The Lowdown
Alright, this is Rusty, and I’ve got the outlook for the Annascaul Rivermouth.
Well, I’ve got to be honest with you – the next couple of weeks are looking pretty grim. We’ve got a 16-day window here, and it’s a total flat spell for the most part. There’s not a single recommendation in the entire forecast. The only break we have data for is Annascaul Rivermouth, and the surf is consistently rated as poor.
Kicking off on Tuesday the 11th of August, we start with a small, weak 3ft swell from the south with a short period of just 5 seconds. The combined energy is low at 100, and with a cross-shore wind, it’s choppy and unrideable. The water temperature is about average for this time of year.
Throughout the rest of the first week, things don't improve. We see some slightly bigger swell—around 5ft from the southwest and west—on Wednesday the 12th, Thursday the 13th, and Friday the 14th. The energy ticks up a bit, getting into the 300s and 400s, but the wind stays cross-on or onshore, creating choppy, messy conditions. From Saturday the 15th onward, the wave heights drop off a cliff, down to 1ft. The wind goes light and even glassy on the Sunday, but with no swell to work with, it’s just flat. You could stand on your board and not move.
Heading into the second week, it’s a blank run. Monday the 17th and Tuesday the 18th see a tiny pulse of 3ft to 4ft west swell, with some clean wind and even glassy conditions, but the energy is still low and the size is tiny. From Wednesday the 19th of August all the way through to Wednesday the 26th of August, the swell is practically non-existent—0.7ft to 2ft from the southwest and west, with very low energy rarely cracking 60. The periods get long, up to 16 seconds, but with no height, that’s just a long-period ripple. The wind is mostly light, and sometimes even offshore, but it doesn’t matter because there’s nothing to ride.
This is one of those stretches where you leave the boards in the car. It’s a tough run for the area, but it happens. Keep an eye on the forecasts a few days out, because things can change, but for now, there’s no point getting worked up.
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.
