The Rivermouth Surf Forecast and Surf Report

Alright, let’s talk about the Rivermouth.

This is a sheltered sandbar that only really breaks on a good SSW swell, and it’s a spot that rarely turns on. For the next two weeks, we’re looking at a lot of small, average days with a few windows of clean, rideable waves—but honestly, nothing that’s going to have you calling in sick. The water’s sitting at 61°F, which is a touch warmer than usual for this time of year. Nothing crazy, but you’ll notice it on a calm morning.

The first real chance to get wet kicks off Tuesday the 8th, early. We’ve got a clean 3ft south swell with a 12-second period, light SW wind, glassy surface. It’s surfable, but pretty ordinary—weak energy in the water (375). The afternoon goes cross-on and bumpy, so don’t bother.

Wednesday the 9th looks better in the afternoon. Swell drops to 2ft but the period jumps to 19 seconds—proper groundswell. Light WNW cross-off wind, clean faces. Still not big, but the shape should be fun for a log or a mid-length. Morning’s flat-ish and glassy but tiny (1ft). Combined energy’s still moderate (434).

Thursday the 10th and Friday the 11th mornings are messy—light cross-on wind, lumpy texture, questionable tides. Friday afternoon cleans up with a cross-off and 3ft at 15 seconds, but it’s not going to blow your mind. Energy’s moderate (552).

Saturday the 12th starts okay but the wind picks up hard from the NW at 25 km/h by afternoon—choppy, blown out. Sunday the 13th has a glassy morning with 2ft but it’s weak (229). Not worth the paddle.

Now, here’s the one standout in this whole stretch. Monday the 14th is small, but Tuesday the 15th morning brings the biggest swell of the run: 5ft from the WNW with a short 8-second period. The wind is glassy, the surface is clean, and combined energy hits 517—moderate but pushing. Problem is, that short period means it’ll be a bit crumbly and sectiony at a sandbar like this. Still, it’s the biggest, cleanest surf you’ll see in the whole two weeks. If you’re an advanced surfer, that’s your window—just don’t expect perfection.

After that, it fades fast. From the 16th through the 23rd, we’re mostly in the 2ft to 3ft range with cross-on winds and lumpy conditions. A few mornings are glassy but too small to do much. The 21st has a clean 3ft with a 17-second swell, but it’s marginal. Honestly, if you’re not a local who knows every ripple of this river mouth, I’d sit most of it out.

So overall: not a great run. A couple of mornings—the 9th afternoon and the 15th morning—are your best bets. The rest is either too small, too bumpy, or just plain ordinary. Keep expectations low, and if you’re a kiter, the windy afternoons around the 12th and the 15th might actually look more interesting than surfing. But for paddle surfing? This is a waiting game.

Rusty out.
