The Lowdown
Alright, Rusty here again. Let's break it down for Suicide Cliffs. This is the only spot in the forecast, and it's a tough 16 days. Water temp is about normal for this time of year, nothing to write home about.
The first week is a total loss. From Thursday the 27th of August through the end of the month, it's all onshore and cross-shore winds with small, weak swell. The wave energy is low, around 100 to 200. Not worth your time.
Into early September, the wind goes offshore and strong, but the swell is tiny – 1ft to 2ft. It's clean, but you'll be scratching for a ride.
Then things get huge. On Wednesday the 2nd of September, a big southeast swell arrives – 12ft to 13ft with a 12-second period. But the wind is howling from the west at 34-37 mph, making a total mess. Wave energy is well over 4000. This is kite-surfing weather, not paddle surfing.
Thursday the 3rd and Friday the 4th of September go even bigger, with 23ft southeast and southwest swells. The wind is still strong and cross-shore. The report says the swell is too big for this break. Wave energy hits 18978 and 11850 – just massive, dangerous, and ugly.
The best chance comes on Saturday the 5th of September. The swell drops to a clean 7ft from the west-northwest, with a 11-second period. The wind turns light and cross-off, giving clean conditions. Wave energy is a solid 1521. This is the standout. Good for experienced surfers. It's a reef break, so that longer period will give you some proper, lined-up waves.
Sunday the 6th of September also has a shot. The morning shows 6ft from the southwest with a 13-second period and light, clean cross-off winds. Wave energy around 1062. Another solid option for the experienced crew, but it fades in the afternoon.
After that, it's done. From Monday the 7th of September, the swell drops to under 3ft with weak energy, going flat through the 11th. The wind is clean, but there's no swell.
So, the only real standout is Saturday the 5th of September, with Sunday the 6th a decent backup. Both mornings offer clean, solid waves at Suicide Cliffs, but it's for the experienced folks only. Everything else is a bust.
Rusty, out.
