The Lowdown
Hey, Rusty here again.
Gonna be honest, the start of this forecast is not good. Through July 17-19, the waves are poor. The public break is catching some east-northeast windswell, but it’s short-period and messy. Swell heights are around 2 to 6 ft, but the period is only 6-8 seconds – meaning weak, lumpy surf. There’s also a little bit of long-period south-southwest groundswell, but it’s less than 2 ft. The combined wave energy stays moderate, in the 300-600 range. Cross-off wind from the east-northeast keeps the surface clean, but there’s just not enough quality wave to get excited about.
Monday, July 20, is the start of a slow shift to marginal conditions. Still not good, but the ocean starts offering a little more. The best part of this period is still a full week away.
The first real standout starts on the morning of Sunday, July 26. The east swell picks up to around 4 ft with a 17-second period – classic groundswell. The combined energy jumps to strong, over 2000. That means power. The wind stays cross-off, not offshore, but still clean enough to make the waves look good.
Then the best day looks to be Tuesday, July 28. Swell hits around 7 ft from the east, period 14 seconds. The combined wave energy is over 2100 – very strong. The wind eases in the morning to a gentle breeze, which will help with surface texture. But keep in mind – the break is always crowded, so you won't be alone. Size makes this one for experienced surfers only.
Through July 29-31, the surf slowly drops but stays rideable, with 5 to 6 ft waves early in the window, then down to 4 ft by the end of the month. Cross-off wind, moderate breeze strength, still okay. Worth a paddle if you missed the peak.
By August 1, it drops right off again – not worth the effort.
So, mark your calendar for July 26 through July 29. Tuesday July 28 looks like the biggest, cleanest day overall.
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.
