Table - best surf conditions forecast for Suicide Cliffs over the next 16 days.
Alright, I’m looking at the charts for the next couple of weeks, and honestly, it’s a tough stretch for Suicide Cliffs. The first week is mostly a write-off, but there’s a real glimmer of hope the following Monday.
Right now, through to the end of this week, it’s pretty grim. We’ve got a big, raw 13ft SSE swell hammering in today (Sunday the 12th) with a howling 25 mph cross-on wind. That’s not surfable, that’s survival. The combined energy is massive at 6542, but it’s useless. Water temp is 85°, which is about normal for this time of year.
The next few days are a slow decline of a messy swell. Monday through Wednesday, it’s still onshore, with wave heights dropping from 8ft down to 4ft, but the wind keeps it choppy and blown out. Thursday the 16th things start to lighten up a bit, with the wind turning more cross-shore and the swell down around 4ft, but it’s only marginal. Friday the 17th is the same story.
The weekend of the 18th and 19th, the wind finally goes cross-offshore, but the swell just doesn’t have any grunt. We’re looking at 3ft to 3ft with a weak period of 8-9 seconds, and the combined energy is down around 112-225. It’s clean, but barely breaking.
Then, here’s the standout. Monday the 20th of July. This is the one to mark on your calendar. A new SW groundswell rolls in at 6ft to 7ft with a fantastic 12-second period. That’s proper, long-period energy. The combined energy jumps back up to 988-1023, and the wind is a clean, light cross-offshore breeze from the east. This is the best setup we’ve seen all outlook. The water will be calm, the waves will have shape, and for an exposed reef like Suicide Cliffs, that long-period SW swell is the magic number. The sets will be a bit lully, but the paddle out should be manageable. It’s a proper intermediate-plus wave at that size, so not one for the groms.
Tuesday the 21st still has some decent 6-6ft leftovers from that same swell, but the wind shifts to a moderate cross-shore, bringing a bit of chop. The energy is still high (934-1072), but it won’t be as clean as Monday.
After that, the surf drops off a cliff again. From Wednesday the 22nd right through the end of the 16 days, we’re back to small, weak waves under 3ft. The wind does get offshore on the 25th and 27th, but there’s no swell to use it. The energy is down to 99-230, so it’s basically flat.
So, to sum it up: the first 8 days are a bust. The only real window is the 20th of July. That Monday is the one. Get in the water, it’ll be worth it.

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.
