The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook for the next couple of weeks is a tough one. We’ve got a long stretch of nothing good to start, and then a bit of a pulse later on, but it comes with a lot of wind. Let’s walk through it.
We’re looking at Gwithian, and honestly, it’s a flat spell out of the gate. From Sunday the 19th right through the end of July, the swell is tiny, mostly under 3 ft, and the wind is cross or onshore for most of it. The wave energy is weak, with readings between 18 and 96 (weak energy), and the period is short, around 5 to 8 seconds. It’s just not doing anything. The water temperature feels about normal for this time of year.
The only flicker of a mention comes on the 31st of July, Friday morning. A strong offshore breeze from the ESE, 25 mph, will clean the surface up completely, but it’s a brutal paddle out. The swell is only 3 ft from the WNW with a short 6-second period, and the combined energy is just 110 (weak to moderate). It’s a beautiful-looking wave, but you’ll be fighting the wind to get into it. Not a beginner’s day.
Then, as we roll into August, the swell picks up. On Sunday the 2nd of August, we’re looking at 5 ft from the west, but it’s a short 7-second period, and the wind is howling from the WSW at 25 mph, making it a strong cross-onshore, lumpy mess. The combined energy hits 206 (moderate), but the quality is poor. This setup is more interesting for a kite surfer than a paddle surfer.
The standout, if you can call it that, is the morning of Monday the 27th of July. The swell is 5 ft from the west, with a 9-second period, giving us a combined energy of 332 (moderate). The wind is from the NW at 9 mph, so it’s onshore but light. It’s not perfect, but it’s the biggest, most energetic swell in the whole window. It’s still a poor surf condition though, so don’t expect magic.
Overall, it’s a long wait for not much. The best advice is to keep an eye on the forecasts for the first week of August, but don’t get your hopes up.
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.
