The Lowdown
Alright everyone, Rusty checking in. Let's cut through the chatter and look at what's actually rideable in this next 16-day stretch.
Truth is, it's a tough start. The first week is mostly a write-off with a lot of onshore junk and chop. We're staring at a long gap before anything decent shows up.
The only real standout lands on Sunday, August 2nd. That morning at Porthtowan, we get a sweet 7 ft swell from the WSW, tracking with the optimum. The wind is a gentle offshore from the SSE, cleaning it right up. The energy’s solid (521), and it’ll be clean. The afternoon stays good with a 6 ft swell and the same offshore flow. That Sunday is the day.
Before that, Thursday morning, July 23rd is the only other nod. It’s tiny—just 3 ft from the NNW—but it goes glassy. Worth a look for a longboard or a beginner session.
After that Sunday, the wind swings bad again, ruining the Monday and Tuesday. There’s a brief moment of glass again on Wednesday morning, August 5th with a 3 ft west swell, but that afternoon wind cranks back up and wrecks it.
It’s a long haul for one good day. The water is sitting about 64°, which is slightly warmer than usual for this time of year.
Get your gear ready for that Sunday.

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