The Lowdown
Alright folks, it's Rusty here. Right off the bat, I gotta tell you, this is one of those outlooks where you might want to leave the boards in the van for a good stretch. The entire 16-day window for Portreath Beach is a tough read, with zero standout surf days. It's a proper flat spell to start, and even when the swell tries to show up later, the wind just ruins it.
Straight up, there is nothing worth paddling out for on Thursday the 16th. The swell is a tiny 1.0ft with weak energy (22) and onshore winds. That theme carries right through the week. Friday the 17th and Saturday the 18th are a no-go with bumpy, choppy conditions and minimal swell. We've got a long gap here with absolutely nothing to recommend.
We finally see the combined swell energy climb into the moderate range on Saturday the 25th of July, hitting 158, but the swell height is only 4ft and it's a short-period 6-second windswell with onshore winds. It's rough and lumpy, not for surfing. The onshore winds just won't let up. By the 30th of July, the afternoon sees a spike in energy to 292 with a 5ft short-period swell, but it's lumpy and cross-onshore. Even the later days around the 31st of July show some moderate energy (218), but again the winds are onshore and messy.
The water temp on the 16th is sitting at 63°, which is a touch warmer than normal for this time of year, so at least the water feels nice if you want a swim.
But honestly, for paddle surfing, Portreath Beach is not the spot in this whole window. The setup is a beach break, and with the persistent onshore wind and short-period swell, this looks way more interesting for kite surfing than for us regular surfers. The forecasts can always change, but as it stands, it's a long wait.
Stay patient.
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.
