The Lowdown
Alright folks, Rusty here. Let’s be straight with you—this stretch is gonna test your patience. The next week-plus is looking pretty grim for any real waves. We’ve got a long gap of small, weak, and messy surf ahead. There’s really only one short window that’s worth getting excited about, and it’s a ways out.
We're starting off with a real dud. Through the weekend and into the early part of next week, we’re looking at tiny, weak surf. The energy is just pathetic, with readings mostly in the 40s and 50s (weak energy). Winds are mostly onshore or cross-onshore, chopping up what little is there. It’s not worth the paddle.
There’s a brief moment on Monday, August 3rd, where the morning goes glassy. That’s a real positive, but the swell is still tiny at 3ft from the WSW with a period of 9 seconds. You might get a few grovelly ones at Gwithian, but overall it’s just ‘surfable’ at best. Nothing to write home about.
The mid-week is more of the same. Weak and messy. By Friday, August 7th, it’s almost flat. That’s a long, frustrating run.
Finally, we start to see a pulse coming in around Saturday, August 8th. The swell builds to 4ft out of the southwest, and the energy starts to pick up, hitting 132 and 164 (moderate wave energy). The winds are offshore and light, so the conditions are clean. This is where it starts to get interesting. It’s still a beach break, and with that period only around 6 seconds, it’s not going to be a world-beater, but it’s the best we’ve seen in a while.
The standout is the morning of Sunday, August 9th. That’s the one to circle on the calendar. We’ve got 4ft of SSW swell, a period of 8 seconds. But the key here is the wind: a proper offshore ESE breeze, blowing at 12 mph. That’s going to make Gwithian (Cornwall) clean and lined up. The energy is up at 196 (moderate wave energy). For a beach break, it should actually be pretty fun. This is your window.
After that, the forecast gets a bit more uncertain as we get into the second week. Monday, August 10th looks clean with a cross-offshore wind, but the swell is a bit jumbled from the north. It's not as good as Sunday. From there, it looks like it fades out again, with winds turning onshore and the swell dropping right back off. There’s a mention of a bigger northwest groundswell on Wednesday, August 12th, but with a fresh onshore breeze, it’s going to be a messy, blown-out mess, not worth your time. The long-range stuff for August 15th is just a tease, a tiny 0.3ft blip with a 13-second period that won’t do anything.
So, mark your calendar for the morning of August 9th. Get up early, get the offshore wind, and make the most of it. It’s the single best chance we’ve got in this whole sorry stretch. Everything else is a pass.
Stay salty.
Rusty.

Information about the Gwithian Surf forecast
The above surf forecast table for Gwithian provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Gwithian can be found by selecting the local surf guide option on the grey menu. Our Gwithian 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 (Gwithian) 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 Gwithian 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.
Gwithian is 6 km (4 miles) from Camborne. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Camborne. Camborne has rooms for a wide range of budgets as well as car hire and transport links.
