The Lowdown
Alright folks, Rusty here. Let’s have a look at what the next couple of weeks are shaping up like for Annascaul Rivermouth.
Right off the bat, I gotta be straight with you – it’s a grim start. The first week is pretty much a write-off. We’ve got a proper stormy mess blowing through from the 3rd right through the 9th. Onshore winds are just tearing it up, making everything lumpy and messy. Thursday the 3rd is a total loss with onshore winds and a raw 7ft swell that’s got no shape to it. That energy is there – we’re talking moderate to strong numbers (575 to 672) – but it’s wasted. Friday and Saturday aren’t any better, with tiny, weak swell and cross-onshore winds. There’s a little bump on Sunday the 6th, but again, the wind’s all wrong, and the energy (656) is just making a mess. Monday the 7th is a no-go with a big, unruly 10ft swell and strong winds up to 25 mph. This run of poor conditions lasts right through to the 9th.
Things look like they’re starting to change around Wednesday the 9th, but it’s still nothing to get excited about – just weak and choppy.
Now, there is a light at the end of the tunnel. Thursday the 10th is where it gets interesting. We’ve got a proper pulse of long-period groundswell rolling in, with the combined energy hitting a strong 2384 in the morning. The morning is a bit touchy with onshore wind, but the afternoon is the real deal. The wind swings around to a light cross-offshore breeze from the NNW, cleaning it right up. You’re looking at a solid 10ft of WSW groundswell (period 10 seconds) with clean conditions. That’s the standout session of the whole forecast period.
That quality carries over into Friday the 11th. The swell drops right back to 4ft, but those clean cross-offshore winds are still holding, making for some tidy little waves. Then Saturday the 12th is another beauty. We’ve got a clean 8ft groundswell from the WSW with glassy conditions in the morning – absolutely no wind. That’s prime. The energy’s solid at 866. This spot can get a crowd sometimes, so if you want a quiet one, dawn patrol on Saturday is your move for sure.
After that, the surf tails off into the second week. Sunday the 13th still has some clean 5ft waves in the morning with glassy conditions, but it’s nothing special. The rest of the week drifts into smaller, weaker swells. There’s a bit of a pulse on Monday the 14th with 7ft from the west, but the wind conditions are just okay, nothing to write home about. By Tuesday the 15th and beyond, we’re back to tiny waves and mostly flat days right through to the 18th.
Honestly, with that big, messy early week and a proper clean swell window on the 10th, 11th, and 12th, that’s your only real window. The 10th and 12th are the clear standouts. Don’t bother before that.
Stay stoked,
Rusty

Information about the Annascaul Rivermouth Surf forecast

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.
