The Lowdown
Alright, this is Rusty. Let's break down what's coming up at Suicide Cliffs.
Right now, there’s a little wait before things get going, but there’s some decent swell on the horizon.
We start on Thursday, August 13th. It’s not huge – a 1.1m swell from the southwest – but the wind is glassy and everything is clean. The wave energy is moderate (263). The water is about 29°, which is normal for this time of year. This is good, fun, manageable surf.
Friday the 14th keeps it going. Friday morning has a 1.0m southwest swell with glassy conditions, so you’re looking at clean waves. Friday afternoon the wind goes light cross-offshore, keeping things tidy.
Saturday the 15th is a mixed day. The morning looks small at 0.8m with glassy conditions, but the quality is just average. Keep an eye on the afternoon. A 1.0m southwest swell shows up with a slightly longer 9-second period, and the wind goes glassy again. That’s the best part of the day.
Sunday the 16th morning is still surfable with a 1.1m swell, but the wind picks up from the east-southeast, and it’s cross-shore. By the afternoon that wind strengthens to a moderate cross-onshore, and it gets choppy. From Monday the 17th right through to Friday the 21st, it’s rough. Strong winds, lumpy conditions, and just poor surf. Skip it.
Now, here’s the good part. Saturday, August 22nd sees conditions improve. The morning is a bit rough with a 1.6m south swell and cross-shore wind, but the afternoon turns it around. Swell drops to 1.2m from the south, the wind goes cross-offshore, and it cleans up nicely. The wave energy is moderate (360). This is a solid session.
But the real standout is Sunday, August 23rd. The morning brings a 0.9m southwest swell with a 10-second period and clean cross-offshore winds. Then the afternoon is the best of the whole run. Swell bumps to 1.1m from the southwest, the period stretches to 11 seconds – that’s real groundswell – and we get a gentle offshore breeze. It’ll be clean, lined-up, and perfect for Suicide Cliffs. Wave energy is moderate (350). That’s the one to chase.
After that, from Monday the 24th onwards, it dies off. Small, weak, and mostly average through to the end of the forecast. A few glassy mornings around the 25th and 26th with 0.6m swell, but it’s only very ordinary.
So, to sum it up: a clean start, a rough middle, then a strong finish on Saturday the 22nd and especially Sunday the 23rd. Go get it.
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.
