The Lowdown
Alright folks, Rusty here.
Let's be honest, the next week and a half at Suicide Cliffs (reef) is a write-off. We’ve got a lot of stormy weather, howling winds, and some seriously dangerous swell sizes coming through. There’s a bit of a gap before we see anything worthwhile.
The first real glimmer of hope shows up on the morning of Tuesday, September 2nd. The wind is howling from the north at 25 mph, blowing straight offshore, so the face will be clean. A 7ft SE swell rolls in with a period of 11 seconds, but the combined energy is a solid 1194, meaning there’s some power. This one is for experienced surfers only, as paddling in will be a battle.
Then, things get wild. On Thursday morning, September 3rd, the forecast shows a massive 20ft SE groundswell with a 14-second period, and the combined energy is a staggering 15245. The wind is a gale-force 43 mph offshore. This is a true beast and only for the most experienced big-wave chargers, if anyone at all. It’s too big for this break.
After that, the swell slowly drops through the rest of that week, but the wind is still messy. The standout window finally arrives on Monday, September 7th. The morning brings a 4ft SW swell at 12 seconds, with a clean offshore breeze from the north at 12 mph. The water is a warm 84°, which is about average for this time of year. This is the best call for the period: clean, manageable, and the forecast says "very good surf conditions."
The following morning, Tuesday, September 8th, is also a cracker. We’ve got a 8ft SE groundswell with a 12-second period, combined energy of 1610, and a gentle 9 mph offshore wind. This is "excellent surf conditions for experienced surfers." The afternoon holds steady with a 7ft SSE swell. This is your other standout.
So, to sum it up: the first week is a washout. The best bet is the morning of Monday, September 7th, for a solid, clean session. The experienced crew should also pencil in the morning of Tuesday, September 8th. The 3rd is for the madmen only.
Stay safe out there.

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.
