The Lowdown
Howdy, Rusty here. Let’s talk surf, but I’ll switch to feet, knots, and Fahrenheit for ya.
The first five days, from Wednesday the 19th through Monday the 24th of August, are pretty grim at Annascaul Rivermouth (Ireland) . Tiny, lumpy, and cross-shore winds—keep the board in the car.
The one real highlight is Tuesday morning the 25th of August. We finally get some proper swell: 6 ft out of the WSW with a 9-second interval, and the wind goes glassy—dead calm. That means clean, pushy waves with moderate energy (633). Water temp is a balmy 65°F, which is about 4°F warmer than normal for this time of year—very noticeable. For intermediates, this is the session to aim for. Crowds are possible, so don’t sleep in.
Tuesday afternoon holds with 6 ft from the WSW and a light offshore breeze, still clean. After that, the wind turns westerly and messy again through the end of August. There’s a long-shot window on Wednesday morning the 2nd of September with 6 ft from the W and a light offshore, but it’s two weeks out and the pattern is shaky.
Bottom line: Tuesday the 25th is your best bet. Everything else is either flat or blown to bits.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
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.
