The Lowdown
Alright folks, Rusty here. Let's have a proper look at what's coming our way for Publics.
Right off the bat, I gotta be straight with you – the next week and a half is a bit of a write-off. We've got a long stretch of nothing special on the cards. The surf is there, but the conditions are just not playing ball. The winds are stuck in a cross-off pattern from the east-northeast, which isn't terrible for shape, but the real killer is that the swell is mixed up with short-period wind chop for days on end. The wave energy is moderate, but it's all over the place, and the scores are low. You're looking at a lot of small, weak stuff or junky, blown-out lines. For the first few days up to September 17th, we're talking small swell around 2ft to 3ft from the southwest, with long periods of 18-19 seconds. That's a groundswell, which is good for points and reefs, but at a beach setup like Publics, it can break a bit too straight and be inconsistent. The water temp is sitting at 81° with a normal anomaly, so it's about what you'd expect for this time of year.
Then things get a bit bigger, but not better. From the 17th through the 22nd, we see the swell jump up to 6ft to 8ft, but it's all coming from the east-northeast with a terrible period of 7 to 9 seconds – that's pure windswell, and it's going to be messy. The winds are fresh and strong, 18 to 25 mph, which will just rip the face off anything that tries to stand up. The energy is high, with values hitting into the 1000s, but it's ugly energy. Honestly, for a few of those days, the setup looks more interesting for kite surfing than paddle surfing unless you're a glutton for punishment.
The standout window, and I mean the only real one, is shaping up for Wednesday, September 23rd. This is the one to circle on your calendar. The forecast shows the swell holding at a solid 8ft from the east, with a period of 9 seconds – a big improvement. But the real magic is the wind. It's swinging around to the northeast and dropping to a gentle 9 mph, and it's forecast as *offshore*. That means clean, groomed faces. The wave energy is very strong at 1171, and the score for that afternoon is the highest of the entire run. For an exposed beach and reef break that's always crowded, getting a window of nearly glassy offshore wind is a rare gift. This is the pick of the bunch for experienced surfers, as 8ft is pushing it for beginners. Get on it if you can.
After that, the 24th turns ugly again with onshore winds and thunderstorms, and the rest of the run into the end of September and start of October fades back into small, poor-quality swell with relentless strong winds. There's nothing else worth mentioning.
So, to sum it up: endure the junk for the next week, and make the most of Wednesday, September 23rd. That's your shot.
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.
