The Lowdown
Alright, let’s get into it. Look, I’ll be straight with you – the next week and a half is a tough watch. We’ve got a long stretch of messy, blown-out conditions with strong onshore winds and building storm swell that’s just not gonna be safe or fun for anyone. A few spots in the second week show some promise as the wind and swell relax, but it’s a real patience game.
The standout window is the first few days of September. The 1st through the 5th is where we see the most potential. The water temperature at Suicide Cliffs is sitting right around the long-term average for this time of year, so no surprises there.
The first real hope comes on Tuesday morning, 1st September. Suicide Cliffs will see a 5ft SSW swell with a clean cross-offshore breeze from the NE at 15 mph. The swell energy is moderate (825), and the direction is off the optimum SW, but the wind should keep it tidy. Tuesday afternoon drops a little to 4ft but the period stretches to 12 seconds, giving it a bit more shape. Expect smaller crowds.
Then Wednesday, 2nd September, is shaping up nicely. Morning and afternoon both have offshore winds from the NNE to N at 12 mph, with a 4ft SW swell at 11 seconds. The energy is moderate (457), and the wind is solid offshore – that’s clean surf. This is one of the better windows across the whole forecast.
Thursday the 3rd continues the trend with a gentle offshore breeze in the morning, 4ft SW swell at 10 seconds, and mild energy (296). The afternoon stays clean but the wind swings cross-offshore. Still good.
Friday the 4th is another strong contender. Both morning and afternoon have offshore winds from the north at 16 mph, with 4ft SW swell at 9 seconds. The swell energy is lower (216), but the wind is clean and consistent. This is a classic, user-friendly session.
Now, before that – the gap from now through to the end of August is rough. From Thursday 20th right through to Sunday 30th, the swell is either too big, blown out, or just messy. The energy numbers are huge at times – over 3600 on the 22nd – but the wind is near gale force onshore, the period is short, and the conditions are poor. This is big, dangerous, junky surf. Suited more for kite surfers than paddle surfers, honestly. The 25th and 26th flip to cleaner winds, but the swell is small and the energy is low (100-500 range). You might get a few marginal waves, but nothing to get excited about.
So, bottom line: wait out the stormy stuff. The real action is the clean, offshore mornings from 1st to 5th September at Suicide Cliffs. That’s your window.

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. If you surf the same spot (Suicide Cliffs) 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 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.
