in early. The best wind is from the NNW.
Bottom line: don’t bother paddling out too much until Sunday the 2nd and Monday the 3rd of August. That’s your window.
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.
