The Lowdown
Alright mates, Rusty here. Let’s call it what it is – this 16-day stretch for Gwithian is a tough one. The first few days are a total write-off. From Friday the 31st of July through Sunday the 2nd of August, we’ve got nothing but poor surf. The swell is tiny, the wind is all over the place, and it’s not worth getting wet. There’s a big gap at the start with no real surf.
The first little chance appears on Monday morning, the 3rd of August. The water is 65°, which is a touch warmer than normal for this time of year. The swell is a small 3ft from the WSW with a 9-second period, and the wind is glassy – dead flat, no ripples. The combined energy is still weak (113), but for a couple of hours in the morning, if you’re really keen, you might find a little ankle-biter. It’s surfable, but it’s nothing special.
The pattern doesn’t improve. Tuesday the 4th has a bit more push at 4ft from the WSW, but the period drops to a short 7 seconds and the wind is a moderate cross-onshore, chopping the surface up. The energy is moderate (161), but the quality is poor. This same story repeats for the next week – small, wind-affected waves. The best of a bad lot comes on Sunday the 9th of August. The morning has a clean 3ft from the WSW with a 9-second period and a light cross-offshore breeze from the SSE. The energy is a moderate 101. It’s a clean, small wave, but it’s not a standout. The crowds at Gwithian can be often, so even on a small day, you might have some company.
The second week is more of the same with no real highlights. The swell stays small, under 3ft, and the wind is consistently onshore or cross-onshore. There’s a moment on Tuesday the 11th of August with 2ft from the W, a 9-second period, and glassy conditions, but the energy is weak (72) and it’s just too small to get excited about. Honestly, for the whole 16 days, there isn’t a single day that truly stands out. The only half-decent shots are the morning of the 3rd of August or the morning of the 9th of August. The rest of the time, it’s a flat spell with a lot of wind. If you’re a kite surfer, the strong onshore winds on the 15th of August might look more interesting than a paddle.
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.
