The Lowdown
Alright, folks, Rusty here. Let’s talk about the local surf for the next couple of weeks, and I’ll be straight with you—it’s looking flat.
The first real chance for a wave doesn’t show up until Tuesday, September 8th, so you’ve got a full week of nothing from the start. The water is a warm 85°F, which is about average for this time of year, so it’s comfortable.
The best option, and honestly the only one worth talking about, is Tuesday morning, September 8th. The swell is tiny, just 3ft from the NE, but the wind is glassy with a light SSE breeze. The combined energy is weak at 89, but for this dead stretch, it’s the best we’ve got. The break is a beach and reef setup, and it breaks very consistently, so you’ll find a wave. Crowds are possible, so you might have some company.
After that, Wednesday morning, September 9th has a little more energy at 113, but the swell drops to 2ft from the ENE. The wind is dead calm and glassy. Again, it’s surfable but nothing to write home about. The swell period is 10 seconds, so it’s a weak groundswell, but it’ll be clean.
The rest of the period is a washout. Swell sizes stay between 0.7ft and 1ft, with onshore or cross-shore winds and zero scores. The combined energy stays below 100, often in the teens or single digits. There’s a morning on Saturday, September 12th with a clean cross-offshore breeze, but the swell is only 1ft—barely a ripple.
If you’re keen, the morning of the 8th of September is your best chance, but keep it real. This is a quiet run for the area, and it’s normal. Forecasts can change, so don’t give up.
Rusty.
