The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks at Portreath Beach.
To be straight with you, the first week is a proper battle. We’ve got a long stretch of nothing special from the 7th of August right through to the 11th. The swell is tiny, mostly around 1ft to 1ft, with a weak combined energy (22 to 52). The wind is all over the place, mostly onshore or cross-onshore, and the surf is just poor. It’s a blank run, and for this area, that’s how it can be sometimes.
Things finally start to show a pulse on the morning of the 12th of August. The swell pushes up to 3ft from the west, with a period of 10 seconds and a moderate combined energy of 155. The wind is light and cross-offshore, cleaning the faces up. It’s surfable, but very ordinary – a small, grovelly option for the keen ones.
The real standout, and the one to circle on the calendar, is the afternoon of Friday the 21st of August. The swell is a solid 12ft from the WSW, with a period of 9 seconds and a massive combined energy of 2805. The wind is a strong cross-offshore breeze, keeping it clean. Now, this is a big one. At 12ft, this is strictly for experts only. The swell is huge, and the break will be absolutely pumping with raw power. The wind and tide are favorable, but you need to know what you’re doing out there. This is the best on offer, and it’s a proper big-wave session.
Before that, the morning of the 21st is also big with 12ft swell, but the wind is a messy cross-shore at 25 mph, so it’s all over the place. The 22nd of August sees the swell dropping back to 6ft, but the wind is a strong cross-onshore, making it messy again.
So, for the whole period, the only true standout is that Friday afternoon on the 21st. The rest is a waiting game, but that one session looks like it could be a belter for the experienced crew.
Stay safe, and keep an eye on the horizon.
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.
