The Lowdown
Alright folks, Rusty here. Let’s talk about what’s shaping up for Pohoiki. It’s a rough start, but if you can hold out, there’s a raw, powerful finish waiting.
For the first week and a half, it’s a tough go. From Friday the 21st through to around Wednesday the 28th of August, it’s mostly “poor surf conditions” with cross-onshore winds and choppy, messy water. The waves are small and the combined swell energy is weak to moderate, sitting between 264 and 986. You’d be fighting the wind, not riding the wave. Not worth the drive.
We start to see a turn on Thursday the 29th of August. Conditions clean up with cross-offshore winds, and the swell is still modest at around 4ft to 4ft from the east, but the energy is picking up into the 800s. By Sunday the 30th, we get a 6ft swell from the east-northeast with a clean cross-offshore breeze and energy hitting 1069—that’s a solid, surfable window. Water temp is about 81°F, which is average for the time of year, so you’re in spring suits or boardies.
Now for the real story. Monday the 31st of August into Tuesday the 1st of September is the big ticket. Monday morning sees a 12ft swell from the east-northeast, building to 13ft by the afternoon with a combined swell energy of 4161—that’s raw power. The wind goes north cross-offshore, keeping it clean and glassy. The period is 11 seconds, so it’s groundswell with some serious push. Pohoiki is a reef break that loves this east-northeast direction. But 13ft is big—this is expert territory only. Beginners, stay on the sand. The crowds are “sometimes,” but with a swell this size, expect a crew.
Tuesday morning is even cleaner with offshore winds from the northwest and a 10ft swell, energy at 2575. That’s your best session of the outlook, clean and heavy. It’s a long-range call, so check it again closer to the date.
After that, it fades back into smaller, messier cross-onshore slop through early September. There’s a bump on the 4th with a 6ft east-northeast swell and 1315 energy, but the wind turns cross-onshore, so it won’t be as clean.
So here’s the truth: the first week is dead. The real standout is the Monday 31st of August afternoon and Tuesday 1st of September morning for big, clean, powerful surf. The water’s warm, the wind’s offshore, and the swell is pumping. Just be ready for a heavyweight session.
Rusty.

Information about the Pohoiki Surf forecast
The above surf forecast table for Pohoiki provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Pohoiki can be found by selecting the local surf guide option on the grey menu. Our Pohoiki 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 (Pohoiki) 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 Pohoiki 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.
Pohoiki is 39 km (24 miles) from Hilo. If you plan a vacation in Big Island, look for hotels and other accommodation in Hilo. Hilo has rooms for a wide range of budgets as well as car hire and transport links.
