The Lowdown
Alright folks, Rusty here. Let’s break down what Gwithian’s got coming up for the next couple of weeks.
I’ll be honest – this forecast is a long, slow grind. From the 26th of July right up until the morning of Sunday, the 9th of August, it’s a total write-off. We’re talking a solid two-week gap with no real surf to speak of. The wind is mostly onshore or cross-onshore, the swell is tiny or weak, and the wave quality is just poor. The water’s a touch warmer than usual at 65°F, but that’s small comfort when you’re looking at a flat ocean. The combined energy is weak for most of that stretch, sitting in the double digits or low hundreds – nothing to get your heart rate up.
The only bright spot in the entire 16-day window hits us on Sunday the 9th of August. That morning, Gwithian is going to see a solid 8ft swell from the WNW. The wind turns glassy with a light offshore from the ENE. The wave report says "expect very good surf conditions." By the afternoon, it bumps up to 8ft from the WNW, with a combined energy reading of 806 (strong wave energy) and the wind goes flat calm – glassy as can be. At that size, this is strictly for experts – it’s over 8ft, powerful, and not a beginner’s wave. The swell direction is dead on for Gwithian’s best exposure. It’s a consistent spot, so expect crowds to be likely. The period is around 7-8 seconds, nothing crazy, but with that size and glass, it’s going to be a proper session for the right crew.
After that one amazing day, the 10th of August brings fresh southerly winds and the quality drops straight back into the gutter.
So, here’s the takeaway: mark your calendar for Sunday the 9th of August if you’ve got the skills. The rest of the time, you’re better off staying home and watching old clips.
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.
