The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

To be straight with you, the forecast is a tough one for the whole 16-day window. The first real chance of even a splash happens on Monday morning, 3rd of August. Up until then, we’ve got nothing but a flat spell with poor, weak windswell and cross-onshore junk. There’s a solid gap of nothing from now all the way through to Sunday, 2nd August, so don’t bother waxing up before then.

The only spot in the game is Portreath Beach. Water’s sitting at 65°F which is a touch warmer than normal for this time of year, so that’s a small win.

Let’s talk about the standout. Honestly, there’s only one session that looks even half decent in the whole 16 days, and that’s the early morning of Monday, 3rd August. We’ve got a 3 ft swell rolling in from the WSW with a period of 9 seconds, and the combined energy is moderate (113). The wind is glassy, dead calm, so the surface will be clean as a whistle. It’s surfable, but the waves are very ordinary – small, weak, and nothing to write home about. For a local surfer it’s worth a paddle if you’re desperate, but it’s not going to be memorable.

The other highlight is a bit further out. Sunday morning, 9th August, we get a clean window with offshore winds from the SSE at 6 mph, and a 3 ft WSW swell at 9 seconds. Combined energy is moderate again (101). It’s clean, but the size is tiny. It’s surfable, but only just.

The rest of the weeks are a write-off: cross-onshore winds, choppy conditions, and tiny swell. Anything over 3 ft gets blown out by the wind. The Tuesday (4th August) sees a bit more size at 4 ft, but the period is short (7 seconds) and the wind is cross-shore, making it a messy, lumpy affair. Not worth your time.

A couple of mornings on the 2nd of August and the 10th of August have offshore winds, but the swell is tiny – 2 ft or less. You might get a knee-high ripple, but it’s a long paddle for nothing.

The 11th of August starts glassy calm with a 2 ft swell from the west, but again, it’s ordinary. The 13th of August has a clean cross-off window in the morning, but the swell is only 2 ft.

Bottom line: if you’re a beginner, there’s nothing over 5 ft here, so you’re safe from getting smashed, but there’s barely anything to ride. For experts, there’s no power to work with. The energy is weak across the board. The setup here is more interesting for a kite surfer than a paddle surfer for most of it.

Keep your hopes low, but check back in a few days – forecasts can change.

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.
