The Lowdown
Alright, grab your board and let’s see what’s cooking for Pohoiki. It’s gonna be a long wait, but there’s a pulse in the deep forecast.
Honestly, for the next week and a half, it’s pretty grim. We’ve got a gap that stretches from now until around the start of the second week. Lots of crummy, onshore winds and messy waves. The water temp is sitting at a warm 81°F with a 1°F anomaly, so pretty average for this time of year—nothing wild there.
Things start to get interesting around Friday, August 14th. The swell picks up to a solid 8 ft out of the East, with a period of 12 seconds. The wind goes cross-off, which means cleaner conditions. The wave energy is pumping hard with values hitting 2146 to 2675. This isn’t for beginners though—over 8 ft is expert territory. Pohoiki is a reef break so it can handle that size, and it’s fairly consistent, but crowds are *sometimes* a thing here.
Now, the real standout—and I mean a proper standout—is Saturday, August 15th. This is the one you circle on your calendar. We’re looking at a massive 18 ft to 20 ft swell, direction East-Northeast, period still a meaty 12 seconds. The wave energy is off the charts, shooting up to 15938 to 18625. That is serious, serious power. The morning has offshore wind from the WNW at 16 mph, making for glassy, clean conditions. But listen—this is way too big for anyone except the most experienced chargers. At that size, even a reef like Pohoiki is only for the brave. The afternoon swings around to a cross-on wind, so the early session is the window.
After that beauty, it drops back into the usual onshore slop for the rest of the 16-day run. Winds stay cross-on and choppy, and the waves are small or junky. Not worth paddling out.
So, in a nutshell: sit tight through the first half of August. The real action hits on Friday the 14th and peaks Saturday the 15th. That Saturday morning is the best on offer—just know your limits.

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.
