The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for our little patch of coast.
Right off the bat, I gotta be straight with you: the next ten days or so are gonna be a real struggle. We’re looking at a long, dry spell with nothing worth paddling out for. From Tuesday the 28th of July right through to Monday the 10th of August, it’s mostly small, weak, and messy. You’ll see a few mornings with a bit of waist-high swell, but the wind is just never on our side – mostly onshore or cross-onshore, and that’s gonna chop it up good. The 30th of July morning has the biggest lump of the early period at 4 ft, but it’s a short-period 6-second windswell with a 12 mph onshore breeze, so it’s just a washing machine. No go.
We do have a glimmer, though. Tuesday morning the 4th of August sees a little pulse of 3 ft swell from the north with a clean offshore wind from the southeast at 16 mph. That’s the best looking window in the first two weeks, but even then, the swell period is a weak 6 seconds, so it’s not gonna have much push. The combined energy is only 96, so it’s weak. It’s surfable, but barely.
Now, the real story is the last couple of days of the forecast. Monday the 11th of August looks promising. The morning has a 4 ft swell from the southwest with a moderate cross-offshore breeze – that’s clean. The combined energy jumps to 214, so we’re talking moderate wave energy. Then Tuesday the 12th of August morning is a standout for the big dogs only: a solid 8 ft from the west-southwest, but it’s a dumpy 8-second period and the wind is onshore. That’s a lot of water moving around, and only for the experienced crew. The energy is strong at 636.
So, the best real chance to get a proper session is likely Tuesday the 11th of August. The swell direction (SW) lines up nicely with the optimum for Portreath Beach, and that clean cross-off wind will make for some tidy lines. If you’re feeling brave, the 12th might have size, but it’ll be a battle.
Hang in there, the wait might be worth it.
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.
