The Lowdown
Record: Trestles (Lowers)
Day 2, Wednesday: The ocean’s got a little pulse but it’s nothing to write home about. Early morning has a clean 2ft of SW swell with a 16-second period, which is proper groundswell – but it’s weak, with combined energy sitting at 271. Light SSW wind keeps it glassy, but honestly, it’s just too small to get excited. The water’s running 76°, which is a solid 9° warmer than normal for this time of year – that’s weirdly warm, even for here. Afternoon gets a touch more push at 2ft but the cross-onshore chop kills it. This is a day to sit on the beach, not fight it.
Day 3, Thursday: Still struggling. Morning has 2ft on it, but the 15 km/h SSW wind is onshore and it’s messy. The afternoon bumps to 3ft with a 18-second period, energy climbing to 478, but the WSW wind keeps it lumpy. Not worth paddling out for the scraps.
Day 4, Friday: Slight improvement but still marginal. Morning brings 3ft of SSW swell, period 17 seconds, energy up to 776. Light cross-onshore wind though – just enough to put a wrinkle on it. Afternoon pushes to 4ft with energy hitting 992, but the same cross-onshore breeze holds it back. If you’re desperate, you could get a few, but it’s not clean.
Day 5, Saturday: Now we’re getting somewhere. Cloudy skies, 4ft of S swell with a 14-second period, and morning wind drops to a whisper at 5 km/h – the ocean’s nearly glassy. Energy’s jumped to 1108, which is finally moderate. It’s still a bit weak, but the conditions are making it work. Afternoon holds 4ft with energy at 1136, but the breeze swings cross-onshore and roughens it up. Get out early.
Day 6, Sunday – The standout: This is the one. Sunday morning is firing. 6ft of SSW groundswell, 14 seconds, with a light NE offshore wind – that’s the kind of clean, groomed wave you dream about. The combined energy is storming at 1506, and the report says it’s excellent for experienced surfers. This is a big, powerful swell – over 5ft so it’s not for beginners, but if you know what you’re doing, you’re in for a treat. Lowers will be handling this beautifully, with lines wrapping through the reef. Afternoon drops to 7ft but the wind swings onshore and it gets lumpy. Don’t snooze on that morning session – it’s the best on offer in this whole stretch.
Day 7, Monday: Back down a notch. 6ft in the morning, but the W wind is cross-onshore and it’s not clean. Energy’s still solid at 1141, but the surface is bumpy. Afternoon drops to 5ft and gets choppier. There are waves, but they’re ugly.
Day 8, Tuesday: Fading and blown out. Morning has 5ft but the cross-onshore wind is on it. By the afternoon, the WNW wind bumps to 20 km/h and it’s just a mess – 5ft of lumpy, wind-blown stuff. Not your day.
Day 9, Wednesday: Swell’s backing off. Morning is 4ft with a shorter 11-second period and a light onshore wind – meh. The afternoon drops off a cliff to 2ft and gets battered by 20 km/h cross-onshore wind. Forget it.
Day 10, Thursday: Small and weak. 3ft of WSW swell, but the wind is on. Energy’s falling to 587. Not worth the effort.
Day 11, Friday: Still struggling. 3ft, onshore wind, energy down to 514. It’s flat-ish and junky.
Day 12, Saturday – Day 17, Thursday: The long-range window is grim. Swell keeps dropping from 3ft down to 1ft. There’s a brief pulse on Day 17 (September 17th) where the period jumps to 24 seconds – that’s some long-period energy – and the swell bumps to 3ft with energy at 741. But it’s cross-onshore and the size is pitiful. You’re looking at a solid gap from around Day 9 through Day 17 with almost nothing rideable. This is a real drought.
Overall, Sunday morning is your absolute window. Don’t expect anything else to come close. The rest is a waiting game.
