Annascaul Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.

Honestly, it’s a tough start. We’ve got Annascaul Rivermouth on the menu, and for the first several days, the conditions are just ordinary. The water is a touch warmer than normal at 64°, about 3° above average for this time of year, so that’s a small comfort, but the surf itself is struggling.

We kick off on Tuesday, August 25th, with a weak 4ft swell from the west, period at 9 seconds. The combined energy is moderate (214), but the wind is a light cross-off from the ESE at 6 mph, which keeps things clean. It’s surfable, but very ordinary. That afternoon, it drops to 3ft and the quality falls off a cliff. Wednesday morning is even smaller at 2ft, and from there, we hit a real dry spell. From Wednesday afternoon all the way through to the end of the month, the scores are all zeros. There’s a gap of several days with no real recommendations. The wind is mostly cross or cross-on, and the swell is tiny or non-existent.

We finally see some size come in on Monday, August 31st, with a 6ft west swell at 10 seconds, but the wind is a moderate cross-onshore at 12 mph, making it choppy and messy. The energy is strong (687), but it’s not a paddler’s dream. That trend continues into September. On Tuesday, September 1st, we get a big 10ft swell from the WSW, but it’s accompanied by a fresh onshore wind of 19 mph and rain. That’s big, over 8ft, so really only for the experts, and the wind is ruining it. The combined energy is very strong (1658), but it’s a battle.

The standout, if you can call it that, is not really a standout for clean surfing. The closest we get to a decent window is the morning of Wednesday, September 2nd. There’s a 10ft west swell, period 10 seconds, with a fresh cross-shore wind from the WNW at 22 mph. The energy is very strong (1495), but it’s lumpy and cross-chop. For a sheltered spot like Annascaul Rivermouth, this is more of a power session for experienced surfers. It’s just too big and messy for beginners.

Further out, on September 8th, we see a 10ft swell from the WSW with a very long period of 13 seconds. The energy is massive (4015), but the wind is onshore. That long period groundswell would usually be great for a rivermouth, but the wind is going to chop it up. The afternoon of the 8th is marginal, with an 8ft swell and lighter wind, but it’s still cross-onshore and fairly choppy.

Overall, this is a bleak run. The forecast is poor for the entire 16 days. If you’re desperate, the 2nd of September morning is the biggest and most powerful, but it’s a rough, expert-only session. The rest is mostly a write-off.

Rusty.
