The Lowdown
Alright, Rusty here. Let's have a look at what's on the menu for the next couple of weeks.
Honestly, it's a bit of a rough patch. The entire 16-day window is looking pretty flat and grim for any kind of decent surf. The models are showing a whole lot of nothing for a long stretch. From the very start on Thursday, 30 July, right through to the end of the run, we're looking at a solid blank period. The swell is tiny, the wind is all over the place, and the energy is just not there. There's a few days with a little bump, but it's all mixed up with dirty onshore wind or just plain weak.
The only glimmer of a chance, and I mean *a glimmer*, comes on the morning of Wednesday, 5 August. Portreath Beach is where the numbers are pointing. The water is a touch warmer than normal for this time of year at 65°F. The wind goes glassy, absolutely dead still, which is a huge positive. The swell is a tiny 3 ft out of the north, but the period is only 6 seconds, so it's pretty weak, short-period chop. The combined energy is a paltry 79 (weak), and the report says "surfable waves but very ordinary conditions". That's about as good as it gets. It's a fairly consistent spot, but even then, it's a real struggle. For a brief moment on Wednesday morning, there might be something knee-high to ride if you’re desperate, but it's not something to get excited about.
The rest of the time is just a write-off. For the next two weeks, everywhere else is a no-go. The wind is predominantly cross or onshore, the swell heights are under 2 ft, and the energy is mostly in the double digits. It's a long, flat spell.
If you’re a kite surfer, you might find some fun on the 7th and 8th of August when the wind is a fresh 19 to 22 mph, but for a paddle surfer, it's a hard pass. The forecast can change, but right now, it looks like a good time to get the gear out and do some repairs.
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.
