The Lowdown
Alright folks, Rusty here. Let's talk about what we've got lined up for the next couple of weeks. We're looking at a pretty lean stretch overall, so keep your expectations in check.
We're kicking things off with a real slow start. The first week is looking like a write-off, unfortunately. We've got tiny swell and mostly onshore or cross-onshore winds making a mess of things. You'll see a little bump in energy on September 21st, with a 4ft east swell (combined energy of 163), but the conditions are only rated as ordinary. It's not going to be anything to write home about.
The real standout, the only one worth circling on the calendar, is the morning of Saturday, September 26th at 13th Ave South Surfside. The wind will be light and cross-offshore from the northeast, keeping things clean. We'll have a 3ft swell from the east-southeast with a period of 9 seconds, giving us a moderate energy level (combined energy of 257). It's not a massive day, but given the conditions, this is the best we're going to see. Keep in mind this is a beginner-friendly spot, and crowds are possible here, so get there early for a chance at a clean bank to yourself. The water temperature is sitting at 83°, which is about a degree warmer than average for this time of year, so it's pleasant.
After that, the surf quality drops off again heading into the final days of the month. The 27th and 28th have some small, clean waves in the morning, but the energy is low and the forecast is ordinary at best. The long gap of poor surf before the 26th and the quick drop-off after is what we have to work with. The swell direction is from the east-southeast to southeast, which is close to the optimum for this spot, so when the energy does show up, it's in the right direction.
This isn't a classic run, but that Saturday morning is your window. The rest of the time, the setup is more suited for a kite than a paddle.
Rusty.
