The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – the next couple of weeks at Publics (beach and reef) are a bit of a mixed bag, and honestly, most of it’s pretty average. We’ve got plenty of swell on the way, but the wind is the main problem for a lot of it. The water temp is sitting at 81°F, which is about ordinary for this time of year, so no surprises there.
The first real chance of anything decent is on Tuesday the 8th of September. The swell is pumping up to 15 ft from the east with a 12-second period, and the wind finally swings offshore from the NNE at 19 mph. That’s the big one – the combined energy is massive at 6480, so this is for experienced surfers only. It’s a standout, but it’s a heavy day. The Tuesday afternoon eases a bit to 12 ft from the east, still offshore from the north at 16 mph, and the energy’s still strong at 2676. That’s your best window for a solid, clean session.
Wednesday the 9th of September is also worth a look. The morning has 10 ft easterly swell with a 9-second period, light cross-shore wind, and decent energy (1508). But the real gem is the afternoon – glassy conditions with 10 ft east swell, 9-second period, and the combined energy at 1555. It’s clean, it’s solid, and it’s for experienced crew.
Before that, from the 30th of August right through to the 7th of September, it’s pretty grim. The wind is a fresh cross-offshore breeze from the ENE at 22 mph or more, making it a constant battle. The swell is there, mostly 6 ft to 12 ft from the ENE, but the period is short (7-8 seconds) and the energy is moderate to strong. The wave comment says “poor surf conditions” or “marginal” for most of that stretch. The 5th of September afternoon has a longer 13-second period and big energy (4649), but it’s with a risk of thunderstorms and cross-off wind, so it’s still messy.
After the 9th, things drop off again. The 10th through the 14th of September sees smaller swell (5 ft to 7 ft), short period, and mostly cross-on or cross-off winds. The 11th of September afternoon has a glassy moment with 7 ft east swell, but it’s only a brief window and the energy is moderate. The rest is just marginal.
So, if you’re keen, lock in Tuesday the 8th of September morning for the biggest, cleanest, most powerful surf – but it’s big and for experts only. The Wednesday the 9th of September afternoon is the other standout, with glassy conditions and solid 10 ft waves. The rest of the run is a write-off, with a long gap of poor conditions from the 30th of August up to the 7th.

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.
