The Lowdown
Alright, Rusty here again, looking at the same stretch for Annascaul Rivermouth, but in feet and degrees Fahrenheit. No sugar-coating it – this is a grim 16 days for surf. There’s nothing I’d call a good session anywhere in the window.
The run starts poor. Saturday, August 8th, has a small 3-foot swell from the SSW, but the wind is cross-on and choppy, with weak energy. Sunday the 9th is practically flat. Monday the 10th goes dead calm and glassy, but the swell is a tiny 3 feet from the West, with barely any energy. It’s pretty, but unsurfable.
Mid-week, Wednesday the 12th, we get a little more size – 5 feet from the WSW and moderate energy (360) – but the wind is onshore or cross-on, keeping it poor. Thursday the 13th has a 5-foot West swell with moderate energy (514), but the wind is light cross-on, and the conditions are only “marginal.” Not exactly a standout.
The worst of it comes Friday, August 21st. A massive 8-foot swell from the West rolls in, packing very strong energy (1025), but it’s a cross-onshore, choppy, wind-blown disaster. That’s a kite surfer’s dream, not a paddler’s. The final day, Sunday the 23rd, is glassy, but it’s only 1 feet of long-period, high-period swell – clean, but totally gutless.
For a sheltered spot that’s usually very consistent, this is a long, dry spell. It’s not normal for the area to go this flat and messy. Keep your gear in the car, but don’t get your hopes up. Forecasts can change, but right now, there’s nothing to chase.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
