The Lowdown

Righto, let’s have a look at what’s on offer here. We're at Annascaul Rivermouth. This spot is very consistent, but unfortunately, we’re in for a long, frustrating wait before anything worthwhile shows up.

The immediate outlook is grim. From Monday the 10th through to the end of Thursday the 14th, the surf is either tiny, onshore, or just plain messy. The combined swell energy is weak to moderate at best (82 to 229), with short-period, weak windswell. Not worth paddling out for.

Friday the 14th afternoon finally sees a tiny flicker of hope. It’s still small at 4ft from the WNW with a short 8-second period, but the wind goes cross-offshore and it cleans up. The wave comment says it's surfable but very ordinary – and I’d agree. It’s the first real chance to get wet, but don’t expect much.

Then we hit a massive gap. The weekend of the 15th and 16th is almost flat. Swell drops to 0.3ft to 1ft. Sunday morning goes glassy but there’s nothing to ride.

Monday the 17th sees a pulse of 7ft from the west with 8 seconds, but it’s onshore wind and the conditions are marginal. The energy bumps up to 636 (moderate to strong) but it’s not clean. The whole week after that is a write-off until we get to the real standout.

Now, here's the one you’ve been waiting for. Wednesday morning the 19th of August. This is your best bet by a long shot. The swell jumps to 8ft from the WNW with a 10-second period, combined energy cranks up to 1246 (strong to very strong). And the wind? Glassy. Utterly glassy. The file says "expect very good surf conditions" – that’s the one. This is the standout. The water temp is about average for the time of year. The swell is over 8ft though, so it’s going to be a big day – only for experienced surfers. The direction (WNW) isn’t a perfect match for the optimum of SW, but with that power and zero wind, it’ll still hold up.

After that, the last few days of the window (20th to 25th) are clean but small again – 2ft to 3ft mostly, with offshore winds. The 24th of August morning has another decent push: 8ft from the SW, light offshore wind, and good conditions expected (score 2). That’s a solid secondary option, especially for a lighter crowd, as it’s not the main event.

Honestly, the long wait is painful, but the morning of the 19th and the 24th make it worth hanging in there. Don’t bother before that unless you’re desperate.

Further information to help with frequently asked questions about our surf forecast for Annascaul Rivermouth may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
