The Lowdown
Alright, Rusty here. Let’s take a look at what’s on offer for Carbis Bay.
Honestly, the next couple of weeks are a real mixed bag, and a bit of a tough watch for the first week and a half. We’ve got a long stretch of poor conditions where the wind just won’t play ball. From the 10th right through to the morning of the 24th, it’s pretty much a write-off. The wind is mostly cross-on or cross, and the wave quality is just terrible. Even when there’s some swell, the chop and wind-ruffled surface make it hard work, and on the 14th, the water temperature is sitting at a touch warmer than normal for this time of year at 65°.
There’s a brief moment on the Thursday afternoon, 13th August, where the wind goes cross-off and it cleans up, with a 4ft swell from the west and a period of 10 seconds, but the combined energy is moderate at 284, and the call is only marginal. Not really something to get excited about, just a glimmer.
The real standout is much further out. Look at the morning of Monday, 24th August. That’s the one to circle on the calendar. The wind is glassy – dead offshore from the ESE at a paltry 3 mph – and the swell is a clean 3ft from the west, but with a very long period of 14 seconds. That’s groundswell energy, and the combined swell energy is a solid 492, which is strong. This isn’t a beach break that will close out; a 14-second period like that will wrap around the point and give you some proper lines. It’s a little more than a week away, so treat it as a promising call, but the signs are good.
Until then, you’re waiting for the wind to drop and the junk to clear out.
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.
Carbis Bay is 10 km (6 miles) from Camborne. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Camborne. Camborne has rooms for a wide range of budgets as well as car hire and transport links.
