The Lowdown

Alright folks, Rusty here with a look at what we’ve got coming up on the Cornwall coast.

To be honest, the next week and a half is a bit of a write-off for any decent paddling. We’ve got a long dry spell ahead. From now, through the 14th of August and all the way until the 26th, there’s nothing worth getting the boards wet for. The wind is mostly onshore or cross-onshore, and the swell is messy and weak. You’ll see a lot of “poor surf conditions” in the logs, and that’s about the size of it. Don’t even bother before the 26th.

Now, the one window that finally lights up is on Wednesday the 26th of August, down at Portreath Beach. The morning starts to show some life with a clean little 1 ft swell from the WNW, but it’s a bit weak (combined energy of all swells directed here is just 83). The real standout is the Wednesday afternoon. We’re talking about a glassy session. The wind drops to glass, the surface will be like a mirror, and you’re looking at a 4 ft swell from the West. The wave comment says “surfable waves but very ordinary conditions,” but don’t let that fool you—that glassy wind is a major positive. It’ll be clean. The combined energy is moderate at 163, so there’s a bit of push there. The period is only 6 seconds, so it's a short-period wind swell, but with those conditions, it'll be fun on a longboard or a fish. It’s a fairly consistent beach break, and crowds are often, so expect company if it’s a nice day.

Then on Thursday the 27th, we get a proper injection of energy. The morning sees a 5 ft swell from the West with a 9-second period, but the wind is a fresh offshore from the ESE at 19 mph. That’s a big positive—clean, lined-up waves. The combined energy jumps right up to 408 (moderate to strong). That’s a serious amount of juice. However, at 5 ft, it might be starting to push the limits for beginners. The afternoon cleans up even more with a moderate offshore from the SE, 16 mph wind, and a 4 ft swell (combined energy 335). The logs say “expect good surf conditions.” That’s the one to aim for—Thursday afternoon is your best bet in the whole forecast window if you can get on it. The shallow beach breaks might get a bit straight, but with that offshore wind, it should be peaky and fun.

After that, it fades back into junk by Friday the 28th. So mark your calendar for the 26th afternoon and the 27th. The rest of the 16 days is a no-go.

Stay stoked, and don’t force it.
Rusty

Information about the Portreath Beach Surf forecast

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