The Lowdown
Alright, let’s see what we’ve got for Portreath Beach. I’ll level with you: it’s a grim outlook for the most part. The next week or so is made up of weak, small swell, with the wind almost always blowing onshore or cross-onshore, ruining any chance of clean waves.
It starts Tuesday afternoon with a 3 ft swell from the west and a 9-second period, with a cross-off wind from the south-southwest. The water temperature is about 65°, a touch warmer than average. Wave energy is modest (103). It’s surfable, but conditions are only ordinary, not something to chase.
Then we hit a real dead zone. From Wednesday the 29th through Monday the 3rd of August, it’s just poor. Swell stays under 3 ft, period is short – mostly 6 to 9 seconds – and the wind is constantly onshore or cross-onshore, making it choppy and messy. Energy drops as low as 25. It’s basically flat and blown out.
Tuesday the 4th of August shows a slight opening. A 4 ft swell from the southwest, 8-second period, and the wind goes glassy in the afternoon. Wave energy is moderate (145). Conditions clean up for a brief window, but the swell is small and the period is short. It’s a moment of peace, but not power.
From Wednesday the 5th right through to the 9th of August, we’re back to poor conditions. Onshore winds, small weak swell, energy mostly under 100. Nothing to get the heart rate up.
Now, looking out to Monday the 10th of August and beyond, we get a big jump in size. The swell hits 6 ft from the west on the 10th, with strong wave energy (512). But the wind is cross-on and onshore from the northwest, making it a rough, lumpy proposition for experts only. The period is just 8 seconds, so it’s not clean.
Tuesday the 11th of August brings 6 ft from the west-southwest, 8-second period, with onshore wind from the north-northwest. Energy is strong at 358, but you’re dealing with a messy, wind-blown wall of water. Wednesday the 12th pushes up to 7 ft and 8 ft from the west-southwest, still with that short 8-second period and onshore winds. Wave energy is very strong (634 to 800). That’s kite-surfing territory, not for a paddle surfer.
If I had to pick the *only* real standout – and it’s a weak one – it’s the Tuesday 4th of August afternoon with that glassy wind and a clean, surfable 3 ft. Otherwise, this is a month for patience.

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.
