Annascaul Rivermouth Surf Forecast and Surf Report

G'day, I'm Rusty, and I've got the full rundown on what's coming our way at Annascaul Rivermouth.

Right off the bat, I'll be straight with you: this is a tough stretch. The water's sitting at a noticeably warm 65°, which is about 4° warmer than average for this time of year, so it's a touch warmer than normal. But the surf? It's a long, dry spell with very little to get excited about.

We've got a whole lot of days here with low scores, and the first real glimmer of something surfable doesn't pop up until the very end of the first week. The pattern is a lot of weak, short-period windswell with poor onshore or cross-shore winds, so it's just messy and small. The combined swell energy is weak for most of it, with values barely cracking 100 (like 82, 56, 79) until a few pulses in the middle of the month.

Let's break it down day by day. Monday the 10th kicks off with a tiny 3ft W swell at 8 seconds, but it's cross-off in the morning and cross in the afternoon, so it's just poor. Tuesday the 11th has a bit more energy in the afternoon with a 3ft WSW swell hitting 318, but it's cross-on and choppy. Wednesday the 12th sees a modest bump to 4ft and 5ft WSW swell, with the combined energy climbing to 328 and 447, but again, it's cross-on and the quality is described as marginal at best. Thursday the 13th and Friday the 14th are both around 4ft to 6ft W swell, but they're all cross-shore or onshore, with the energy staying moderate in the 200-400 range. Not a single standout.

Then we get a real drop-off. Saturday the 15th and Sunday the 16th have almost nothing – swell drops to 0.3ft and 0.7ft. The only positive is a glassy moment on Sunday afternoon with a 1ft WSW swell, but that's far too small to ride. There's a gap of several days with no real surf.

Now, heading into the second week, things do start to look a little better. Monday the 17th has a 3ft WSW swell under offshore ENE wind, giving clean conditions. The combined energy is still weak at 99, but it's a start. Tuesday the 18th and Wednesday the 19th have a 4ft to 4ft W swell with clean offshore or cross-off winds, and the energy climbs to 241 and 255. Still nothing to write home about, but it's surfable.

The best of the bunch comes on Thursday the 20th of August. The morning sees a 4ft W swell at 10 seconds with a solid NNE offshore breeze at 12 mph, giving a moderate offshore wind and clean conditions. The combined energy hits 373. It's not a big swell, but it's the most consistent and cleanest window we've got. The afternoon is a bit stronger with the wind, but still clean. After that, things fade again. The 21st has a tiny 0.7ft SSW swell with a long 13-second period, but it's too small.

So, honestly, this is a tough outlook. The best bet is Thursday morning the 20th, but even then it's very ordinary. The rest of the period is a mix of small, weak, and messy surf. Keep your expectations low, lads.
