The Lowdown
Right, let’s switch over to feet and Fahrenheit for the landlubbers. Rusty here again, and the news ain’t any better for Carbis Bay.
The next sixteen days are a tough watch. For the first week, from Saturday the 15th all the way to Wednesday the 26th, it’s a whole lot of nothing good. The wind is either onshore or cross-shore, and it’s just tearing apart any tiny bit of sea that tries to show up. The wave energy is low, with combined swell readings mostly under 200 (117 on Saturday morning, 185 on Wednesday the 19th) and a lot of them are in the double digits – that’s just weak, no-power surf.
The one day that stands out is Thursday the 20th. It’s our best shot. You might see some chest-high waves pushing 5ft in the morning and 5ft in the afternoon, coming from the W and WNW with a period around 8-9 seconds. The wind goes cross-offshore from the WNW which will clean up the surface. The combined swell energy hits 352, which is decent, but it’s still a marginal call with a low score. It might be a bit lumpy, but if you need a paddle, it’s the only game in town.
After that, it’s back to the bin. Right through the 29th of August, it’s poor. There’s a tiny window on Thursday the 27th afternoon and Friday the 28th morning where the wind goes glassy, but with only 2ft of swell from the WSW, it’s basically a lake. The water temp is 65°, which is a touch warmer than average for this time of year, so at least the duck dives will feel okay.
Bottom line: Carbis Bay is a skip for the next two weeks. Don’t bother suiting 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.
