Rivermouth Surf Forecast and Surf Report

Alright, Rusty here.

We’ve got a solid run of waves coming, but it’s not all smooth sailing. The first solid days are on Tuesday the 14th, but we’ll get to that. The real standout, the one you’ll want to circle on the calendar, is the window around the 21st and 22nd – that’s where the magic is.

Let’s start with the opening act. Tuesday morning the 14th at Rivermouth is a cracking start. You’re looking at clean 6 ft of ESE swell, with a period of 9 seconds and moderate wave energy (544). The wind is a glassy 3 mph from the NE – that’s near-perfect conditions. The water’s a bit colder than normal, sitting at 65°, which is a notable drop from average for this time of year. Afternoon holds up just as well, with a slight shift to an E swell at 6 ft and still glassy. It’s a beginner-friendly wave, and it’s very consistent, so you can get plenty of rides. But be aware, crowds are possible here.

The rest of the week goes a bit sideways. Wednesday the 15th gets a cross-shore wind that chops things up, and the swell quality drops. Thursday the 16th has a bigger energy reading (744) from a 4 ft E swell, but the cross-onshore wind kills the surface. Friday the 17th drops off further, and the weekend is messy with moderate cross-shore breezes and poor conditions. Basically, from Wednesday the 15th through Sunday the 19th, it’s a bit of a write-off – not worth paddling out unless you’re desperate.

Now, here’s the good stuff. Monday the 20th afternoon starts to show some life, with a jump in energy to 6 ft from the S and a very strong energy reading (1079), but the cross-shore wind keeps it from being perfect. The real change comes Tuesday the 21st. Tuesday morning, the wind goes cross-offshore from the NNW at 9 mph, cleaning up a solid 5 ft SSW groundswell with a long period of 13 seconds. That’s proper energy (1061). Tuesday afternoon gets even better: the wind drops to a slight 3 mph from the NNE, still cross-off, and the swell period stretches to a very long 16 seconds, pumping out 2020 energy units. This is top-tier for experienced surfers – the long period will make for powerful, well-shaped waves at this river mouth, but it might be a bit much for beginners.

If you can wait, Wednesday the 22nd is the absolute peak. Wednesday morning is glassy, no wind from the N, and the swell hits 8 ft from the SSW with a 14-second period. The combined energy is a massive 2612 – that’s strong to very strong wave energy. This is for experts only. Wednesday afternoon drops a bit to 6 ft, but the wind goes cross-onshore, so the morning is the clear pick.

After that, the surf fades again. Thursday the 23rd has strong, clean offshore wind from the SW at 25 mph, but with only 4 ft on offer, it’s not worth the hassle. The following week shows some small, inconsistent swells and mediocre winds, with a few moments on Saturday the 25th morning (clean 4 ft) and Monday the 27th morning (glassy 3 ft) that look okay for a longboard.

So, here’s the bottom line: Rivermouth is your only game in town, and it’s a good one. The standout window is Tuesday the 21st through Wednesday the 22nd. If you’re an experienced surfer, don’t miss Wednesday morning the 22nd – that’s the session. The setup is more interesting for paddle surfing than kiting, given the long-period groundswell and clean conditions.

Rusty.
