Annascaul Rivermouth Surf Forecast and Surf Report

Alright, Rusty here. Let’s get into it. We’re looking at Annascaul Rivermouth, and to be straight with you, the next week and a half is a bit of a write-off. You’ve got a long, flat and messy run from now, the 26th of July, all the way through to the 3rd of August. The swell is tiny, wind is all over the shop – mostly onshore or cross-shore – and the wave energy is weak, often below 100 or just scraping into the low hundreds. It’s one of those spells where you’re better off doing something else. The water is sitting at 64°F, which is a touch warmer than normal for this time of year, so if you do have a paddle, at least it’s not freezing.

Now, the first real glimmer of something worthwhile shows up on Tuesday the 4th of August. It’s not a full-blown classic, but it’s the best we’ve got. Tuesday morning, the wind goes glassy – a slight air from the WNW – and we’ve got a 7ft swell out of the WSW. The combined energy is a moderate 659. The swell period is 9 seconds, so it’s a decent groundswell, and with those glassy conditions, the break should look clean. Tuesday afternoon stays good: a touch of cloud, a light offshore from the N, and the swell drops a bit to 6ft but the energy actually jumps to 888. Clean conditions again. Both sessions are surfable and fun – not epic, but solid intermediate waves.

Then Wednesday the 5th of August, things crank up a notch. That morning we’ve got an 8ft swell from the WSW with a 6 mph offshore breeze from the NNE. Energy is a strong 967. That’s a proper amount of water, and with offshore wind, the Rivermouth will be groomed. This is getting into expert territory, though – over 8ft – so if you’re not comfortable in overhead, punchy stuff, sit this one out. Wednesday afternoon is the real standout: a 10ft swell from the W, still a cross-offshore breeze from the N at 9 mph, and the energy jumps to a very strong 1316. The Rivermouth is a sheltered spot, and it’s setup for SW, so the W direction is not perfect, but with that much power and clean wind, it’ll still produce some excellent, heavy waves. Crowds are sometimes an issue here, so expect a few locals out.

After that, it drops off quickly. Thursday the 6th and Friday the 7th of August are tiny again and not worth the paddle. Saturday the 8th sees a little bump from the SW around 5ft but with onshore wind, so it’s messy. The rest of the run stays small and average.

If you’ve got a kite, the 5th of August with that strong wind and big swell might be more your thing than a paddle board. But for the surf, your window is Tuesday the 4th through Wednesday the 5th. Make the call, get out there.

Rusty.
