The Lowdown
Alright, let's get stuck into this. Rusty here, looking at the charts for Portreath Beach.
Honestly, the next week and a half is a bit of a mixed bag. We've got some swell on the way, but the wind is going to be a real pain in the neck for a lot of it. The water temp is sitting about average for the time of year, nothing unusual there.
The best window we're looking at is the morning of Saturday the 5th. That's the standout. The wind is going to be glassy from the ENE, making for some clean conditions. We've got a 4ft swell rolling in from the west with a 10-second period, which is a nice, solid groundswell. The combined energy is moderate at 279. It's a bit of a short window, as the afternoon turns messy with a light cross-onshore, but that morning session is the one to circle on the calendar. Keep in mind, Portreath is a beach break, so a long period swell like this can sometimes be a little straight, but with clean conditions, it'll be worth a look.
Before that, it's pretty grim. The winds are mostly cross or cross-onshore from Tuesday the 1st all the way through Friday the 4th, making for choppy, poor surf. The swell gets bigger, up to 6ft on Wednesday the 2nd, but with a 19 mph cross-wind, it's a mess. Later that same day, the combined swell energy hits 427, which is moderate, but it's wasted on the wind.
After that Saturday gem, it drops off. Sunday the 6th has clean offshore winds from the ESE, but the swell is tiny, only 2ft to 2ft. Not enough to push a paper boat. Then we get a run of poor surf with a mix of onshore winds and bigger, messy swells through the middle of the week.
Looking further out, the 11th of September sees a solid 7ft to 8ft groundswell, but the wind is onshore or cross-onshore. That's a lot of power, with combined energy hitting 1281 on the Friday afternoon, but it's going to be a washing machine. That’s more of a kite-surfing setup than a paddling one.
The real silver lining might be the morning of Sunday the 13th and Monday the 14th. We get clean, cross-offshore winds from the ESE and E, with a 3ft to 4ft westerly swell. The period on the 14th stretches to 12 seconds, which is nice. It’s not going to be big, but it could be clean and fun if you’re happy on a longboard. The combined energy sits around 485, so there's some decent push.
So, to sum it up: the best bet is the morning of Saturday the 5th. The long-range stuff on the 13th and 14th is promising but less certain. The rest of the time, either the wind is howling or the swell is tiny.
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.
