The Lowdown
Alright, let’s switch it up to imperial for those who think in feet and miles.
The first week-plus is a total bust. From now through the end of August and into September 1st, it’s poor out there. The wind is ripping, mostly cross-onshore or onshore, and the swell is either tiny or short-period junk. Combined wave energy is weak, from 29 to 1025, and the scores are zeros across the board. Nothing to ride.
Then, on Wednesday, September 2nd, the whole picture changes. The big moment is Wednesday afternoon at Suicide Cliffs. This is a very consistent reef break. The swell hits 20ft from the NW with a 11-second period. The energy is massive at 8072. The wind is a strong breeze from the northwest, cross-offshore, keeping the waves clean. This is huge, expert-only territory – well over the 8ft mark. Not for beginners.
Thursday the 3rd keeps the momentum. The morning brings 13ft from the west at 11 seconds, with a fresh offshore wind from the NNW. The afternoon is even cleaner: 13ft from the WNW at 12 seconds, moderate offshore wind, and energy at 3895. Excellent conditions for the experienced surfer. The long period is a plus here for the reef.
Friday the 4th is still good, but the swell is easing. The morning has 8ft from the NW at 12 seconds and moderate offshore wind. Energy is still solid at 1617. It’s fine for the intermediate-plus crowd, but the size is still over 5ft, so beginners should sit it out.
After that, it’s all downhill. The weekend and the following week look like small, choppy, and blown-out. The 16-day window ends with gale-force winds and tiny waves. Your best bet is that Wednesday to Friday window, with Wednesday afternoon being the absolute standout.

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.
