The Lowdown
Alright, Rusty here again. Let me break it down for Suicide Cliffs in feet and miles per hour.
For the full 16-day stretch, we’re looking at a pretty flat outlook with mostly rough, onshore wind. Swell heights stay small – around 2 to 3 feet for the first few days, dropping to 1 foot or less by midweek. The swell direction (SW) is good for this spot, but the period is short, mostly 7 to 9 seconds, so the waves don’t have much push. The combined wave energy numbers are mostly under 200, a lot of days under 100 – that’s weak. Wind is cross-onshore from the WSW or SW, blowing at 12 to 15 mph on Friday the 17th and Saturday the 18th, so you’re dealing with chop. The water temp is about 81°, which is 4° colder than normal for July – that’s a noticeable, cold anomaly.
Sunday the 19th morning has light onshore wind from the south, but the swell is still only about 3 feet with short period. From Monday the 20th, it really fades – swell drops to 2 feet or less, and it stays that way through most of the second week. On Thursday the 23rd, the wind goes glassy in the morning and clean cross-off in the afternoon, but with just 1 feet of swell, you’ll be praying for a ripple. That clean wind but tiny swell holds through the 26th. Then things get rowdy around July 28th: a jump to 8 feet of swell (combined energy 641) but the period is only 7 seconds, and the wind is near gale force from the west, cross-onshore and completely blown out. That’s a heavy, messy, expert-only day – but more likely a kitesurfing day. The 29th and 30th drop to 5 to 7 feet but still with fresh to moderate cross-onshore wind, lumpy and choppy. By August 1st, we’re back to 2-foot swell with light cross-shore wind, but nothing worth the drive.
Honestly, there’s no standout. The best chance for clean conditions is the 23rd and 24th with glassy or clean offshore wind, but there’s zero swell to ride. The only real swell pulse is the big, windy mess on the 28th. It’s a long, quiet run with one gnarly day that’s not for the faint of heart.
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. 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.
