The Lowdown

Alright, folks, Rusty here. Let's be straight with you about the surf ahead. It’s a bit of a waiting game for the next week and a half, but there are a couple of windows that could get the heart rate up, especially if you’re an experienced surfer. We’re looking at a pretty flat start, so don’t get too keen on the short term.

The first week is a real struggle. From Saturday the 8th through to the 17th, the swell is tiny, mostly around 1 to 3 feet, and the winds are mostly cross-shore or cross-onshore, chopping up what little is there. You could paddle out at Carbis Bay and catch a few foam balls, but it’s honestly not worth the effort. The water’s sitting at 65°, which is a touch warmer than usual for this time of year, but that’s about all the good news there. The energy in the water is weak, with combined energy values in the double digits, like 21 on Saturday morning. It’s just not doing anything.

We do see a slight improvement on Wednesday the 12th, with a bit more push from the west-southwest at 3 feet, but the wind is light and it cleans up for the afternoon. It's surfable, but very ordinary. Same with the 16th and 17th – surfable but still just background-level stuff. The energy starts to climb into the low hundreds, but it’s still far from exciting. This is a period for tinkering with your gear, not for getting wet.

Now, here’s where it gets interesting. Keep your eyes on the 19th and 20th of August. We’ve got a proper pulse of west-northwest swell that swings through. On Wednesday the 19th, expect the swell to build to 7 feet by the morning and 8 feet in the afternoon. The wind is offshore and clean, which is a big plus. The energy combines to a solid 480 on Wednesday morning, jumping to 597 in the afternoon. This is real surf, but at that height, it’s going to be too much for the beginners. You need to know what you’re doing. The period is around 7-8 seconds, so it's a bit short period, and it might be a little walled up at a beach break. This is where Carbis Bay’s setup might get a bit tricky, as the short-period swell could be a bit sectiony, but it’s the best we’ve seen.

Thursday the 20th is the standout. Morning brings 8 feet of west-northwest swell with a clean offshore wind. The energy is cranking at 940, which is strong and powerful. That’s a big day, well into expert territory. Don't even think about it if you're not comfortable in serious, powerful surf. The afternoon drops a touch to 6 feet but the wind swings to a cross-on, which will chop it up a bit, so the morning session is the one to be there for.

After that, it backs right down again. From the 21st onward, we're back to small, weak leftovers with onshore winds. The 22nd and 23rd are small, wind-affected, and just not worth the paddle.

So, to sum it up: don't bother this weekend or the early part of next week. Mark the 19th and the morning of the 20th on your calendar. The 20th looks like the biggest and most powerful, but the 19th has that clean offshore wind. For the more experienced crew, that’s your window. Be patient, it’ll be worth it.

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.
