The Lowdown
Alright folks, Rusty here. Let’s take a good, hard look at what’s coming for Annascaul Rivermouth. Straight up, I gotta be honest with you – the next couple of weeks are looking pretty grim. We’ve got a long, dry spell ahead with barely a ripple to get excited about. The water is sitting at a warm 65°, which is much warmer than normal for this time of year, so at least a dip won’t be a shock to the system.
We kick off Monday the 20th with a tiny 2ft swell from the west, and it’s a long period 11 seconds. That’s a groundswell, but with the combined energy only at 84, it’s weak. The wind is offshore from the NNE, so the surface will be clean, but the swell is just too small to do anything with. The forecast calls it “poor surf conditions,” and I’m inclined to agree. This flat, weak pattern just drags on through the rest of the week. Tuesday the 21st and Wednesday the 22nd are the same story – ankle-snappers at best, with the swell dropping to 1ft and energy down in the 30s and 40s. The wind stays offshore, so the water will look nice, but it’s a lake, not a wave.
Thursday the 23rd, the swell drops even further to 1ft, and by Friday the 24th, we’re down to barely a wobble at 0.3ft with a 13-second period, but the combined energy is just 12. It’s crossed up, and the wind starts to get messy. This is essentially a flat spell. There’s a gap of several days here – from the 22nd right through to the very end of July – where there is absolutely nothing to recommend. The swell is almost non-existent, with energy scores in the single digits for many of those sessions. The wind swings around, even going onshore from the west on the 25th, and it’s just choppy, blown-out junk.
We finally see a tiny pulse of west swell trying to push through on Friday the 31st of July. The morning has a 1ft swell with a cross-onshore wind, so that’s messy. The afternoon looks slightly better, with a 2ft west swell and a 11-second period, and the energy bumps up to 63. The wind goes cross-shore, so it might clean up a little, but it’s still a very small wave. Saturday the 1st of August brings a similar story: 2ft west swell, but the wind is right onshore from the SW. That’s a recipe for a bumpy, close-out mess. The energy is moderate at 89, but the wind is just killing it.
A real standout might appear on the 4th of August. Tuesday morning shows a 3ft west swell with a short 7-second period. The combined energy is 118, which is a moderate, solid push. The wind is light and offshore from the north, so it’ll be glassy. This is the best window in the entire 16-day forecast. The size is still small, but it’s the biggest we’ll see, and the clean conditions will make it rideable for an intermediate. It’s more than a week away, so keep an eye on it, but don’t hold your breath. The short period (7 seconds) means it’s a wind swell, not a groundswell, so it’ll be a bit crumbly and won’t have the punch of a bigger, longer-period swell.
Bottom line: The first week is a total write-off. The second week offers a few more pulses, with the best chance of a ride being on the 4th of August. It’s a long way out, so don’t get your hopes up too high, but it’s the only glimmer of light in an otherwise dark forecast.

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.
