The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer at Publics over the next couple of weeks.

First up, the water temp is sitting at about 80°, which is about normal for this time of year, so no surprises there.

Right off the bat, we’ve got a couple of small, clean windows. Monday afternoon the 20th of July brings a clean 3ft south swell with a very long 16-second period. That’s a proper groundswell, but it’s tiny, and the wind is a cross-off from the ENE at 19 mph. The combined energy is weak (595). It’s a marginal call, but if you’re keen, you might find a little fun one. Tuesday morning the 21st is similar, with a 3ft south swell at 14 seconds, and lighter winds at 12 mph. The energy is still weak (533). After that, things get messy. Wednesday the 22nd through to Friday the 24th is mostly a write-off with poor surf conditions, strong cross-off winds, and a messy mix of short-period windswell. The one exception is Friday afternoon the 24th, when a 7ft short-period ENE swell hits, but the wind is howling at 25 mph. That’s a whole lot of chop and not much fun for paddling – honestly, that setup looks more interesting for kite surfing.

We hit a bit of a lull until Saturday the 25th, with a small SSW swell, but the energy is starting to build (1098). Still, it’s marginal.

Now, here’s where it gets interesting. The standout window is Tuesday the 28th. Tuesday morning the 28th we see a 7ft east swell at 13 seconds, with a gentle breeze of 9 mph, and the energy is strong (1663). But Tuesday afternoon is where it’s at: a 8ft ENE swell, a gentle 9 mph offshore wind, and the energy is very strong (2184). That’s clean, offshore, and solid. This is for experienced surfers only – that size is pushing into expert territory. Wednesday the 29th carries on the vibe with a 8ft to 8ft ENE swell and light winds, but it’s a cross-off, so not quite as perfect as that Tuesday afternoon. Still, it’s a solid run.

After that, the swell drops off fast. Thursday the 30th and Friday the 31st are back to small, weak, and poor conditions. The first week of August looks like a total write-off with strong winds and onshore slop, so don't hold your breath.

Overall, the best bet is Tuesday afternoon, the 28th of July at Publics. That 8ft ENE swell with a gentle offshore wind is the call. The water is average temp, the break is always crowded, so expect company, but for the experienced crew, that’s the session.

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.
