The Lowdown

Alright, let’s get into it. This is Rusty, and I’m looking at the next few weeks for Middles/Generals. It’s a pretty tough start to the outlook, I’m not gonna lie. We’ve got some proper grumpy conditions hanging around for a long stretch, but the second half of the period starts to turn things around. Keep the faith.

We kick off with a long, frustrating gap. From Tuesday the 15th all the way through to the morning of Wednesday the 23rd of September, the surf is just not happening. Some of those days have a bit of size, sure, with swell heights hitting 4 ft to 8 ft, but the wind is relentless – strong ENE breezes, mostly cross or cross-onshore, and the energy is a mess. It’s a real battle of a pattern. The swell energy is moderate to strong in that period (readings between 139 and 1303), but with those winds creating lumpy, choppy conditions, the surf quality is poor. For a beach-and-reef setup like this, it’s more of a kite surfing week than a paddle surfing week.

Now, Wednesday the 23rd of September afternoon things finally shift. The wind swings around to WSW at 3 mph, nearly glassy, and the cross-offshore breeze cleans everything right up. The swell hangs around 8 ft from the east with a 10-second period – that’s a proper groundswell, packing some punch. The energy is very high (1316), but at 8 ft, this is big enough to get exciting, maybe even a bit too much for beginners. The forecast says it’s excellent for experienced surfers, and I’m feeling it. That afternoon is the standout of the whole window.

Then Thursday the 24th keeps that thread going. Morning and afternoon both see clean conditions with light WSW to W winds at 6 mph, still cross-offshore. Swell sits at 8 ft from the east, period 9 seconds. The energy is still very high (1170 and 1084), but that consistent, clean combo will produce some proper waves. Another big day.

The rest of the run into late September gets more marginal again, but Saturday the 26th is worth a mention. Glassy conditions in the morning and afternoon with an ENE swell of 7–8 ft and an 8-second period. The combined energy is 924 (morning) and 779 (afternoon). The wind is dead calm – light air – so expect super clean, user-friendly conditions, though the waves will be a bit softer on the shorter period. It’s not the size or grunt of the 23rd, but for a fun, glassy session, it’s a solid pick.

Water temperature here is about 81°, which is pretty much bang on average for the time of year – no surprises.

So, if you’re waiting for the best, the window from the afternoon of Wednesday the 23rd through Thursday the 24th is where it’s at. That’s the one. Big, clean, powerful east swell with offshore wind – that’s the gold. The Saturday the 26th is a nice backup for a more relaxed, glassy day.

Rusty.
