The Lowdown
Alright folks, Rusty here. Gonna be straight with you – the outlook for Gwithian over the next couple of weeks is a real tale of two halves. We’ve got a long, flat, and frustrating stretch ahead before things finally wake up. You’ll need some patience.
Right now, and for the next week and a half, it’s grim. From Thursday the 16th all the way through to Tuesday the 29th of July, we’re looking at a solid 13-day run of poor surf. The swell is tiny, mostly around 1ft to 4ft, and the period is short, so there’s just no power behind it. The winds are a mess too, mostly cross or cross-onshore, keeping the surface chopped up and messy. The combined swell energy is weak, struggling to get into triple digits, and the wave comment says it all: “poor surf conditions.” It’s a tough window for a paddle.
Finally, on Wednesday the 30th of July, we get a glimmer of hope. The morning shows a bit of life with a 3ft swell from the W, a 6-second period, and a clean offshore wind from the SE. The combined energy hits 100 – just barely into the moderate range. The afternoon is where it gets interesting. The swell picks up to 5ft, still from the W, and the wind goes glassy. That’s the standout moment. The water temp is about 63°F, which is just a touch above the norm for this time of year, so nothing wild.
Now, getting into the first week of August, the 31st of July brings a bigger, more powerful swell. The morning sees 6ft from the W with a 12-second period, which is a proper groundswell. The combined energy jumps to 800 – that’s strong. But, and it’s a big but, the wind is a fresh cross-onshore from the WSW, making it choppy and lumpy. The afternoon stays similar, with 5ft swell and the same messy wind. This is expert territory; the size and power are real, but the conditions are scruffy. It’s a setup that might actually be more interesting for kite surfing than a clean paddle session.
The 31st of July keeps the size up around 6ft, but the wind remains a problem, swinging cross and staying fresh. So, while the ocean has finally woken up, the quality is still poor. The best bet in this whole 16-day window is the glassy afternoon on the 30th of July. It’s the only time the stars align for a clean, surfable wave, even if it’s not massive.
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.
