The Lowdown
Alright, Rusty here, let’s have a look at what’s cooking for the next couple of weeks.
First up, it’s been a rough stretch. Portreath Beach has been getting hammered by messy wind and lumpy, blown-out conditions, and there’s hardly anything worth paddling out for. The good news is, after a long gap of poor surf, we finally see a glimmer of hope towards the end of the run.
The water temp is sitting around 64°, which is about normal for this time of year, so you won’t need a thick suit just yet.
The only real standout in this whole forecast is Portreath Beach on Monday morning, the 7th of September. We’ve got a clean, cross-off breeze from the SSW at just 9 mph, and a 7ft groundswell rolling in from the west with an 8-second period. It’s a fairly consistent break, but because it’s a beach setup and the swell has a short period, it won’t be too sorted. The combined energy is solid at 665 (moderate to strong), so there’s some punch, but the crowd factor says “often” busy – expect company. This is the only session with “good surf conditions” flagged, and it’s for intermediate surfers.
Now, a heads-up: the Saturday morning before that (5th September) shows a 8ft west swell with some clean cross-off wind, but it’s scored as marginal – likely a tide issue, so not a full green light. Worth a look, but don’t bank on it.
After that Monday morning window, the wind picks up again hard from the southwest, and we’re back to messy, lumpy, onshore slop. The only other time that’s remotely interesting is Tuesday afternoon the 8th, with a 5ft west swell at 10 seconds and almost no wind, but again, it’s scored as marginal, so treat it as a gamble.
Bottom line: if you’re after something clean, lock in the morning of Monday the 7th of September. After that, we’re back to a long stretch of junk until the forecast runs out.
Stay tuned, forecasts can change – but for now, that’s your best bet.

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.
Portreath Beach is 5 km (3 miles) from Camborne. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Camborne. Camborne has rooms for a wide range of budgets as well as car hire and transport links.
