Sandy Mouth Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s on the table for Sandy Mouth over the next couple of weeks.

Right now, the surf is pretty much a non-event. We have a consistent run of poor surf conditions with messy, choppy winds and not a single standout session for the first ten days or so. The water temperature is 65°, which is much warmer than normal for this time of year, so at least you won’t be freezing your ass off if you paddle out in the junk.

We start on Friday the 11th of September with some knee-high west swell at 4 ft, but a cross-onshore wind from the northwest at 9 mph keeps it choppy. That’s the story for the following days – a lot of wind, a lot of chop, and weak to moderate wave energy (225 to 353). The swell bumps up to 5 ft on Saturday the 12th, but it’s a fresh cross-onshore wind at 19 mph, which will just ruin it. Sunday the 13th sees some clean onshore wind early, but it’s still poor conditions. A bit more energy (379) on Sunday morning but it’s not translating to anything good for a surfer. That’s a solid gap of about a week with nothing worth getting wet for.

Things start to look up around Monday the 21st of September. Monday morning has a nice onshore wind, 4 ft west swell with a long period of 11 seconds (groundswell), and moderate energy (274). But the real flicker of hope comes on Tuesday the 22nd of September. Tuesday morning, we’ve got a 3 ft west-northwest swell with a 10-second period, light east-northeast wind at 6 mph blowing offshore, and the wave comment says “clean.” The combined energy is moderate at 236. This looks like clean, surfable waves for intermediate surfers. Tuesday afternoon gets even better: 3 ft west swell, 12-second period (nice groundswell), and a light north-northeast breeze at 3 mph that’s cross-offshore. That’s clean again. The water will still be warm. This is the best on offer in the whole outlook – a day of clean, lined-up west swell with good period.

After that, Wednesday the 23rd is smaller and weaker, but Thursday the 24th of September is a bit of a wildcard. Thursday morning kicks up to 6 ft west swell with a 10-second period and a moderate cross-offshore wind from the south-southeast. The energy jumps to 632 (moderate-strong). It’s rated “marginal” but the wind is clean. That 6 ft is getting a bit chunky for beginners, but for the intermediate crowd it could be a good morning. However, Thursday afternoon has a very long period west-northwest swell of 15 seconds, pumping to 5 ft, with massive energy of 1366 (strong). The wind turns cross-onshore though, and it’s called “marginal” – a long-period west swell at a beach break can get a bit shifty and close out, so eyes open if you go.

Friday the 25th has a solid 5 ft west-northwest swell with a 12-second period and gentle cross-shore wind, moderate energy (608). It’s marginal according to the notes, but it could offer some fun ones if the tide is right. Saturday the 26th of September closes the outlook with a 4 ft west swell, 9-second period, light cross-offshore north-northeast wind at 6 mph, and the comment says “expect good surf conditions.” That’s a nice little clean session to end on.

Bottom line: the first ten days are a write-off. The standout is Tuesday the 22nd of September – clean banks, offshore wind, consistent west swell. Thursday the 24th morning is promising too but more of a challenge.
