The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up for Suicide Cliffs. I’ve got the full 16-day run in front of me, and I’ll be straight with you – it’s a long wait for anything worth paddling out for.
The first week and a half is pretty much a write-off. We’ve got tiny, weak swell from the 1st through to the 6th of August, with wave energy barely registering (10 to 26). The water’s a touch warmer than normal at 86°, about 2° above average for this time of year. But honestly, with heights barely hitting 1.0ft to 1ft and those poor surf conditions, you’re not missing a thing. Even with clean, offshore winds on the 3rd, there’s just no power in the water to work with.
Then it gets weird. On the 7th of August, the swell absolutely explodes. We’re looking at a massive 36ft to 38ft SW groundswell, with a very long period of 12 to 13 seconds. The combined energy is off the charts (35,925 to 45,784). But here’s the kicker – the wind is a violent storm force offshore in the morning and storm force cross-off in the afternoon. That kind of power at Suicide Cliffs is for absolute experts only, and even then, it’s dangerous just to get out. The forecast says it’s too big for this break, and I’m not arguing. This is not a paddle situation.
The 8th through the 12th of August stays big – between 18ft and 3ft – but the wind switches hard onshore and stays that way, with hurricane-force gusts on the 8th. It’s blown-out, messy, and the wave energy is still very high but completely unsurfable.
We finally get a slight improvement from the 13th of August onward. The swell drops to a more manageable 3ft to 4ft, with periods around 8 to 11 seconds. The wind eases to a moderate to gentle breeze, but it’s cross-shore or cross-onshore, leaving a chop on the surface. The energy is moderate (132 to 300), but the conditions are still marginal. By the 16th of August, we see a little light cross-shore wind and the surf is just questionable – a 1 out of 10 on the score. It’s not really on.
So, what’s the standout? Honestly, there isn’t one for the average surfer. If you’re a big-wave chartered expert with a death wish, the 7th of August is your day, but you’re on your own. For everyone else, the whole 16-day window is a dud at Suicide Cliffs.
Keep your eyes on the forecasts – they can change.
Rusty.
