The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s lined up for us over the next couple of weeks.
To be straight with you, the whole 16-day window is a bit of a struggle. There’s a long, quiet stretch at the start, and most of what’s on offer is small and messy. We’re looking at Portreath Beach as the only spot in the game, and honestly, it’s a tough watch.
The water at Portreath Beach is sitting at 63°, which is a touch warmer than normal for this time of year – a small mercy.
We kick off on Wednesday, July 15th, with tiny 1.0ft swell from the west, a period of 9 seconds, and a cross-offshore breeze. The combined energy is a weak 28, and the forecast calls it poor surf. That theme carries right through the first week. The mornings of Friday, July 17th, and Sunday, July 19th, offer a clean face with offshore and cross-off winds, but the swell is still tiny – 2ft and 4ft respectively – and the period is short at 5 to 6 seconds. It’s just not enough to get excited about.
The real kicker is that every single day from July 15th all the way through to July 29th is rated as "poor surf conditions" or "surfable waves but very ordinary conditions" at best. The wind is mostly cross-on or onshore, and the swell height rarely gets above 3ft. The energy values are all in the double digits, mostly under 100, which is weak.
Things try to change on Wednesday, July 30th. There’s a bump in swell to 5ft from the west, with a period of 6 seconds and a combined energy of 182 (moderate energy). But the wind is onshore and cross-onshore, making it choppy and messy. The forecast still says poor surf conditions. At 5ft, this is getting a bit too much for beginners, but with the onshore chop, it’s not a great look for anyone.
The standout on offer, if you can call it that, is the morning of Tuesday, July 21st. The swell is only 3ft from the north, period 6 seconds, but the wind is a light cross-offshore from the ENE, making it clean. The wave comment says "surfable waves but very ordinary conditions." It’s the only window in the whole 16 days where the wind is clean and light. Still, the combined energy is just 75, so it’s weak. Crowds are often here, so you might have company for those little dribblers.
Overall, there’s no big swell, no long-period groundswell, and the wind is rarely your friend. The setup at Portreath Beach is a beach, so with the onshore chop and small swell, it might actually be more interesting for kite surfing than paddle surfing. Don’t get your hopes up for this one.
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.
Portreath Beach is 5 km (3 miles) from Camborne. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Camborne. Camborne has rooms for a wide range of budgets as well as car hire and transport links.
