The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming our way for Portreath Beach over the next couple of weeks. I’ve got to be straight with you—it’s a tough stretch ahead. We’ve got a whole lot of nothing for the first week, and then a few flickers of hope late in the game, but nothing that’s going to have you racing for the car keys.

Right now, there’s no surf worth paddling out for. The next week is pretty much a write-off. From the 13th right through to the 20th, we’ve got a messy combination of onshore winds and choppy conditions. The swell is there, around 5ft to 8ft, with moderate energy (in the 400s to 900s), but the wind is all wrong—cross or cross-onshore, and strong. You’ll be fighting a losing battle. On the 15th and 16th we see a bit of a bump with 6ft to 6ft from the WNW, but it’s a short-period windswell (8 to 11 seconds), so it’s going to be lumpy and close out. On the 18th we actually get some long-period groundswell creeping in—13 seconds from the WNW, and the combined energy jumps to 1444, but the winds are cross-onshore and choppy. It’s a "marginal" call at best. Honestly, this setup looks more interesting for kite surfing than paddle surfing.

Then from the 19th and 20th, it fades. We’re down to 5ft to 3ft, and the wind stays cross-onshore. The swell period drops right off on the 19th (7 seconds). Not worth it.

We hit a real quiet patch from around the 21st onward. The swell drops off to under 3ft, and while the wind turns more offshore or cross-offshore, the energy is low (56 to 376). There’s a moment on the 21st morning where things look clean—light offshore from the SSW, 3ft from the WNW, 13-second period, and the energy is still moderate at 376. It’s the one standout of the whole run. That’s your best bet. Water temp is a touch warmer than normal at 64°F, about 3°F above average, so it’s a bit on the mild side for this time of year. The crowds at Portreath can be an issue—this is a spot that’s often busy, so if you do get out there on that Monday morning, expect company.

After that, the swell just dies. From the 24th to the 28th, we’re looking at 3ft down to 1ft, with periods around 8 to 13 seconds but combined energy dropping below 100. It’s clean, but there’s simply no wave. You’ll be floating.

So, in short: the first week is a washout. The only real chance you’ve got is Monday the 21st morning, and even then it’s small. After that, it’s a flat spell all the way to the end of the month.

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.
