The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
First up, don't get too excited just yet. The whole 16-day window is a bit of a struggle, to be honest. The bulk of the period is a write-off, with a long gap from the start right through to the tail end of the second week. The first decent window we see is on the morning of Saturday, September 6th, but it's small. We're looking at a 3ft, 9-second swell from the west, with a clean offshore breeze, giving you maybe a few little ones. The combined energy is weak (103). It's a salvage operation, not a stand-out.
Things get more interesting, but not in a good way, from Sunday, September 7th through to Tuesday, September 15th. We get a lot of swell, with heights pushing 8ft at times, but the wind is just shocking. It's cross-onshore or onshore nearly the whole time, making it choppy and lumpy. That 7ft, 13-second groundswell from the west on Monday, September 7th morning has a massive combined energy of 1607, but it's completely blown out. The setup looks more interesting for kite surfing than paddle surfing, honestly.
Finally, we get a bit of a clean-up on Thursday, September 17th. The wind finally swings offshore and cross-offshore, cleaning things right up. The swell is small, 4ft at 10 seconds from the west (energy 225), but it's a surfable wave. The best of the best, if you can call it that, is on Thursday, September 17th morning at Portreath Beach. It's a small, clean wave with glassy conditions. The water is about 64°, which is a touch warmer than normal for this time of year. It's a rare moment of calm in a very windy outlook. The crowds are listed as "often" here, so expect a few others with the same idea. It's a fairly consistent spot, and on a 4ft, 10-second west swell with a light offshore ESE wind, it'll be the pick of the bunch.
The rest of the 16-day window is just noise. A few small days with clean conditions on the 18th and 19th, but the swell is too short-period (6 seconds) to offer much, and the wind is on the stronger side again. The 19th has a 3ft, 6-second swell from the WNW with a strong cross-offshore wind, which is just a messy, bumpy afternoon.
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.
