Alright, let’s get into it. Honestly, it’s a bit of a tough stretch ahead for Portreath Beach. We’re kicking off with a pretty flat, wind-battered run of days, so don’t bother paddling out just yet.
Over the first week, from Monday the 6th right through to about Wednesday the 15th, there is zero surf worth your time. The swell is tiny—mostly under 3 feet—and the wind is persistently cross-onshore or onshore out of the north-west. The water temp is sitting around 60°, which is about normal for the time of year, but you really aren’t missing anything. Wave energy is at a paltry level (anything from 49 to 167 units), and periods are short, meaning no grunt whatsoever.
Thursday the 16th brings a little flicker of hope in the morning. A clean, light east-southeast offshore breeze lines up with a small 4-foot swell out of the southwest, wave energy at 130 (moderate). The period is short—only 6 seconds—so it’ll be a bit crumbly at the beach, but it’s surfable. That’s your only real window for the first ten days.
Friday the 17th through to the weekend gets messy again. We see the swell building—by Saturday the 18th we’re looking at 7 feet from the west-southwest, with wave energy climbing to 602 (strong), but the wind turns onshore from the north-northwest. That’s big, windy, lumpy surf. Only for experts if you’re keen, and honestly, the conditions look more like a kite session than a clean paddle wave. The period is still a short 8 seconds, so it’s all closeout and chop.
Now, here’s the long-range standout: Monday the 20th and Tuesday the 21st. We get a solid 8-foot west swell rolling in, with wave energy hitting 798 to 1156—very strong. The mornings show cross-off winds from the east-southeast and east, which means clean conditions at times. The swell period ticks up to 9 seconds, which is a bit more juice, but it’s not a long period groundswell, so expect a mix of bowl and line. This is expert-level size, but if you’re a strong surfer, these two days could offer the best of the whole outlook. The crowd situation at Portreath is marked as “often” busy, so expect company, especially with a clean, 8-foot day.
To sum up: the first week and a half is a write-off. Thursday the 16th morning gives you one small, clean session. Your real standout is the swell on Monday 20th and Tuesday 21st—big, powerful, and cleaner winds. That’s the time to point your car at the beach if you’ve got the skill for it.

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.
