The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ for the next couple of weeks.
First off, I gotta be straight with you – we’ve got a long, dry stretch ahead. The surf is gonna be a total no-show for the first week, from Thursday the 6th right through to Wednesday the 12th. That’s a solid seven days of pretty much nothing worth paddling out for. The swell is tiny, the wind is mostly on it or cross-onshore, and the energy is weak. You’ll see combined energy readings in the double digits, like 108 and 54, which is just sad. Don’t bother.
The first real glimmer of hope pops up on Thursday the 13th. Porth Beach is the only game in town, and it’s a beginner-friendly spot. The morning session is where it’s at. We’re looking at a 4ft swell from the west with a 10-second period, which is a bit of groundswell. The wind is dead calm, glassy conditions – that’s the major positive here. The water temp is about average for this time of year, so no weird surprises there. The combined energy hits 235, which is moderate, but the wave comment says it’s only “surfable but very ordinary.” Honestly, it’s not gonna be pumping, but if you’re desperate for a paddle, this is the only window worth a look. Expect crowds at Porth Beach, as it does get busy.
Things stay pretty ordinary right through to the end of the forecast. Friday the 14th and Saturday the 15th are a write-off with onshore winds and choppy conditions. Sunday the 16th morning has a little cleaner look with a cross-offshore breeze from the SSW, and a 4ft swell from the west-southwest, but the energy is moderate and the quality is still just “surfable.” The rest of the second week is a mix of stronger winds, shorter period swells, and lumpy seas. On Monday the 17th, a fresh breeze from the NNW hits 18 to 21 mph, with a 5ft northerly swell but only a 6-second period – that’s a choppy, blown-out mess and honestly, it’s more of a kite-surfing day than a paddle-surfing day.
So, the standout here is the Thursday 13th morning session at Porth Beach. It’s not a world-class wave, but with calm winds and a bit of west swell, it’s the best you’ll see. The rest of the 16 days is a near-total drought. Keep the board in the car, but don’t get your hopes up.

Information about the Porth Beach Surf forecast
The above surf forecast table for Porth Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Porth Beach can be found by selecting the local surf guide option on the grey menu. Our Porth 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 (Porth 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 Porth 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.
