The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking at the Hawai River.
Right now, things are pretty flat and ugly. That first bit of the forecast – Sunday the 9th of August – is a total write-off: rain, bumpy onshore wind, and a messy 6ft swell with a short, weak period. Not worth getting wet for. In fact, the whole first week is a struggle. We’ve got a Monday morning on the 10th that throws up 7ft swell (671 energy), but the wind is cross-off and the quality just isn’t there to back it up. A few glassy mornings pop up on the 11th and 12th, but with tiny 3ft to 3ft swells and weak energy (163 down to 110), it’s more of a paddle-around session than anything with grunt. From the 13th through the 22nd, we’re looking at a long, drawn-out dry spell – mostly below 3ft, often under 2ft, with combined swell energy dropping into the double digits and even single digits. There’s a lot of clean-looking glassy conditions in there, but no swell to back it up. That’s a tough stretch.
The real standout shows up way down the line, on Monday the 24th of August. That’s when the Hawai River point wakes up proper. Monday morning brings a solid 5ft swell from the NNE, with a period of 11 seconds and a moderate 415 combined energy – that’s groundswell, clean lines. Wind is cross-off from the east at 15 km/h, so it should be clean and running. By the afternoon, it bumps up to 6ft with a whopping 817 energy – that’s the best energy reading in the whole 16 days. Same direction, similar wind, and the conditions are flagged as very good. The optimum direction for this break is N, so this NNE swell is right in the sweet spot. That afternoon session on the 24th is the one to circle. It’s a point break, so a longer period groundswell like this is going to wrap in nicely, with proper shaped waves and long walls. The crowd factor says “sometimes” busy, so you might have company, but for that kind of quality, it’s worth it.
Heads up: the 24th is more than a week out, so treat it as promising but not locked in. The week before is mostly a blank run, so don’t bank on anything until that last Monday rolls around.
Stay safe, stay stoked.

Information about the Hawai River Surf forecast
The above surf forecast table for Hawai River provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Hawai River can be found by selecting the local surf guide option on the grey menu. Our Hawai River 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 (Hawai River) 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 Hawai River 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.
Hawai River is 48 km (30 miles) from Whakatane. If you plan a holiday in East Cape, look for hotels and other accommodation in Whakatane. Whakatane has rooms for a wide range of budgets as well as car hire and transport links.
