The Lowdown
Pohoiki (Big Island) – the only spot on the map, and it’s not doing us any favors. The water’s sitting at 27°, which is about average for this time of year, so at least the bath’s warm.
Sunday the 13th afternoon kicks things off with a weak knee-high pulse – 0.9m from the NNE, period around 9 seconds. Energy’s low, only 212, and there’s a cross-off wind that’ll clean it up, but it’s marginal at best. You’d be fighting for scraps.
From Monday the 14th through Tuesday the 15th, it drops to waist-high mush – 0.8m to 0.6m, short-period 8 to 11 seconds, but the wind goes cross or cross-on, so it’s chopped and messy. Not worth the drive.
Wednesday the 16th sees a bit more push – 1.2m in the morning, building to 1.5m by afternoon, with energy jumping to 378 and 448. But the period’s only 10 seconds, and the wind’s cross-off in the afternoon, so it’ll be clean-ish, though still junky. The comment flags it as poor – and I trust that.
Thursday the 17th gets real – 1.9m to 2.2m from the ENE, period 9 seconds, energy up to 581 and 711. But it’s full onshore and messy. This is where I’d start thinking about a kite rather than a board – the waves are there, but the quality is shot.
Friday the 18th through Sunday the 20th stays in the 1.8m to 2.0m range, but every session is cross-on or cross with chop. Periods drop to 8 seconds, so it’s junky, walled-up beach-break style, even though Pohoiki’s a reef. You’re getting pushed around more than you’re getting waves.
Monday the 21st and Tuesday the 22nd keep the size – 1.7m to 2.3m – and energy climbs from 539 up to 986. But it’s still cross-on with that short 9-second period. Poor conditions written all over it.
Then Wednesday the 23rd throws a bit of a tantrum – 3.0m in the morning, energy at 2040, but the period’s only 10 seconds and the wind’s cross. That’s a lot of raw power with zero finesse. The comment says marginal, and honestly, at that size with that wind, you’re looking at a washing machine. If you’re a expert charger, maybe – but I wouldn’t.
From Thursday the 24th through Sunday the 28th, it backs down gradually – 1.9m down to 1.0m – but the period never gets above 8 or 9 seconds, and the wind stays cross or cross-on the whole time. Energy drops from 608 down to 181. It’s just grind, day after day.
The one bright spot in terms of raw size is Wednesday the 23rd’s morning – 3.0m, energy 2040 – that’s strong stuff. But it’s short-period and cross-shore, so it’s going to be lumpy and walled. Not the kind of swell that lights up a reef. And with that much water moving, it’s expert-only if anything.
Honestly, there’s no standout day here. No clean groundswell, no offshore wind, no long-period juice. The only consistency is the inconsistency of quality. It’s a blank run – happens sometimes.
Keep the board in the car, but don’t get your hopes up. This stretch is about as dead as it gets.

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.
