The Lowdown
Alright, Rusty here, let's talk about what's coming up.
Right now, the ocean's pretty flat. We're looking at a long, quiet spell before things get a bit more interesting. For the first week and a half, honestly, there’s barely a ripple. Don't bother checking the charts until we get past the first week or so.
Things will finally start to pick up around Monday, August 10th. We'll see some swell, around 8 ft from the SW, but it's going to be messy, with a cross-onshore wind that's going to chop things up. It's a marginal call at best, with moderate wave energy (1922).
The real story, and the only proper standout in this whole 16-day window, is the massive pulse due around Friday, August 7th and into that weekend. Now, this is a *huge* event. We’re talking a 23 ft swell from the WSW with a period of 11 seconds rolling in. The wave energy is absolutely monstrous (11229). That’s expert territory only, and it’s going to be dangerous. On top of that, we have violent storm-force onshore winds, making it completely unsurfable. For the few days after, the swell stays big, around 13 ft from the SSW, but the wind remains onshore, keeping the surf junk. It's one of those situations where the ocean has all the power of a hurricane, but the conditions are just wrong for riding waves.
We only have one spot on the radar: Suicide Cliffs. It's an exposed reef break, intermediate-plus level, and it’s very consistent. The water temp is a touch warmer than normal for this time of year at 86°, nothing too crazy. The crowds can be a problem here, but with the surf being poor for so long, it'll be quiet.
After the big storm passes, things start to clean up from Monday, August 10th onward. The swell drops to a manageable 8 ft from the SW but with a long 11-second period. The wind is lighter, cross-onshore, so it’s still a bit choppy, but the energy is still moderate (1922). It’s not perfect, but for the patient surfer, it’s the best we get. The swell direction matches the optimum for the cliffs.
So, to sum it up: a very long flat spell, then a massive, dangerous storm that you watch from the beach, followed by a few days of improving but still slightly messy surf. The standout session is looking like Monday, August 10th and Tuesday, August 11th – not perfect, but there’ll be some cleanable waves.
Rusty.

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 Suicide Cliffs 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.
