Annascaul Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s in store for the Annascaul Rivermouth over the next couple of weeks. I gotta be straight with you right from the start: this run is rough. The surf window is going to have some pretty big gaps, especially in the first week, so patience is going to be the name of the game.

For the first several days, through the end of August and into the start of September, it’s mostly a write-off. We’re looking at tiny, weak swells (the combined energy is down in the double-digits, like 32 at best) with onshore or poor cross-winds. There’s a little bump on Tuesday the 26th with a 3 ft westerly swell, but the conditions are described as “very ordinary,” – not worth getting wet for. We then hit a period with virtually nothing until we see a real pulse of energy showing up. The middle of the first week of September brings some stronger, but messy, swell. On Monday the 2nd of September, the swell jumps to 12 ft from the WNW, but the wind is a strong cross-shore, ruining any chance of quality. It’s honestly looking more like a kite-surfing setup than a paddle session.

Now, we do have one true standout that will make the wait worthwhile. For the morning of Saturday the 5th of September, mark it in your calendars. That morning, we’re looking at some absolute gold. The swell is a solid 13 ft from the west, with a period of 11 seconds, and the combined energy reading is a massive 3876 – that’s proper power. But the real story is the wind: it’s glassy, coming out of the SE. For a rivermouth that’s sheltered, this offshore breeze is going to groom it into something special. However, at 13 ft, this is expert-only territory. It’s going to be big, powerful, and a whole lot of paddle. The water temperature is sitting about 2° warmer than usual, which is a touch above average for this time of year, a bit of an extra treat.

The second week gets wild, but not in a good way for most of us. Monday the 7th of September is honestly a monster. We’re talking a 41 ft swell from the west with a 17-second period and an astronomical energy reading of 94277 – that’s barely surfable for anyone, even the pros. It’s simply too big. The swell then drops back, and the only other real highlight comes on the morning of Tuesday the 8th of September. You’ll get a clean 10 ft groundswell from the WSW with glassy southerly winds, offering very good surf. It’s still a big wave, but it’s a much friendlier prospect after that 41-foot beast. For the rest of that week, it’s a mix of messy cross-winds and choppy conditions.

So, to wrap it up: the first week is a bust with a massive gap in quality. Your single best call is the morning of Saturday the 5th of September for the experts. If you're a strong intermediate, keep your eyes on the morning of Tuesday the 8th. A long wait for some serious power.

Rusty.
