Alright folks, Rusty here. Let’s get into it.
We’ve got a classic case of a big, hefty pulse of swell coming through this weekend, but it’s bringing a lot of baggage with it. The real prize for clean conditions is a little further off. Let’s break it down.
It all starts on Saturday the 11th of July. There's a massive 13-foot swell from the south hammering away, with huge wave energy (8486). Problem is, the wind is all wrong. Saturday morning has that southerly onshore breeze, and by the afternoon it’s a cross-onshore, making things messy. This is a serious swell – definitely for experts only, and even then, it’s going to be a battle.
The real standout, the one you’ve been waiting for, is Sunday the 12th of July, in the morning at Tainohama (reef break) . It’s still a solid 12 feet from the south-southwest, but the wind goes absolutely glassy. It’s a crisp, still morning with some clouds. That’s the magic ticket. The wave energy is still extremely high (5296), but the calm conditions will give you clean, powerful lines. This is the session to circle on the calendar if you’ve got the skills.
Sunday afternoon sees the swell drop to 8 feet, with an onshore wind kicking up again, so it’s less of a draw. The energy is still substantial (2771), but the wind spoils it.
Monday the 13th still has some decent, dropping swell. Morning sees a 5-foot south-southwest groundswell with a 12-second period, and it’s glassy calm. The energy is moderate (681). The tide is the variable here, so pick your bank, but it’ll be a rewarding session for those who know the spot. The afternoon is a touch smaller at 5 feet but still glassy.
The water temp is sitting at 76°F, which is a bit colder than normal for this time of year – you’ll want a spring suit unless you’re tough-skinned.
Tuesday the 14th is where it starts to get small. Clean cross-offshore winds with a 3-foot waist-to-chest high swell, but the energy is dropping (251). The rest of that week and the following week (15th July through 22nd July) is a very quiet run. Wave heights barely break 3 feet, most of the time it’s tiny and onshore. There’s a long, quiet gap here.
Now, for the second week, things look more promising but are less certain. There is a flicker of life on Wednesday the 22nd of July morning. It’s small, only 1 feet, but it’s glassy and a long-period 17-second groundswell sneaks in. The energy is moderate (229). If you have a log and a lot of patience, that’s a curious glassy window.
The real long-range promise is on Sunday the 26th of July. The morning brings a clean, 5-foot south-southwest groundswell with a cross-offshore wind and good combined energy (967). This could be a very good day with clean lines. The afternoon bumps up to a 4-foot south-southwest swell with a 15-second period but the wind swings onshore. The energy jumps to 1911, but it’s a marginal tide call. That morning of the 26th is the best bet in the second week.
Overall, if you’re looking for the one session to charge, it’s undeniably the glassy, 12-foot groundswell at Tainohama on Sunday morning, July the 12th.

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.
