The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming down the line for Portreath Beach. Straight up, I gotta be honest with ya – the next ten days or so are looking pretty grim. We’ve got a long, long stretch of days with nothing worth paddling out for. The surf just isn’t there, and when it does show a pulse, the wind’s gonna ruin it. After that, we might see a few windows open up, but we’re talking over a week away, so keep your expectations in check.
From Wednesday the 5th right through to Tuesday the 11th, it’s a total write-off. You’ll see a bit of swell around on the 5th, with waves hitting 6 ft from the west, but the wind is howling 16 mph from the WNW, smashing it onshore. It’s choppy, messy, and not worth your time. The combined energy is moderate at best (388), but with that wind, it’s just blown-out junk. The water’s sitting at 65°F, which is a touch warmer than usual for this time of year.
That poor run continues day after day. Thursday the 6th sees the swell drop and the wind stays on it. Friday the 7th turns glassy in the morning but the swell is a pathetic 1.0 ft – you’d need a lake for that. Saturday the 8th has a few moments with light offshore winds and clean conditions, but again, only 1.0 ft of west-southwest swell. There’s just no energy to work with. Sunday through Tuesday are much the same: small, weak, and crossed-up.
Now, we start to see a bit of life around Wednesday the 12th. The morning session actually looks rideable. The swell picks up to 3 ft from the west with a 9-second period, and the wind is a light 6 mph from the SSW, blowing cross-offshore. The combined energy climbs to 176, which is a modest step up. The conditions will be clean, but the waves are small and ordinary – nothing to get excited about, but at least you could get wet if you’re desperate. That afternoon the wind swings and chops it up again.
Thursday the 13th rolls in with a bigger pulse of swell – 6 ft from the west (energy at 422) – but it’s all onshore wind from the WSW at 12 mph, turning into a howling 16 mph onshore by afternoon. That’s a no-go. The swell builds even more on Friday the 14th, with 5 ft and energy of 493, but again, it’s onshore and messy. For an intermediate spot, this is just frustrating.
The best chance in the whole 16-day window looks to be Monday the 17th. We’ve got a solid 4 ft west swell (energy 257), but the real story is the wind – a fresh 19 mph from the SSE blowing straight offshore. That means clean, lined-up faces. The period is 9 seconds, which is decent. For Portreath, this is the standout. It’s not huge, but with offshore wind and clean conditions, it’ll be fun and rideable. The morning is your window. The afternoon holds similar conditions but with a bit of light rain. Just keep in mind, this is over a week out, so don’t book your flights yet – it’s promising but not certain.
After that, Tuesday the 18th drops off again, with the wind swinging onshore and the swell fading. Wednesday the 19th and Thursday the 20th are windy and small or onshore. The 20th sees a new pulse of 4 ft from the north, but it’s short-period slop at 5 seconds and the wind is cross-onshore and lumpy.
So, to sum it up: the next ten days are mostly a right-off. The only real glimmer is Monday the 17th with a clean, offshore morning on a decent west swell. If you’ve got a flexible schedule, that’s the one to aim for. Otherwise, you’re gonna be staring at flat, choppy water.
Stay patient, and keep an eye on the charts. Rusty out.

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.
