The Lowdown
Alright, Rusty here with the forecast. Let's be honest, the first week is a bit of a grind, but there are a couple of windows to get wet.
The best option on the table is Suicide Cliffs. It's a very consistent reef break that's open to the SW swell it likes, so it's always got something. The water is 85°, which is right where it should be for this time of year.
The first real chance comes on Thursday morning, August 13th. It's not huge, around 4ft of SW swell, but the wind is from the NW at 15 mph, which is cross-offshore. That'll keep it clean. The wave energy is moderate (339). There's a risk of thunderstorms, but the conditions are clean.
Friday, August 14th, is the standout of the first week. The morning sees a bit more size at 5ft from the SSW, with a light NW cross-offshore breeze (6 mph). The energy is still moderate (272), but it's clean. The afternoon gets even better – the wind turns to a light offshore from the NNW (9 mph), polishing the 4ft SW swell. That's a proper session.
After that, the weekend gets messy. The wind swings onshore from the east, and the quality drops off a cliff. We hit a dry spell from Saturday, August 16th, all the way through the end of the week.
Now, for the second week. On Tuesday, August 25th, we get a massive pulse of swell. The numbers are huge – 10ft to 12ft of SE swell, with a 14-second period. That's a long-period groundswell packing a ton of energy (3970 to 4762). The wind is light and onshore from the south, which isn't perfect, but the tide might make it work. This is for experts only, 12ft is serious. The next day, Wednesday the 26th, it gets even bigger. 16ft of S swell with a 15-second period. That's an insane amount of energy (10302), but the wind is a messy cross-onshore from the SSW. That's a big, lumpy, dangerous ocean. Only for the most experienced, and even then, it's a wild one.
So, to wrap it up: Friday, August 14th is your best bet for a clean, fun wave. The following Tuesday, August 25th, is where the size is, but it's a completely different beast. Keep an eye on that wind.
Rusty.

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

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.
