The Lowdown
Alright folks, Rusty here. Let’s have a look at what Portreath Beach has got cooking for us over the next couple of weeks. Gotta be straight with you – it’s a tough stretch. The swell is small and the wind is mostly a pain, so we’re looking at a long, quiet run before we even get a sniff of anything rideable.
The first few days are basically a write-off. From Saturday the 8th right through until Monday the 10th, we’ve got tiny 1ft to 3ft swell with short periods and poor conditions. Sunday the 9th has a clean northwesterly breeze, but the swell is so weak it’s barely a ripple. Don’t bother.
Things don’t improve much through the middle of the week. Monday the 10th is cross-onshore and choppy, and even though Tuesday the 11th has clean offshore winds from the ESE, the swell drops right down to 1ft and then 0.7ft with a very long 13-second period on the afternoon – but there’s no energy to back it up (combined energy of all swells directed here is a measly 31). You’d be scratching for anything.
Wednesday the 12th is where we finally see a tiny glimmer. We’ve got a clean morning with a light cross-offshore breeze and the swell bumps up to 3ft from the west, with a 10-second period. The combined energy is still moderate at 159, and the conditions are clean. It’s surfable but very ordinary. This is your only real option for the first week. The water temperature is sitting at 65°, which is a touch warmer than normal for this time of year, so you won’t need a thick suit. Keep your expectations low.
Then we hit another wall. From Thursday the 13th through to Sunday the 23rd, it’s a long, grim stretch. The swell tries to build a few times – like on Wednesday the 19th when it hits 6ft from the west – but every single session is ruined by onshore or cross-onshore winds. Thursday the 20th afternoon sees the biggest energy spike of the whole forecast with a combined energy of 520, and a 5ft swell from the west-northwest with a 10-second period, but it’s cross-onshore and choppy. Too messy for a good paddle. If you’re into kites, that afternoon might look more interesting than surf.
The only other barely surfable moment comes on Sunday the 23rd morning, with a gentle offshore from the southeast and a clean 2ft west swell (combined energy 83). It’s small and weak, but at least it’s clean.
Honestly, the standout here is Wednesday the 12th. It’s not a classic, but it’s the cleanest and most consistent option we get. If you’re desperate, that’s your window. Everything else is either too small, too windy, or both.
Stay patient, lads. It’s a flat spell, but it won’t last forever.
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.
