Rivermouth Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s break down Rivermouth over the next 16 days. It’s a mixed bag, but there are some clean windows if you know when to go.

The first real surf to get excited about is this Saturday afternoon, the 25th. It’s not big, but it’s clean. We’re looking at a 4 ft SSW swell with a solid 14-second period. That’s proper groundswell, and the wind is glassy, dead calm. The water’s about average for this time of year. The energy is moderate (771). This is the standout for the first week—clean, workable waves for a beginner-friendly spot, but fair warning, Rivermouth can get a crowd sometimes.

Saturday morning is a write-off with cross-shore wind and questionable tide. Don’t bother. Sunday the 26th is a total dud—windy and messy. Monday the 27th is even worse with poor surf and strong winds. We’ve got a few days of nothing much.

Then Tuesday the 28th afternoon hits. This is the real deal for experienced surfers. The swell bumps to 4 ft from the SSW, period hits 15 seconds, and it’s glassy again. The energy is strong (1280). That’s long-period groundswell, which will wrap nicely into the river mouth, but it’s a bit too much for the groms. The morning is rainy and onshore with a 7 ft SSE swell—too big and messy, so skip it.

Wednesday the 29th has a morning pulse of 6 ft from the south, but the wind is onshore and it’s raining. Not great. The afternoon cleans up but the wind goes cross-shore and the swell drops. The rest of that week into early August is mostly blown out by strong NE winds and building east-southeast swell. By Friday the 31st, we’re looking at 6 ft to 7 ft of short-period junk with moderate cross-shore winds. That’s not for paddle surfing—more of a kite day if you’re into that.

The first weekend of August (the 1st and 2nd) gets big. Saturday the 1st sees 8 ft to 8 ft ESE swell, but it’s still cross-shore and choppy. Sunday the 2nd goes huge—10 ft from the east with a 12-second period. The energy is massive (3969). That’s expert-only territory, and for a river mouth, it’s likely just too big and closing out. The wind is light and cross-shore, but the size is the problem.

The second week settles down. Monday the 3rd and Tuesday the 4th offer cleaner conditions with lighter winds and 6 ft to 7 ft ESE swell, but the period drops, and the quality is marginal. Wednesday the 5th morning is a glassy little highlight—5 ft from the ESE, light wind, clean. That’s a nice little session for the more experienced crew. Thursday the 6th morning brings a 3 ft SSW groundswell with a 16-second period and clean offshore wind. That’s a gem for the patient surfer, light and long.

The last few days, from the 7th to the 9th, are a mixed bag of small SSW swell and then a big 12 ft pulse on the 9th morning (Sunday the 9th) that’s again too big for this break. The energy is extreme (4349), but that’s for tow-in or big-wave chargers, not the average surf.

Overall, the best on offer is Saturday afternoon the 25th for the glassy, clean conditions, and Tuesday afternoon the 28th for the bigger, more powerful groundswell for experienced surfers. The long-range stuff (first week of August) is promising but less certain—keep an eye on it.

Rusty.
