The Lowdown
Alright, let’s break it down for Suicide Cliffs.
First off, don’t bother suiting up for a while. The water is 82°, which is about 3° cooler than the usual for this time of year – you’ll definitely notice the chill.
From Monday (20 July) through Saturday (25 July), it’s all poor. Tiny swell, combined energy often under 100 (26 to 126), and mostly cross-onshore wind making it choppy. Thursday (23 July) goes glassy, but the swell is only 1 to 2 feet – no good. Friday (24 July) cleans up with a light cross-offshore breeze, but the swell is still only 1 foot. Not worth the drive.
Then Sunday (26 July) kicks off a big SE swell. It jumps to 10 feet in the morning with a 13-second period, energy at 2419 – that’s strong. By the afternoon it’s 12 feet, 13 seconds, energy at 4176. Wind is cross-shore from the east, gusty, with thunderstorms possible. Over 8 feet, this is expert-only. The reef will handle the long period, but the cross-shore wind will make it lumpy.
The real standout is Monday (27 July) and Tuesday (28 July). Monday morning we’re talking 20 feet from the SSE with a 15-second period – that’s very long period groundswell. Combined energy is a massive 16531. Wind is cross-shore from the ESE at 28 mph, with cross-chop. It’s going to be a beast. Tuesday afternoon the swell is still 18 feet from the SSW, 13 seconds, energy 18753, but the wind goes straight onshore from the SSE at 22 mph. This is big, raw, and dangerous – for experts only.
After that, Wednesday (29 July) and Thursday (30 July) drop fast, but the wind stays messy. Friday (31 July) through early August is small and average. By Monday (3 August) there’s a light cross-offshore breeze from the NE and 4 feet of swell from the SW – surfable but nothing special.
Bottom line: the only real window is the 27th and 28th for serious size, but it’s not clean. Everything else is flat or poor.

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.
