The Lowdown
Alright folks, Rusty here. Let's get stuck into this 16-day look at the Cornwall coast.
Alright, let's be honest from the get-go: we’re in for a bit of a rough patch. The first ten days or so are mostly a write-off thanks to onshore winds and messy conditions. The one real beacon of hope comes at the start of August. The water is currently around 65°F, which feels a touch warmer than normal for this time of year.
Portreath Beach is our only spot on the cards, and it’s a classic Cornish beach break exposed to the west-northwest.
For the rest of July, forget it. We’ve got a mix of strong onshore northwesterlies and choppy cross-shore winds messing up the lines. There’s a brief glimpse of something clean on the morning of Tuesday the 28th with a light cross-offshore breeze, but the swell is tiny at 3ft from the WNW and weak (110 combined energy). That afternoon turns glassy, but it’s basically flat at 2ft (84 combined energy). Not worth paddling out for.
The morning of Wednesday the 29th shows a glassy offshore wind from the SE, but again, the swell is barely a ripple at 2ft (55 combined energy). It’s a long stretch of poor surf conditions right through until the end of July.
Then, we get to the standout window. On Sunday the 2nd of August, things finally line up. The morning is looking magic. We’ve got 5ft of groundswell pushing in from the WSW with a period of 9 seconds, and the wind is totally glassy from the southwest. The combined energy hits a moderate 315, and the forecast is for good conditions. The afternoon gets blown out, but that window on Sunday morning is the one to circle on the calendar. It’s not huge, but it will be clean.
The following week is just more of the same wind and junk. We see a massive spike in swell on the 7th of August, with 12ft of WNW swell (combined energy over 2600!), but the onshore wind is howling. At a beach break with that much onshore power, it's going to be a washing machine – honestly, that set-up looks more interesting for the kite surfers than for paddle surfing. That’s strictly for experts only, and the wind makes it a mess.
So, to sum it up: it's a long, frustrating wait. The only true standout is the morning of Sunday, 2nd August at Portreath Beach, offering clean, glassy 1-2 foot waves.
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.
