The Lowdown
Alright, Rusty here again for the imperial version. Wailua/Horners – an advanced reef that’s inconsistent and often packed. The next 16 days? Rough. From now up to July 26, every day’s a bust: onshore winds out of the east-northeast at 12–15 mph, sloppy small swell with short periods. Even when a 16-second groundswell from the west rolls through on July 14–15 at about 2 ft, the wind kills it. Water temp is 79°F – right on average. But the surf? Poor all the way.
Then July 27–28 finally shows a pulse. Monday the 27th: 4 ft easterly swell, 15-second period, light east wind but cross-onshore. Combined energy 1042 – moderate. Only marginal. Tuesday morning July 28 is the best of the bunch: 6 ft from the northeast, 9-second period, wind light easterly at 6 mph, cross-shore. Combined energy 1156. That’s the cleanest window, but still not great – just a notch above marginal. For an advanced surfer, it might be worth a paddle. But the spot is inconsistent and often crowded, so don’t expect a party.
That’s your lot. The rest of the stretch is a ghost town.

Information about the Wailua/Horners Surf forecast
The above surf forecast table for Wailua/Horners provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Wailua/Horners can be found by selecting the local surf guide option on the grey menu. Our Wailua/Horners 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 (Wailua/Horners) 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 Wailua/Horners 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.
