The Lowdown

Alright folks, Rusty here. Let’s get into it for Portreath.

We’ve got a pretty grim stretch ahead, I’m not gonna lie. For the next week and a half, the wind is just relentless, coming from the wrong directions, and the swell is either non-existent or getting torn to pieces. It’s a real test of patience. The first real, half-decent window doesn’t show up until the morning of Tuesday the 4th of August, which is a long, dry spell of about a week with nothing worth paddling out for.

The water at Portreath Beach is sitting at 64°, which is a touch warmer than normal for this time of year, so at least you won’t be freezing while you’re sitting there waiting for something to happen.

Right, let’s run through the doldrums. Thursday the 23rd of July starts with a tiny 2ft northerly swell and glassy conditions in the morning, but the energy is weak (54), and the waves are just poor. It’s a tease. From there, it’s a parade of small, choppy, cross-onshore slop, with the wind howling from the N and NW, ruining anything that tries to form. Saturday the 26th sees a jump in size to 7ft from the WNW (417 energy), but it’s got 30 km/h winds on it, so it’s a messy, lumpy beast. Not for the faint-hearted. That pattern continues through to the end of the month.

The first bit of light comes on the morning of Thursday the 30th of July. We get a glassy, calm morning with a 3ft WNW swell (150 energy). It’s surfable, but the conditions are just “very ordinary,” so don’t expect much. Then it’s back to the wind and chop.

Now, the standout. The best on offer is the morning of Tuesday the 4th of August. The wind goes glassy, dead calm, with an easterly breeze – can’t get any cleaner than that. The swell is a solid 5ft from the west (293 energy), which is a decent size. It’s a 7-second period, so it’s a short-period windswell, but with that glassy surface, it’ll be the best shape we’ve seen in weeks. The direction is WNW, which is exactly what Portreath wants. It’s a bit of a wait, but that morning is your window.

Before that, on Monday the 3rd of August, we get a big pulse of 8ft west swell (925 energy), but it’s cross-shore wind and a short period, making it marginal. That’s more of a kite-surfing setup than a clean paddle session, to be honest.

To wrap it up, the first week and a half is a write-off. The real hope is that Tuesday morning, the 4th of August. Swell is a clean 5ft west, wind is glassy, get on it. After that, it fades back into small, choppy rubbish.

Stay patient, keep checking the forecasts, and I’ll see you in the water when it cleans up.

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.
