The Lowdown
G’day, Rusty here. Right, let’s be straight with you – this is one of those outlooks where you might wanna hang the boards up for a bit and catch up on some waxing. The whole 16-day window is a write-off for decent waves. There’s not a single recommendation in the mix that’s worth paddling out for, so we’re looking at a blank run from now through to the 12th of September.
Annascaul Rivermouth is the only spot on the cards, and it’s a sheltered setup that needs the right angle to work. The next couple of days are a non-starter. We’re looking at tiny 0.7ft to 2ft slop on Friday the 28th and Saturday the 29th – the swell energy is barely a whisper (3 to 51). Wind is mostly cross or onshore junk, so the surface will be messy. Saturday morning has some clean conditions with a gentle cross-offshore NNW breeze, but with only 2ft of weak SSW swell, it’s not worth the rubber.
Things get bigger from Sunday the 30th – we’re talking 7ft to 8ft on Sunday and Monday, but it’s all poor quality. The wind is hammering onshore, and the combined swell energy jumps up to moderate (321–969), but the whole setup is choppy, blown out, and ugly. It’s the kind of energy that would look more interesting for kite surfing than a proper paddle session. The water temp is about average for late August, so nothing wild on that front.
Into early September, we see a surge of bigger swell – 8ft on Thursday the 3rd with a strong wave energy of 1388, and then 10ft on Thursday afternoon with a long-period 13-second groundswell pushing energy to 3246. That’s a significant amount of power, but the wind is onshore and cross-onshore, ruining any shape. For a break that needs a clean SW swell direction, this WSW/WNW energy with strong onshore wind is a total mismatch. That 10ft swell is big enough for experts only, but with poor conditions, it’s not even that.
The second week stays stubbornly flat or onshore. From the 4th of September onward, it’s a graveyard of tiny 0.7ft to 2ft swells, with a few clean offshore days on the 6th, 7th, and 8th under NNE/ NNW breezes, but swell heights are pathetic (0.7ft to 2ft) and energy is low (17 to 66). The 8th of September morning even goes glassy with a slight SSE breeze, but with only 1ft of WSW swell (13 energy), it’s a flat calm. Then on Wednesday the 9th, a big ugly spike hits: 15ft to 12ft of WSW swell with fresh to strong onshore winds screaming at 18–25 mph, making for a total ocean mess – blown out, dangerous even for experts.
From the 10th to the 12th, the wind stays angry (near gale force on the 10th) and the surf is messy, cross-onshore, and lifeless. No standout days, no hidden gems. This spot is very consistent, but consistently poor for this entire stretch. It’s a dry spell, plain and simple. Forecasts can turn, but right now, save the petrol.
Rusty.

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.
