The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s coming up for Portreath Beach.
Right off the bat, it’s a tough start. The next week and a half is a write-off. We’re talking from Monday morning all the way through to Saturday the 15th – over a week of poor conditions. The swell is there, but it’s messed up by wind and chop, never really lining up. A couple of mornings around the 3rd and 4th have some small, clean-ish waves, but with all that energy being so weak and the wind turning, it’s just not worth paddling out. The water is sitting at 65°F, which is a touch warmer than normal for this time of year, so at least it’s not a cold wait.
Now, the light at the end of the tunnel. The one standout here is Sunday the 16th of August. That morning is the real deal. We’ve got a solid 8ft swell rolling in from the WNW, and the wind is blowing from the SE at a gentle 9 mph, which is offshore. That’s going to clean things up beautifully. The combined energy is pumping at 908, which is strong, and the waves are going to be packing some punch. It’s a big one, though – over 8ft, so this is strictly for the experienced crew. Beginners, stay on the sand for this one.
That swell carries into Monday the 17th, dropping to 7ft in the morning and 6ft in the afternoon, still with clean cross-offshore winds from the east. It’s a step down in energy (492 and 280), but still a solid day of surfing. After that, things drop off again into Tuesday the 18th with tiny, onshore junk.
So, if you’ve got patience, hold out for that Sunday the 16th. That’s the best on offer, and it looks like a good one. Keep your fingers crossed the forecasts hold.

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.
