The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a 16-day outlook for Suicide Cliffs, and I gotta be straight with you – it’s a rough stretch. The first week is a write-off for anything decent, and the only real glimmer of hope comes well into the second week.
Looking at the whole picture, we start with a whole lot of nothing. The first few days are a total bust. Saturday the 5th and Sunday the 6th are just messy with poor surf and strong onshore winds. Monday the 7th gives us a tiny bit of hope with offshore winds but the swell is way too small, barely 3 ft, to hold your interest. From Tuesday the 8th through Thursday the 10th, it flat-lines with tiny waves under 2 ft. That’s a painful gap of nearly a week with no real surf to speak of.
Then things get interesting, but tricky. On Friday the 11th, a new swell starts pumping in, but it’s straight onshore and the wave energy is climbing. By Saturday the 12th, we’re looking at a solid 8 ft swell from the SSE, with a period of 10 seconds and a combined energy reading of 1263 – that’s strong wave energy. The problem is the wind is onshore in the morning and cross-onshore in the afternoon. This is big, powerful, but messy surf. It’s going to be a beast, but only for experienced surfers; that 8 ft height is expert territory. The swell direction is S-SSE, which is not the optimum SW for this spot, so it’ll be a bit raw.
The actual standout – and I mean the only real standout in the whole outlook – is a bit of a long shot on Sunday the 20th. That morning, the forecast shows glassy conditions with a tiny 0.7 ft swell from the south. The wave energy is practically non-existent at 4, so don’t expect much. But if you’re a log or a longboarder, the glassy conditions are a gift. It’s a promise of smooth, clean water, even if the waves are more like ripple than surf. For a full-on session, the best of a bad bunch is the Saturday the 12th, but you’ll be battling the wind for a big, powerful wave. Keep your expectations in check, Suicide Cliffs is a tough bet this time around.
The water temp is about average for this time of year, so no need to dig out the thickest wetsuit just yet.
Rusty.

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.
