The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s on the menu for Porth Ceriad over the next couple of weeks.

Honestly, it’s a pretty bleak picture for the near future. The whole 16-day window is a struggle, with a massive gap of very poor conditions right at the start. For the first week, we’re looking at almost nothing. There are a few tiny pulses of energy, but the winds are all over the place—cross-on, onshore, lumpy, choppy. It’s a write-off for paddle surfing. The only real standout comes much later, and it’s a long shot.

The best of a bad bunch shows up on the morning of Saturday, August 15th. We’ve got a glassy start with a 4ft swell from the west, period around 5 seconds. The combined energy is weak (68), so it’s not going to have much push, but that clean, glassy surface will make it look a lot better than anything else on offer. It’s a beginner-friendly break, so the small size is actually perfect for learning. The water is a touch warmer than normal for this time of year, which is a small bonus.

Before that, the morning of Saturday, August 8th offers a tiny glimmer. A 4ft WSW swell with a light offshore NNW wind at 10 km/h. The wave energy is still modest (74), and the period is short, so it’ll be a bit crumbly, but it’s the only clean, offshore window in the whole first week. It’s surfable, but nothing to write home about.

After that, it's back to the doldrums. The morning of Friday, August 14th is glassy with a 2ft SW swell, but again, it’s just small and weak (48). It’s a beginner’s day, but don’t expect much.

Overall, the surf is poor for the majority of this forecast. The only real window to get excited about is that glassy Saturday the 15th. Keep an eye on it, but don’t hold your breath for anything epic.

Information about the Porth Ceriad Surf forecast

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