The Lowdown

Alright crew, Rusty here. Let’s break down the next couple of weeks for Portreath Beach.

To be honest, we’re looking at a flat start. The first few days are a total bust. Monday the 10th and Tuesday the 11th are tiny and blown out. You’re wasting your time. The action doesn’t start until the 12th.

Wednesday the 12th is your first real window. The morning pushes a 3ft swell out of the west with a 10-second period, and the wind is a light, clean cross-off breeze. The energy is moderate at 126. The afternoon is similar, with a slightly smaller 3ft swell and still clean. It’s not a classic, but it’s the first proper surf and it’s rideable.

Thursday the 13th serves up a bigger 4ft groundswell from the west, with a solid 11-second period and a strong 317 energy reading. But the onshore wind is going to tear it to shreds. The same story plays out through the 15th, 16th, and 17th—decent swell energy, but the wind is just ruining it. It’s a real shame.

There’s a small reprieve on Thursday the 20th. The morning has a clean 2ft west swell with a 10-second period and a moderate offshore breeze from the ESE. The energy is a bit weak at 88, but the wind will be off, making it clean and lined up. The afternoon drops off, but the morning is your best bet for a tidy session.

Then we get to the big one. The 23rd of August is a monster. A 10ft swell from the WNW is forecast, with a massive energy reading of 1531. That’s a lot of power. But the wind is cross-onshore, making it a dangerous, messy beast. That’s strictly for experts, and even then it’s a dicey one. The 25th of August brings a very long-period 16-second groundswell from the west, with a strong energy of 420. The potential for a long, throaty wave is there, but the wind is onshore, so it’ll be a choppy mess.

The standout here is Wednesday the 12th. It’s the first clean surf of the run, with a 3ft to 3ft west swell and a light, clean breeze. It’s not huge, but it’s the only window where you’ll get clean, fun waves without a fight. The water is a touch warmer than normal at 65°, so you’ll be comfortable in a spring suit.

Overall, watch for Wednesday the 12th for a gentle paddle, and the morning of the 20th for a clean, small session. The rest is a write-off from the wind or just too big to handle. Portreath can get busy, but with this forecast, it might be quiet.

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.
