The Lowdown
Alright folks, Rusty here, and I've gotta give it to you straight about Aberavon. This 16-day run is a real tough one to call. There's nothing in the shop window that I'd even call a "decent" option. The first real chance of anything happens... well, you'll see. It's a long stretch.
The water's already weird, sitting at a very warm 66°, which is about 6° warmer than normal for the time of year. That's a real anomaly.
The first week, from Saturday the 12th right through to Friday the 18th, is a total loss. Onshore wind, mostly from the SW or WNW, has got the surface all hacked up. We get a few pulses, like a 5ft swell from the WSW on Saturday afternoon with a combined energy of 237 (moderate), but it's pinned by that 19 mph onshore wind. It's just rough and ugly. The pattern repeats, day in, day out.
Into the second week, and it doesn't improve. Saturday the 19th is more onshore, messy stuff with 4ft swell. Then on Sunday the 20th, the swell jumps up to 8ft from the WSW with a strong combined energy of 746. But with a 19 mph onshore wind, it's a full-on mess. That's a kite-surfing setup, not one for a paddle board.
From Monday the 21st onward, the size just drops through the floor. We're looking at tiny 1ft to 2ft leftovers. There's a couple of clean moments, like Wednesday the 23rd afternoon with glassy conditions, and Thursday the 24th and Friday the 25th with clean offshore winds from the ESE. But the swell is just too small. Even with an 11-second period groundswell on the 25th and clean conditions, the combined energy is only 23; there's zero grunt.
So here's the bottom line: this 16-day stretch is a complete blank for Aberavon. No standout days. You're looking at a week of garbage, then a few days of tiny, clean waves for a longboard if you're really keen, but nothing with any push. It's a quiet period, but that's how it goes sometimes. Don't bin your board though, the forecasts could flip.

A general guide to surfing at Aberavon can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
