Sandy Mouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at Sandy Mouth over the next couple of weeks.

First off, we’ve got a quiet spell to start. The water is sitting at 67°F which is much warmer than normal for this time of year – a nice bonus if you’re just getting wet – but the surf itself isn’t giving us much early on.

From Friday the 14th through Monday the 17th August, it’s all small and weak. Wave heights are between 1.0ft and 3ft, with periods of 7 to 9 seconds – not much push. The combined energy is low, barely cracking 104 at best, and mostly under 100. Winds are onshore or cross-shore most of that time, so it’s gutless and messy. Not worth paddling out.

Tuesday the 18th sees a little more size – 4ft – but the period drops to 7 seconds and the wind is cross-onshore and choppy. Energy hits 158, but quality is still poor. Wednesday the 19th pushes to 5ft with a short 6-second period – steep and wind-affected, energy around 193 to 200. Still too sloppy for a good session.

Then we hit a long, flat stretch from Thursday the 20th right through to Wednesday the 27th August. Swell heights mostly stay under 3ft, often dropping to 0.3ft or 1.0ft. There are some cleaner windows with offshore winds on the 23rd, 24th, and 25th, but the swell is just too tiny to do anything with. Energy values are pathetic, often in the teens or single digits. A real dead spell.

Finally, something stirs on Thursday the 27th. Morning brings clean, cross-offshore winds and a 3ft west swell at 8 seconds. Energy is 77, and the notes call it "surfable but very ordinary" – honestly, that’s the best we’ve seen in a week and a half, but still nothing to get excited about.

Now, the real standout, but you’ve got to wait. On Friday the 28th of August, it gets proper spicy. A major west swell hits at 15ft with a long 12 to 13-second period. The combined energy explodes to 5791 and then 6827 – that’s very strong. Wind is clean and cross-offshore from the NE at 25 mph. But the catch: the notes say the swell is predicted to be too big for this break. Over 8ft, this is strictly for experts only. The long period will make it power-packed, and at a beach break like Sandy Mouth, the sets could just close out. Saturday the 29th is still massive at 12ft, but the wind swings cross-on in the afternoon and gets choppy.

So overall, almost nothing for two weeks until that huge swell at the end. If you’re an expert paddler who loves a challenge, the 28th is the only day – but do not take it lightly, that’s a heavy, powerful ocean. Everyone else, save your energy. Rusty.
