The Lowdown

Alright folks, Rusty here. Let's have a look at what's shaping up for Navarro Rivermouth over the next couple of weeks.

First off, the water temp is sitting at about 57°, which is a touch cooler than usual for this time of year, but nothing too crazy. Now, don't get your hopes up for the next little while. We're looking at a pretty rough start. For the first several days, from Monday the 14th through to Sunday the 20th, the surf is going to be poor to marginal at best. The wind is mostly a cross-onshore breeze, and the wave energy is moderate but messy, with readings around 400 to 1400. The swell is short-period, around 8 seconds, so it’s just gonna be a bumpy, choppy mess. A few days, like Monday the 14th, see swell over 8 ft, but with that wind, it's only for the experts, and even then, it won't be pretty. Honestly, for a beach break like this, with that much wind and chop, it looks more like a kiteboarding session than a paddle-surf session.

We finally get a bit of a glimmer on Monday the 21st of September. The swell bumps up to 8 ft from the NW, and the wind lightens up. It's still cross-onshore, but it’s a light breeze. The wave energy is strong, hitting around 1325. It's still just a marginal call, but it's a step in the right direction.

The standout, and I mean the only real standout in this whole run, looks like Tuesday the 22nd of September. The morning has a light cross-onshore wind with a 5 ft NW swell, but the real magic is the afternoon. The wind goes glassy – absolutely dead calm – and the swell is a solid 8 ft from the NW with a period of 10 seconds. The energy is pumping at 1551. This is going to be clean, powerful, and for experienced surfers only. That's your best bet, right there. The following morning, Wednesday the 23rd, has another glassy window with a smaller 5 ft swell, but it won't have the same punch.

After that, things fade off again. From Thursday the 24th through to the end of the period, we're back to poor conditions with cross-onshore winds, and the swell drops down. There's a big NW pulse on the 29th of September with swell up to 10 ft and energy over 2800, but the wind is on it, making it a messy, blown-out affair.

So, to sum it up: the first week is a write-off. Your one and only true standout is Tuesday afternoon, the 22nd of September, when the wind goes glassy and the swell is solid. After that, it’s slim pickings again.

Rusty.
