The Lowdown
Right then, let's have a look at what we’ve got for the next couple of weeks here. To be honest, it’s a bit of a lean spell. The swell just isn’t finding the coast with any punch, and for the first few days, you’d be hard pressed to get anything worth paddling out for. There’s a long stretch where the conditions are pretty poor, so don't expect much action until we get into the second week.
It all starts off on Tuesday the 15th with a sloppy 4ft from the WSW at a short, weak 7 seconds – 145 (moderate) in the energy department – but the WNW winds are pushing 15-18 mph onshore, making it choppy and rubbish. That theme pretty much holds through the week. Wednesday the 16th has a bit more knee-high stuff, but the period stretches a touch to 9 seconds, energy bumping to 256 (moderate), but the wind is still messy. Thursday the 17th sees the swell try to push up to 5ft around the 7-second mark, 276 (moderate) energy, but again, the wind is a problem, making it bumpy.
Friday the 18th into Saturday the 19th is more of the same – small, short-period swell, 3-5ft, with onshore winds and energy readings in the 100-176 range (weak to moderate). It’s not doing anything for us.
Finally, there's a little shift on Sunday the 20th morning with a brief window: light WSW winds at 3 mph giving a light cross-onshore, swell dropping to 3ft at 7 seconds, 109 energy. It’s still weak, but at least it’s not howling. Then by Monday the 21st, we hit the smallest stuff – 2ft, 7 seconds, 40 energy – but the morning turns glassy with zero wind. It's tiny, but clean.
The standouts for the whole two weeks are both small and clean, coming later in the second week. The best of it looks like Wednesday morning the 23rd at Aberavon. The swell is a modest 3ft from the WSW at 9 seconds (159 energy, moderate), but we get light offshore winds from the east at 3 mph, giving clean conditions. That’s about as good as it gets right now. On Friday morning the 25th, we get another interesting little window: the swell is only 1ft from the WSW, but the period jumps to a very long 14 seconds with glassy conditions, energy just 51 (weak). That’s a real long-period groundswell, which at a beach/reef setup like Aberavon can look a bit straight, but you might find a little runner if you hunt around. That second one is promising but far off, so keep an eye on it.
It’s not a time to be holding your breath for big waves. We are looking at a proper slow period. The water temp is about average for the time of year – nothing unusual there.

Information about the Aberavon Surf forecast
The above surf forecast table for Aberavon provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Aberavon can be found by selecting the local surf guide option on the grey menu. Our Aberavon surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Aberavon) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
