The Lowdown

Alright folks, Rusty here with a look at what's coming our way for the Annascaul Rivermouth stretch. Gotta be straight with you – it’s a tough run ahead. The water is sitting at a balmy 64°, which is much warmer than normal for this time of year, so at least you won't be freezing while you're staring at it.

We kick things off on Friday the 28th with next to nothing. You’re looking at a tiny 0.7 ft south swell with weak energy (3) and a cross-on breeze. It’s a non-starter. Saturday the 29th shows a tiny bump in the morning, then a slight lift to 3 ft from the SW by afternoon, but the wind is cross-onshore and it's messy with moderate energy (168) at best. It’s still a no-go.

Now, Sunday the 30th morning brings a pulse of 6 ft from the WSW with a solid jump in energy (606) and light offshore winds. That might sound promising, but the report calls it poor. The wind’s off the land for a moment, but the conditions are just not coming together. That size is getting too big for beginners, but the quality isn't there for the experienced crew either. This pattern of poor surf sticks with us for days.

From here we hit a real dry spell. Monday the 31st through to around the 8th of September we’ve got waves on offer – sizes ranging from 5 ft up to a hefty 12 ft – but every single one is tagged with "poor surf conditions." The winds are consistently cross-onshore or onshore, often fresh to strong, making a lumpy, choppy mess. The energy gets strong, hitting 1582 on the 7th, but with a fresh cross-onshore wind and a short period, it’s just a washing machine. That big 8 ft on Thursday the 3rd is powerful (1250) but the wind’s ruining it. Honestly, with these winds and beach setup, it looks more interesting for the kite surfers than us paddle guys right now. There's a total lack of quality here for about 10 days.

Finally, there's a little glimmer on Thursday the 10th of September. The morning brings a clean-ish 4 ft from the SW with cross-offshore winds. The energy is moderate (260). It’s described as "surfable waves but very ordinary conditions." That’s the best we get. It’s not a standout by any stretch. The afternoon gets a bigger 6 ft from the SW with a longer 10-second period and light winds, but it’s called "marginal." That Thursday morning window is the only time I’d even bother looking at the ocean, and even then, keep your expectations on the floor.

The rest of the run into the 12th is blown out again. There’s nothing in this 16-day window that’s worth calling a winner. Just a whole lot of waiting.

Rusty.

A general guide to surfing at Annascaul Rivermouth can be found by selecting the local surf guide option on the grey menu.

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.
