The Lowdown
Alright, Rusty here, checking in with a look at our own little patch of coast. We've got a bit of a wait on our hands, so grab a coffee.
The next week and a half is flat and frustrating. Honestly, from now all the way through the 24th of July, it's a write-off. The swell is tiny and weak, with lousy wind for the most part. There's nothing worth paddling out for until we get to the very end of the period.
Right, so where's the hope? The first real glimmer shows up on the morning of Saturday, the 26th of July at Portreath Beach. Now, this is a big one. A chunky 5ft groundswell rolls in from the west, and get this – it's packing some serious grunt. The combined energy is a hefty 525. That’s a proper power surge. The period is a long 12 seconds, giving it some real shape and push. It's onshore wind though, so it won't be perfect, but the size and energy are undeniable. The day before, the 25th, is a 4ft swell but with a choppy cross-onshore wind, so the big Saturday swell is your target.
If you're an experienced surfer, the real standout is the Monday morning of the 27th of July. We're looking at a solid 6ft of west swell, with the combined energy all the way up at 610. That's some serious power. The period is a decent 10 seconds, so it's a full-bodied, west-facing groundswell. Wind is onshore from the WNW at 19 mph, so it’ll be lumpy and tough, but for the crew who can handle it, that's the only session in the whole two weeks that has any real weight to it. It's expert territory at that size.
The water temperature on the 14th is sitting at 64°F at Portreath, which is a touch warmer than normal for the time of year.
To be brutally honest, there's a massive, quiet gap for over a week before anything happens. When the swell does finally show up late on the 25th and into the 26th and 27th, it's big but windswept. The setup looks more interesting for the kite crew than for a clean paddle surf. For the most part, the conditions are poor. But that last weekend of July has some serious energy brewing. Keep an eye on it.
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.
