The Lowdown

Alright folks, Rusty here. Let's have a proper look at what's on offer for Portreath Beach over the next couple of weeks.

Right off the bat, I gotta be straight with you – this is a rough stretch. We’re looking at a long, frustrating gap before anything even remotely rideable shows up. For the first ten days or so, from the end of August through the first week of September, it’s pretty much a write-off. The wind is a mess, mostly screaming onshore or cross-shore, and the swell is either tiny, short-period slop, or when it does get some size, it's blown to bits. The water temp is a touch warmer than normal for this time of year, coming in at about 64°, but you won't be in the water enough to notice.

The real agony starts on the 29th of August with a 12ft swell, but it's blowing a gale from the WNW, making it a total disaster. The swell energy is strong (1852), but it's all for nothing. There's a solid 6ft to 8ft window from the 30th to the 4th of September, but the wind is just never on our side. It’s that classic “so close, yet so far” feeling.

The first real glimmer of hope comes on the 7th of September, Monday afternoon. The forecast is showing an 12ft SW swell with a 8-second period, and the wind and tide look favourable. But the catch is, it's predicted to be too big for this break. That’s expert territory, and even then, it's a gamble. The swell energy is very strong (1489), but for most of us, that’s a day to watch from the car park.

Then, the 9th of September, Wednesday morning, is the one I’d circle on the calendar. The wind is glassy, dead calm from the west, and we’ve got a 6ft swell from the west with a 9-second period. The wave energy is moderate (541), but it’ll be clean. The direction is right on the money for the optimum NW exposure. This is a rare, genuine opportunity for a patient surfer. It’s still a bit of a wait, but that’s the standout.

After that, it’s back to the usual story. The 8th of September has a massive 15ft, 11-second groundswell, but it’s hammered by strong onshore winds. The swell energy is extreme (4640), but it’s a no-go for a paddle. Honestly, that setup might be more interesting for the kite crew than us. The rest of the window is a mix of clean offshore winds on the 10th and 11th, but with tiny swell or a weird long-period (12 seconds) that’s just not going to wrap in properly.

So, to sum it up: the wait is long and painful, but the 9th of September morning is your best bet. Get out there if you can.

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.

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.
