The Lowdown

G’day, it’s Rusty here. Let’s have a look at what’s on offer for Publics over the next couple of weeks.

Right off the bat, things are pretty quiet. The first few days are a tough watch – Saturday the 18th through to the end of the week are mostly a write-off. The swell is up and down, but the wind is stuck cross-off from the ENE, strong enough to mess things up, and the wave quality is poor. You’re looking at short-period, wind-affected slop with combined energy that’s moderate at best – around 604 (July 18th morning) to 988 (July 23rd afternoon). It’s not really surfable, so you’d be better off waiting.

The gap in good surf runs from now until late July. That’s a solid week of near-nothing. Then, from Monday the 27th, things start to build. The swell picks up from the E with periods pushing 15–16 seconds, which is proper groundswell, and the combined energy climbs into the strong range – 1799 (July 27th morning) to 2055 (July 27th afternoon). The waves are around 6 ft to 6 ft, but the wind is still cross-off from the ENE, which keeps it from being truly clean. It’s marginal, but there’s potential for the more experienced crew.

The real standout, though, is Wednesday the 29th. That’s the one. The swell really fires up – 15 ft to 18 ft from the ENE with a period of 14 seconds, and the combined energy goes through the roof: 8514 on the morning and a massive 11067 in the afternoon. That’s very strong wave energy. The wind on Wednesday afternoon shifts to offshore from the NE, which is a game-changer – it’ll be clean and lined up. This is expert-only territory, obviously – over 8 ft is a big, heavy wave. Publics is a beach and reef setup, so at that size, it’ll be powerful and demanding. Crowds are always present here, so expect company. The water temperature is 80°F with a 0.5°F anomaly – that’s about average for the time of year, so no surprises there.

Thursday the 30th still holds good size – 12 ft on the morning, dropping to 8 ft by the afternoon, with light cross-off winds from the ENE and E. That’s excellent for experienced surfers, but the swell direction is ENE, and the optimum swell for Publics is SSE, so it’s not a perfect match. Still, at 12 ft with a 11-second period, it’s very surfable for the right crew.

Friday the 31st and Saturday the 1st of August fade back to 6 ft–7 ft with short period (8 seconds) and cross-off winds, so it’s back to mediocre. The combined energy drops to moderate – 759 to 792. By Sunday the 2nd of August, it’s all gone – 4 ft to 4 ft, weak energy (264 to 299), and poor conditions.

So, the best on offer is Wednesday the 29th of July – that afternoon session with offshore wind and massive swell is the one to circle. Thursday the 30th morning is also a solid option for the experienced. Everything else is either too small, too windy, or too raw. The long-range stuff looks promising but less certain – keep an eye on it.

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.
