Annascaul Rivermouth Surf Forecast and Surf Report

Right then folks, Rusty here. Let's have a proper look at what's on the cards for Annascaul Rivermouth over the coming days.

Overall, it's looking like a challenging stretch of surf ahead, especially for the next week or so. The Rivermouth is pretty sheltered, so it takes a certain kind of swell to really get it going, and most of this forecast period is dominated by onshore and cross-onshore breezes, which will keep things choppy and messy. We've got a bit of a wait on our hands for anything truly worth paddling out for.

Looking at the immediate future, Sunday the 30th of August and Monday the 31st are write-offs with poor conditions and bumpy, onshore wind. A 6ft to 5ft swell from the WSW is there, but the wind ruins any chance of a clean wave. Tuesday and Wednesday are much the same story—onshore winds and poor surf. The swell builds through Wednesday, hitting 8ft on Wednesday afternoon, but it's all cross-onshore and choppy. The combined wave energy is moderate to strong during this period (619 to 807), but it's completely wasted with the wind.

Then we hit a real rough patch. Thursday the 3rd sees a big jump to 12ft to 13ft from the W with strong energy (2464 to 3736), but it's all cross-onshore, choppy, and way too big for most. Friday the 4th is a write-off with tiny, messy surf and howling cross-onshore winds, dropping to a mere 1ft with 54 energy.

The weekend of the 5th and 6th brings the swell back up, but again, the wind is a problem. Saturday morning sees 10ft from the WSW and light winds, but they are cross-onshore, leaving the surf marginal at best. Sunday the 6th and Monday the 7th are similar—plenty of swell (8ft to 8ft) but onshore breezes. The water temperature is about average for the time of year, so no surprises there.

There's a lull coming in after that. Tuesday the 8th and Wednesday the 9th are basically flat and blown out by strong winds. You won't even need a board for those days.

Now, keep your eyes on the horizon. The real standout looks like it could be Saturday the 13th of September. That morning we are expecting clean, offshore winds from the ENE with 10ft of solid W groundswell and very strong energy (1651). The period is a long 10 seconds, suggesting proper, powerful waves with good shape. The wind looks offshore all day, with Sunday afternoon showing light NE breezes. This has the potential to be *the* session of the outlook, but being two weeks out, it’s a promising one to keep a close eye on as it gets closer. Crowds at the Rivermouth are sometimes an issue, and with a setup like this, it’ll get busy.

For anyone who isn't an expert, the 10ft size will be a handful, and the long-period groundswell can make a river mouth like this a bit tricky, so you need to know what you're doing. But for the experienced crew, that's your window.

Before that, Thursday the 10th and Friday the 11th of September look pretty average. Swell is present (7ft to 12ft) but with cross-shore winds and lumpy conditions, it's not worth the effort for the Rivermouth.

After that main event, Monday the 14th sees the wind go glassy in the morning with a small 5ft swell, which is rideable but very ordinary.

To sum it up: sit tight through a week of choppy, frustrating conditions. The best bet, and the only true standout, is that Saturday the 13th of September if the forecast holds. Get it in the diary.

Rusty.
