The Lowdown
G’day, Rusty here. Look, I’ll level with ya – the next couple of weeks are a tough watch for Annascaul Rivermouth. The forecast is mostly a write-off for decent surf, with a few flickers of hope way down the line. It’s a real test of patience.
The first week and a half is pretty much a dead loss. From Tuesday the 4th right through to the end of the following week, we’re looking at tiny, weak waves and messy wind. Swell heights are mostly well under 3 feet, with combined energy readings barely reaching double digits – a measly 39 at best early on. The wind is a constant problem, swinging from cross-on to onshore, keeping everything choppy and blown out. It’s grim. Honestly, there’s a solid 8–9 day gap where you’d be wasting your time.
The only real glimmer of hope comes on Thursday the 13th of August. The morning session is the standout of the entire 16-day window. Swell picks up to 7 feet from the west, with a 9-second period, and the combined energy jumps to 699 – that’s proper moderate wave energy. The wind goes light and cross-offshore from the north-northwest. That’s the cleanest we’ll see it. The water temp is 63°, which is about a touch warmer than normal for the time of year, so it’s not too bad for a session. The afternoon drops off to 4 feet, but still clean with cross-off wind. The rest of the time? It’s painful. The 12th of August has a 6 feet swell, but the wind is cross-on and the report says “marginal” – so don’t get your hopes up.
Swings and roundabouts, mate. Hang tough, mark that Thursday morning in your calendar, and hope the forecasts shift. This is a sheltered spot, and it’s showing its true colours.

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.
