The Lowdown
Alright folks, Rusty here. Let's take a look at what's on offer for Pohoiki over the next couple of weeks.
Right off the bat, it's a tough start. The first few days are looking pretty grim with onshore and cross-shore winds messing up the shape. We've got some swell, but the conditions are just poor. The water temp is sitting at 81°F which is about average for the time of year, so at least you won't be cold while you're getting frustrated.
The setup starts to get a little more interesting as we head into the first weekend. Friday afternoon the 4th of September, we see a shift. The swell is 7ft from the east with a longer period of 13 seconds, and the wind drops to a gentle breeze from the north-east, keeping it cross-shore. The combined energy is strong at 1656, so there's some power behind it. It's still marginal, but that's the first light at the end of the tunnel.
The real standout, though, is Monday the 7th of September. The morning session is looking like the pick of the entire forecast. We're seeing a solid 13ft swell from the north-east with a 12-second period, pumping a massive 4072 units of combined energy. The wind is blowing from the north-west at 12 mph, giving us a clean, cross-offshore flow. This is serious, expert-only territory at over 8ft. It's a reef break, so it'll handle that size, but it's not for the faint of heart. Expect a crowd, as it's "sometimes" busy.
After that, the swell drops back and the winds turn unfriendly again. From Tuesday the 8th onwards, we're back into a pattern of onshore and cross-onshore winds with short-period, choppy swell. The whole second week looks mostly poor, with a few marginal moments but nothing that really stands out. The waves are short-period and messy, making for a tough paddle.
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.
