The Lowdown
Alright folks, it’s Rusty here. Let's have a look at what's on the menu for Carbis Bay over the next couple of weeks.
To be straight with you, it’s a bit of a lean stretch. We’ve got over a week of pretty ordinary conditions before anything really worth paddling out for shows up. The first real chance of a surf comes in on Thursday, August 20th, but even then it’s only just creeping into the "maybe" zone.
The early part of the window, from the 15th through to the 19th, is basically a write-off. The wind is mostly cross or cross-onshore, making for lumpy, choppy, and generally poor surf. The swell is small and weak, and the wave energy is low, barely breaking 100 (36 to 132 mark). The water temp is sitting at 65°F, which is a touch warmer than normal for this time of year, so that’s one small comfort if you’re a hardy soul.
Now, Thursday, August 20th, things start to look a little more interesting. The morning sees a WNW swell at 5ft, with a period of 8 seconds, and the wind is a clean cross-offshore breeze from the WNW at 9 mph. The combined wave energy climbs to a moderate 406. It’s still not a standout, but it’s the best we’ve seen by a long shot. The afternoon holds similar energy at 349, with a slightly smaller 4ft swell. It’s a marginal call, but it’s the pick of the fortnight.
After that, it drops right back off. Friday the 21st is a write-off again with cross-onshore winds and messy surf, and the rest of the month looks small, weak, and mostly blown out. The one exception is a glimmer on Thursday, August 27th, when the wind goes glassy in the afternoon. The swell is only 2ft from the west at 9 seconds, with energy at 99, so it’s tiny, but it’ll be clean. Definitely a longboard or funboard only kind of day.
The standout: If you’ve got to pick a window, Thursday, August 20th is your best bet. Head to Carbis Bay in the morning. You’ll have a WNW swell around 5ft and a clean cross-offshore wind. It’s about as good as it’s going to get in this stretch. The afternoon is still surfable but a touch smaller. Don’t expect perfection, but it’s the only real chance at a decent wave.
Crowds are possible here, so expect some company if the swell shows up.
Rusty.

Information about the Carbis Bay Surf forecast
The above surf forecast table for Carbis Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Carbis Bay can be found by selecting the local surf guide option on the grey menu. Our Carbis Bay 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 (Carbis Bay) 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 Carbis Bay 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.
