The Lowdown
Alright, folks, Rusty here. Let’s take a look at what’s cookin’ for Gwithian over the next couple of weeks.
Straight up, it’s a painful start. The first real surf recommendation doesn’t show up until Saturday, the 15th of August. That’s a solid week and a half of nothing but poor surf conditions and onshore junk. We’ve got a few pulses of swell, but the wind is just wrecking everything – strong cross and onshore winds from the south-west and west. The water’s a touch warmer than normal for this time of year at 65°, but that’s small comfort when you’re staring at a lumpy mess.
The standout window is Sunday, the 16th of August. That’s the day to keep your eyes on. We’ve got a solid 5ft swell rolling in from the west, with a period of 8 seconds. The combined energy is strong (343-349), but the real magic is the wind. It’s glassy – glassy! – with light easterly and westerly breezes. That means clean, smooth conditions. The crowd profile at Gwithian is "often" busy, so on a Sunday with clean surf, expect company. It’s a beginner-friendly spot, so that 5ft swell is a good size for a fun session, not too daunting.
The 15th of August is a runner-up. Saturday morning shows 5ft from the west, 8 seconds, with a light cross-shore breeze. The energy is strong (339), but the wind is a little more on the nose, so it won’t be as perfect as Sunday. Still, it’s the first decent option in a long, dry spell.
The rest of the second week? Honestly, it’s a bit of a letdown. The 17th of August has a touch more size at 6ft, but the wind swings cross-on from the north-west, putting a chop on it. You’ll get waves, but it’ll be a battle.
Overall, this is a tough forecast. The first week is a write-off. The 16th is your golden ticket. Mark it.
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.
