Alright folks, Rusty here. Let’s talk about what’s coming up at Tainohama.
We’ve got a real mixed bag ahead. The standout is undeniably this Sunday morning – the 12th – and it’s for the experienced crew only. We’re looking at a solid 10ft SSW swell, that’s proper groundswell territory with a 16-second period, packing some serious energy (4895). The water’s a bit colder than usual for this time of year at 77°, about 3° off the norm. But the real magic? Glassy conditions with zero wind. For a south-facing reef, that’s as good as it gets. It’s a big, powerful wave, so if you’re not dialled in and confident, give it a miss. The afternoon on Sunday stays clean with glassy wind and a dropping 8ft SSW swell.
Monday the 13th still has some decent size, with 5ft SSW swell in the morning and glassy conditions, but the energy is dropping off (707). By the afternoon, it gets a bit onshore and messy.
Tuesday the 14th drops right down to 3ft, cross-off winds keep it clean, but it’s small, and the energy is weak (247). Wednesday the 15th is tiny, 2ft, and pretty ordinary. Thursday the 16th and Friday the 17th are flat and poor – a real lull.
Then, a glimmer of hope for Saturday the 18th. We get a pulse of 4ft ESE groundswell (787) with a very long 15-second period and glassy conditions in the morning. This is a long-period groundswell, so at a beachbreak like Tainohama it can be a bit straight, but it’s clean and there’s energy. The afternoon picks up to 6ft but gets a bit of cross-on breeze.
Sunday the 19th is a bit of a washout with a bumpy 8ft ESE swell turning onshore and messy. Monday the 20th is small and chopped. Tuesday the 21st offers a clean 4ft ESE swell in the morning with glassy conditions – nice for the small-wave gear.
Wednesday the 22nd is worth a look, with 5ft ESE groundswell (840) and a 13-second period under glassy skies. That’s a clean, fun option for a mid-week session.
From Thursday the 23rd through to the start of the next week, it’s mostly poor, onshore, and small. There’s a small window on Saturday the 25th with a 4ft SSE swell in the morning, but it’s onshore. Sunday the 26th is similar, onshore and average. The run to the end of the outlook is weak and choppy.
So, to be blunt: if you’re an experienced surfer, get out there Sunday morning the 12th for the best, cleanest, most powerful swell of the window. Otherwise, look at Saturday morning the 18th or Wednesday morning the 22nd for clean, smaller options.
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.
