Table - best surf conditions forecast for Suicide Cliffs over the next 16 days.
Hey crew, Rusty here. Just the one break to talk about for this whole stretch, and it’s a wild one.
We’ve got a massive south-east swell hitting the coast, and this reef grabs all of it. The energy numbers are off the charts – hitting five digits at one point – but the wind is plain mean. Friday July 10th is blowing 35-40 mph easterly cross-shore, turning into a gale by the afternoon. The swell is already way too big, hitting 28-31 ft with a very long 17-18 second period. This is kite-surf territory, not paddle surfing. Saturday July 11th is even uglier: severe gale force south-easterlies, totally blown out, with waves up to 43 ft. Only for the seriously crazy.
From Sunday July 12th through Tuesday July 14th, the swell drops but so does quality – down to 11 ft on Sunday with onshore wind, then shrinking to about 4 ft with a short, weak 8-second period by Tuesday. The energy drops into the hundreds. Nothing doing.
The turnaround comes Wednesday July 15th and Thursday July 16th. We get glassy mornings and light offshore winds, but the swell is tiny – only about 3 ft from the SW with a 10-second period. The energy is below 200. It’s surfable but pretty ordinary. Still, clean as a whistle and empty.
The real standout is Friday July 17th morning. A nice little 3 ft SW swell, light north-easterly cross-offshore breeze, and energy bumping up to 205. Expect clean, fun, little waves at Suicide Cliffs. It’s small, but it’s the best combo of shape and wind we get.
The second standout is further out on Friday July 24th. This one’s promising but less certain. We’re looking at a 5 ft southerly swell with an 11-second period, light north-northwest cross-offshore winds, and energy at 624. Conditions should be clean and the size is solid. If the long-range forecast holds, this could be a proper session.
Water temp is about average for the season – nothing wild there.
The rest of the second week, from July 20th onward, is a grind of fresh easterly cross-shore winds keeping things lumpy. There’s a marginal window around July 23rd with a 5 ft southerly swell and clean winds, but tide might mess with it. The 24th is your best long-range bet.
So: survive the first weekend, enjoy the tiny glass-off mid-week, and circle Friday the 17th and Friday the 24th as your real chances.
Rusty out.

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.
