The Lowdown

Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.

Honestly, it's a tough stretch for Porth Ceriad. We're looking at a long, quiet spell with barely a ripple for days. The first record kicks off on Wednesday the 29th of July with a tiny 2ft SW windswell carrying a weak energy reading of just 14, and the wind is howling 12 mph onshore, making a proper mess of things. The water temp is about what you'd expect for this time of year, so no surprises there, but the lack of any real push is the story.

There's a gap of low-quality surf stretching right through until at least the 13th of August. The swell heights are almost entirely below 2ft, with energy readings barely creeping into double digits. You'll see some glassy mornings, like Friday the 31st of July and Sunday the 9th of August, but with only 1.3ft and 0.3ft of swell respectively, there's just nothing to ride. The odd offshore wind pops up on the 5th and 6th of August, but again, the swell is a measly 0.3ft.

The pick of a very poor bunch, if you're desperate, might be the morning of Friday the 31st of July. It's glassy with a 1.3ft NW swell, but at under 8 seconds period, it's weak and won't offer much shape. For a beginner, the tiny size is safe, but the lack of power makes it frustrating. On the 5th and 6th of August, we see some longer period 13-second groundswell coming from the W, but only at 0.3ft. It's clean and offshore, but that's a bathtub scenario, not a surf. For the whole period, the combined energy is low, barely ever cracking 14. This is a classic flat spell for the area; it doesn't stay this way forever, but right now, there’s nothing worth waxing up for.

Stay tuned, forecasts can change, but for now, I'd leave the board in the shed.

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.
