The Lowdown
Alright folks, Rusty here, taking a look at what's cookin' at Portreath Beach over the next couple of weeks.
The vibe for the next week and a half is honestly pretty grim. We're looking at a long dry spell of small, messy, and mostly onshore junk. After that, there's a brief flash of something worth paddling out for on the 21st, but it's a short window before the wind turns against us again.
The water temp's sitting pretty average for this time of year, nothing weird going on there. Not that it'll matter much, because for the next ten days, it's a long wait.
Let's be real, from now right through until the 20th, it's a write-off. We've got tiny waves – most days are well under 3 feet – with wind that's almost constantly cross-onshore, onshore, or just lumpy. The swell energy is weak, mostly sitting under 100, sometimes nudging a bit higher but still rubbish quality. You'll see some longer period swell on the 13th (11 seconds) but it's pinned under a strong onshore breeze, so it's just a messy, blown-out 4 foot. Not worth your time.
Now, there's a glimmer on Friday the 21st. The morning kicks off with a clean 6 foot swell from the WNW, energy pumping at 415 – that's a proper step up. The wind is a gentle offshore from the ESE, so it should be clean. Then the afternoon gets even better: a 8 foot swell from the west, energy hitting 650, with a light offshore from the SE. This is the standout period. For a surf break that's fairly exposed to the north-west, this is as good as it's gonna get. Be warned, though – at 8 feet, that's expert territory, especially for an intermediate spot. Morning might be the call for the more able intermediates, but the afternoon is for the experienced crew.
The buzzkill? That window slams shut fast. Saturday the 22nd the wind swings onshore from the west again, and we're back to choppy, cross-onshore 7 foot leftovers. The week after that just fades back into small, weak, and blown-out conditions with rain showers.
So here's the deal: sit tight. Do not waste a session until Friday the 21st. If the forecast holds, that day will be the one. It's a long-range call, so keep an eye on it, but that's your best – and only – shot.
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.
