The Lowdown
Alright, let’s be straight with you. I’ve looked at the next 16 days for Aberaeron, and I’m not gonna sugarcoat it – this is a tough stretch. The truth is, the vast majority of this period is a flat, messy, or wind-blown bust. There’s a massive gap of days with no real surf on offer. From now, right through until the end of the month, it’s all weak, short-period windswell with poor conditions. You’d be wasting your time paddling out. The water is currently sitting at 68°F which is much warmer than normal for this time of year, a real anomaly of 7°F, but it’s not going to help you catch a wave.
The first real glimmer of hope doesn't show up until the morning of Thursday the 29th of August. Even then, it’s not a classic. We get a small 3ft swell from the WSW with a period of 8 seconds, pushing a combined energy of 115 (moderate). The wind is glassy from the SSE, which is the main selling point – it’ll be clean. It’s surfable, but very ordinary. The swell is small and the period is short, so it’s not going to have much grunt. This is a break that’s inconsistent at the best of times, and this is far from the best of times.
Then look at the 3rd of September, Thursday morning. A 5ft swell from the NNW with a period of just 6 seconds, combined energy of 167 (still moderate). The wind is light and cross-off from the ENE, keeping it clean. The size is there, but that short, windswelly period means it’ll be a bit of a bumpy, shifty affair. It’s not a standout, but it’s the only other window with a pulse and clean enough conditions for a paddle.
Overall, the best bet is that Thursday morning, the 29th of August. It’s the cleanest of a very poor bunch. Don’t get your hopes up. The rest of the forecast is a write-off.

Information about the Aberaeron Surf forecast
The above surf forecast table for Aberaeron provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Aberaeron can be found by selecting the local surf guide option on the grey menu. Our Aberaeron 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 (Aberaeron) 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 Aberaeron 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.
