The Lowdown

Alright, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

Straight up, I’ll be honest with you – this is a tough stretch. We’re looking at a long, dry run with hardly anything worth paddling out for. The first real chance of a wave doesn’t show up until the 24th of August, and even then, it’s a gamble. Before that, it’s all onshore wind and messy, weak swell.

The only spot in the game is Wailua/Horners (Hawaii) , a reef break that’s best for advanced crew. It’s inconsistent and can get crowded, so if you’re thinking of heading out, expect company. The water temp is about average for this time of year, nothing unusual.

So, from now until the 23rd, it’s pretty much a write-off. The wind is hammering from the ENE and NE, mostly onshore, and the swell is small and short-period. The energy is weak to moderate, with values like 177 to 191 (low energy), and it never tops a score of zero. The swell direction is mostly from the E to ENE, with a period of 6 to 8 seconds—that’s short-period, wind swell stuff. It’ll be choppy and bumpy, not worth your time.

Now, here’s the little glimmer. On Monday afternoon, 24th August, things shift. We get a glassy wind state with a light breeze from the south, and the swell from the east at 0.9m, which is about 3 ft, with a period of 9 seconds. The combined energy bumps up to 162 (moderate). The forecast says “surfable waves but very ordinary conditions,” and it scores a 1. That’s the best we’ve got. It’s not pumping, but it’s the only window where the ocean might be rideable. The period is still short, so don’t expect much power, but at least it’s glassy.

After that, the 25th and 26th slip back into onshore wind and low energy, with the swell dropping to 1.0m (3 ft) and periods of 8 to 9 seconds, but the wind is back onshore. The 27th shows a bit more energy (330) and a 1.6m (5 ft) swell from the east with an 8-second period, but the onshore wind from the ENE at 20 km/h (12 mph) will ruin it.

So, the standout? That glassy window on the 24th of August. It’s the only one. If you’re desperate, that’s your moment. Otherwise, it’s a long wait for something better.

Rusty.

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.
