The Lowdown

Alright, let’s break down what’s happening at Publics for the next couple of weeks. It’s a bit of a mixed bag, but there are a couple of windows worth paddling for.

Starting off, we’ve got small, rideable swell from the SW on Tuesday and Wednesday, around 2 ft to 3 ft, with a nice long period of 18-19 seconds – that’s real groundswell. The cross-off wind from the ENE (12-16 mph) keeps it clean, with moderate combined swell energy (485-672). Water temp is about normal for the season, no big anomaly.

Then things get chunky from Thursday, 17 September, into the weekend. Swell jumps to 7 ft to 7 ft, but it’s short-period ENE windswell (7-9 seconds) with fresh cross-off breezes. Energy climbs into the strong range (850-1193), but the quality is poor. Over 7 ft, this is expert territory, and with that short period, it’s going to be a messy, bumpy ride. Honestly, with that wind, this looks more like a kiteboarding session than a surf.

We hit a dry spell from Sunday, 20 September, through Tuesday, 22 September. Swell holds around 6 ft to 7 ft, but it’s all short-period junk with strong cross-off winds (25-28 mph). Energy is still moderate to strong, but the surf quality is poor. About three days of nothing worth chasing.

Now, the one to circle on your calendar: Wednesday, 23 September. A solid pulse of E swell hits 7 ft to 7 ft, with the period stretching to 9-10 seconds. Combined energy spikes to 1510 – that’s strong. Wind is cross-off from the ENE at 22-25 mph, so it’ll be clean but windy. This one’s only for experienced surfers at that size. The swell direction is a bit east of the ideal SSE, but with that much power, it could still offer some heavy, fast waves. Promising, but keep it in perspective that far out.

After that, we fade back to small, inconsistent SSW groundswell from Friday, 25 September, into the end of the month. Most days see 2 ft to 3 ft with 15-16 second periods, with cross-off winds. The real gem is Monday, 28 September afternoon, when we get a brief offshore wind from the NE. Swell is tiny at 2 ft from the SSW, but with an 18-second period and light offshore breeze, that’s clean, glassy fun for the longboard. Energy is moderate (722). Another standout is Wednesday, 30 September morning – offshore NNE wind at just 9 mph, with 2 ft SSW swell and a 15-second period. Energy is lower (293), but it’s going to be dead calm. For small-wave days, that’s the best you’ll get.

So, the best bets: the big E swell on 23 September for the experts, and those two tiny offshore windows on 28 and 30 September for the longboard crew. Crowds are always a guarantee at Publics, so expect company.

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.
