The Lowdown
Alright folks, Rusty here with a look at the next couple of weeks at Portreath Beach.
Honestly, it’s a pretty bleak picture overall. We’ve got a 16-day window, and for the first three days, there’s nothing doing. The surf is flat and useless through Sunday and Monday. Then we get into a long stretch where the conditions just aren't cooperating. It’s a frustrating run.
The first real chance of anything rideable won’t come until around Wednesday the 12th. That morning the swell is a tiny 3ft from the west, but with clean conditions and a gentle breeze, it's at least a chance to get wet. The real standout moment, if you can call it that, looks to be Wednesday afternoon. The wind goes glassy, flat calm, and the swell ticks up just a touch to 3ft from the west with a moderate wave energy (136). The waves will be surfable, but you’d be lying if you said they were any good. It's the best of a bad lot by a long shot.
Looking further out, the swell does try to pick up a bit around Saturday the 15th, with chest-high 4ft to 4ft sets from the west. However, the wind is a fresh, lumpy cross-onshore, so it’s going to be a mess. By the time we get to Friday the 21st, the swell bumps up to a solid 5ft to 6ft from the north, but again, the wind is on it and choppy. That kind of size with onshore wind just turns the place into a washing machine, maybe more interesting for the kite crew than us paddle surfers. The period on those northerly swells is short and weak too, so the shape will be crap.
The only other small window is the morning of Saturday the 22nd. The swell drops back to 3ft from the north, but we finally get some clean cross-offshore winds from the south. It’s the last flicker of hope, but with the long gap before it and how inconsistent the whole run has been, it's a long shot.
To be honest, this is a tough one. Portreath is fairly consistent, so a blank run like this is unusual. The forecasts can always change for the better, but right now? Pack a book.
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.
