The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for Annascaul Rivermouth.
Honestly, it’s a bit of a slow burn for the next week or so. We’ve got some tiny, weak swells and a lot of onshore wind messing things up. The water temp is sitting at 64°, which is a touch warmer than normal for this time of year, so at least it’ll be comfortable while you’re waiting. The first real glimpse of something worthwhile doesn’t show up until the morning of Monday, the 7th of September, when a solid 8ft swell from the west rolls in with a period of 10 seconds. The combined energy is a strong 1313, so there’s plenty of power. The wind is light and cross-shore, which should keep it fairly clean. That morning looks like the pick of the bunch, but it’s a big 8ft, so it’s one for the experienced crew only.
The afternoon of that same Monday, the 7th, cleans right up with offshore wind from the NE and still a chunky 7ft swell. This is the standout window right now. Tuesday morning, the 8th, also looks very promising with a long-period 7ft groundswell from the west at 12 seconds, clean with light cross-offshore breezes. The energy is very strong at 1066. It’s a long-period swell, so it might wrap in a bit straight at a beach, but the Rivermouth can handle that.
After that, the wind chops up again through the middle of the week, but things look to clean up nicely by Thursday the 10th, with NNW cross-offshore winds and a consistent 7ft swell from the WSW (770 combined energy). It’s not the biggest day, but it’s clean and surfable.
The second week is a bit hit and miss with smaller, shorter-period stuff, and by the 11th we’re looking at strong NNW winds again. All in all, circle the 7th through the 10th of September as your best bet, with Monday the 7th morning and Tuesday the 8th morning being the true standouts for the more experienced surfers.
Rusty.
