The Lowdown
Alright folks, Rusty here. Let’s look at what’s on the table for Publics. There’s a lot of forecast to get through, but you’ll have to be patient because the first week and a half is pretty much a write-off for a decent paddle. We’re looking at a long, frustrating gap before any real hope shows up.
The core problem is that nasty cross-off wind from the ENE that just won’t let up. It's blowing hard, 19-31 mph, for the first few days, chopping everything up. The swell is there, but it’s messy. From Wednesday, August 12th through to Monday, August 17th, it’s a grim picture. We’ve got a solid, long-period groundswell from the S and SSE pushing moderate energy into the beach – you can see the energy readings in the 800-900 range and even blowing past 1000 on the 14th and 15th – but that wind is killing it. The water is a warm 81°, about average for this time of year.
The worst of it is the 15th and 16th of August. The swell jumps up to 12 ft to 13 ft from the E and ENE, with combined energy readings of 1829 and 2563 – that’s strong to very strong stuff. But it’s accompanied by a near-gale force wind at 31 mph. That’s not a surfing setup, that’s a kite-surfing dream. For a beginner, that’s way too big, and for anyone else, the wind is just too savage.
Things don’t get any better. The pattern continues with strong cross-off winds and marginal conditions. The swell period drops to a short, weak 7-8 seconds on the 18th and 19th, with energy falling to the 300-400 range. We get a few glimpses of cleaner, longer-period S and SSW swells from the 19th onward (periods of 14-18 seconds), but the wind is still a cross-off breeze, and the wave heights are small, mostly 2 ft to 4 ft. The forecast scores are consistently low, rating it “poor” or “marginal” right through to the 27th of August. There’s just no window where the wind and swell line up for a clean, rideable wave.
The best bet on offer? It’s a thin one. Look at the morning of Thursday, August 25th. The swell is 4 ft from the SSW, with a period of 16 seconds. That’s a proper long-period groundswell. The wind is ENE at 19 mph, so it’s still cross-off, but the energy is up to 779 – a moderate pulse. It’s far from perfect, but it’s the most promising thing in this whole 16-day window. The swell direction is a match for the optimum direction for this spot, and the long period will give the waves some shape. Don’t expect a classic day, but it might be the only one worth a look. The morning of the 25th is the standout.
So, the honest truth is, if you’re looking for a good surf at Publics, this forecast is a bust for the first week and a half. From the 12th to the 24th, it’s a long stretch of poor to marginal conditions. The only real hope is that window around the 25th, but even then, it’s a gamble. The crowds will be there, as always, but I doubt there’ll be much competition for waves.
Stay patient, and keep an eye on the charts. Things can change, but right now, it’s a tough call.
Rusty.

Information about the Publics Surf forecast
The above surf forecast table for Publics provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Publics can be found by selecting the local surf guide option on the grey menu. Our Publics 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 (Publics) 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 Publics 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.
Publics is 6 km (4 miles) from Honolulu. If you plan a vacation in Oahu, look for hotels and other accommodation in Honolulu. Honolulu has rooms for a wide range of budgets as well as car hire and transport links.
