The Lowdown
Right, mate, Rusty here. Let’s have a look at what’s on the cards for Tainohama.
Straight up, the first few days are a bit of a write-off. We’ve got some swell around, but the wind and rain are making a mess of things. The first real sniff of something decent comes on Saturday the 5th, but it’s not until Sunday the 6th that things start to get interesting.
Thursday the 3rd is a no-go with a risk of thunderstorms. Friday the 4th is heavy rain and messy.
Saturday the 5th afternoon sees a window of opportunity. Tainohama picks up a 3ft swell from the ESE with a period of 8 seconds and a gentle offshore wind. The combined energy is moderate at 399. It’s clean, but it’s not a world-beater.
The standout of the first week is Sunday the 6th. We’ve got a 8ft swell from the ESE on the morning, dropping to 8ft in the afternoon. The period is short at 8 seconds, but combined energy is strong at 805. With a light to gentle cross-offshore breeze from the NNE, it’ll be clean and punchy. This is a solid session for experienced surfers, as the size is pushing into expert territory.
Monday the 7th is still good with a 6ft to 7ft swell, but the wind gets a bit tricky in the afternoon. Tuesday the 8th is blown out with a strong onshore wind and a 10ft swell – that’s kite-surfing weather, not for a paddle.
The real big-ticket item is Wednesday the 9th. The swell is a solid 10ft from the SE, with a long period of 11 seconds, giving it a combined energy of 2164 – that’s very strong. Paired with a light cross-offshore breeze from the NNE in the morning, the conditions are excellent for experienced surfers only. This is heavy, powerful groundswell, and at over 8ft, it’s not for the faint-hearted.
The following week is quieter. Thursday the 10th has a 6ft to 6ft swell with a moderate offshore wind, but it’s not as clean. Friday the 11th is small and ordinary. Saturday the 12th morning has a brief moment of glassy conditions with a 4ft swell, but it’s tiny. Sunday the 13th is similar with small, clean 3ft waves.
After that, there’s a real low point from Monday the 14th through Wednesday the 16th, with poor conditions and small, weak swell. It’s a bit of a dead zone.
But hold on, because the end of the 16-day window brings a promising long-range call. On Thursday the 17th afternoon, we see a 5ft swell from the SE with a very long period of 14 seconds and a combined energy of 1510. That’s a lovely groundswell, and with a gentle offshore from the NNW, it’s going to be clean and lined up. The next day, Friday the 18th morning, is even better: a 7ft swell from the SE with a 12-second period and a combined energy of 1911. The offshore wind is reinforcing, making for excellent conditions for those who know what they’re doing. It’s a long way out, so don’t book the ferry yet, but it’s a nice one to have on the radar.
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.
