The Lowdown
Right, let’s have a look at the next couple of weeks for Aberavon. To be straight with you, it’s a bit of a grim stretch for the paddle crew. The forecast is showing plenty of swell at times, but the wind gods are just not playing ball, and we’re going to be dealing with a lot of onshore and cross-onshore slop.
The water is sitting at 69°F, which is a massive 8°F warmer than usual for this time of year. That’s a seriously odd anomaly, the kind of thing that gets you thinking about how strange this season has been.
Alright, so the outlook starts on Monday the 31st of August. There’s some decent energy in the water, with a combined swell energy of 461, and waves around 5ft from the WSW. But a fresh cross-shore WNW breeze is just going to chop it all up. It’s going to look a mess. That wind kicks in all day and it’s not worth your time.
Tuesday the 1st drops right off. The swell energy collapses to 54, and the waves shrink to 2ft. The wind swings more onshore, so it’s small and junky. Not good.
We’ve got a run of poor conditions right through to the 7th of September. The swell pulses a bit, there’s a moderate energy day on the 4th with around 6ft to 6ft, but the wind is fresh and cross-onshore again. It’s all lumpy and bumpy. There’s really nothing to get excited about here.
Finally, we get a bit of a reprieve on Tuesday the 8th of September. The morning is the best of the whole run, with a light variable wind, 3ft of WSW swell, and a period of 11 seconds. The combined energy is 229. It’s still not perfect, and the wind is a touch onshore, but it’s the only window that’s not blown out. It’s marginal at best, but it’s the standout simply because it’s the least bad.
After that, it’s rubbish again. A couple of clean, cross-offshore days on the 11th and 12th have no swell at all, just 1ft. You could surf a foamie if you were desperate, but there’s no push.
The final pulse comes on the 14th and 15th of September. Monday the 14th has a moderate 4ft of swell with a combined energy of 318, but it’s cross-onshore and bumpy. Then Tuesday the 15th sees a real increase in size, hitting over 7ft in the morning and 8ft by the afternoon, with a combined energy of 878. That’s some proper power, but the wind is going to be howling onshore at up to 28 mph. That’s not surfable in a traditional sense; that’s a full-on washing machine. With that much swell and that much wind right on it, this setup is going to be way more interesting for the kite crew than for us. It’s a tough one, lads. The best window is that Tuesday morning on the 8th, and even that’s a bit of a gamble. Hang in there.

Further information to help with frequently asked questions about our surf forecast for Aberavon 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.
