The Lowdown

Alright, let’s have a look at the guidance and finder info for this region. Right off the bat, I’ve got to be straight with you – this is a tough stretch for surf. The entire 16-day window is riddled with poor conditions, and the standout moments are few and far between. We’re talking about a long run of onshore winds, lumpy seas, and only fleeting glimpses of clean surf. The only break on the radar is Carbis Bay, but it’s a real tale of waiting and hoping.

The water at Carbis Bay is sitting at 65°F, which is a touch warmer than normal for this time of year – nothing radical, just a pleasant little anomaly.

The first real glimpse of anything decent doesn’t show up until Wednesday afternoon, August 12th. The wind swings cross-offshore from the SSE at 15 mph, and we get a clean 3 foot swell from the west at 9 seconds. The combined energy is weak (139), but it’s the only clean window in the first few days. Don’t get too excited – it’s surfable but very ordinary.

Then we hit a grim patch. From Thursday the 13th through to Monday the 19th, it’s a mess. Cross-on winds, choppy conditions, and a lot of nothing. The swell sticks around 2 feet to 4 feet, but the wind is mostly from the north or northwest, making a mess of things. The combined energy fluctuates between 57 and 319, but none of it is worth paddling out for.

Sunday the 18th and Monday the 19th see a brief shift with some offshore winds – Monday morning even has a 25 mph offshore from the WSW, but the swell is a pathetic 1 foot (13 energy). Tuesday morning the 19th shows a 5 foot WNW swell (217 energy) with a fresh offshore from the SW, but the period is only 6 seconds – short-period, windswell stuff. It’s clean, but weak and gutless.

Thursday the 20th brings a pulse of 7 foot WNW swell with a 9-second period and combined energy hitting 610 – that’s moderate energy. But the wind is howling from the NNW at 25 mph, cross-on, making it a total mess. If you’re a kite surfer, this might be your jam, but for a paddle surfer, it’s a no-go.

The final highlight comes on Thursday afternoon, August 27th. The wind is cross-offshore from the WNW at 9 mph, and we get a 4 foot west swell with a 10-second period and combined energy of 319. The setup is clean, with gentle breezes. This is the best of the lot – the only real standout in the whole outlook. It’s a long way off, so take it with a pinch of salt, but if you’ve got patience, that’s the one to pencil in.

Overall, this is a lean period. Carbis Bay is inconsistent, and the crowds are sometimes around. For the most part, you’re better off waiting for a change in the forecast. It’s a grim run, but it won’t stay this way forever.

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.
