The Lowdown
Alright, Rusty here. Let’s see what this stretch has in store.
To be straight with you, the start is flat and weak. We’re looking at a long gap of poor surf through the end of August and into the first week of September. The little bumps that show up are small and messy, with a cross-onshore breeze making a mess of them. A few cleaner windows pop up, but the swell is just too small to be worth the drive. A real dead spell.
Things start to crank up around Saturday, the 5th of September. That morning brings a big jump in energy (1877) with a 3.0m swell from the W, period around 10 seconds. It’s big, but the wind is cross-off, keeping it clean. However, 3.0m is serious size – expert-only stuff, and Carbis Bay can get crowded when it’s good.
The real standout is the morning of Sunday, the 6th of September. Carbis Bay is looking at a solid 3.0m of W swell with a 10-second period, and the wind is offshore from the SW. That’s a proper combo: clean, punchy waves with good energy (1669). Conditions are described as excellent for experienced surfers. This is the one to target. It’s a way off, so don’t lock it in yet, but it’s the best bet on the board.
Looking at the 8th and 9th of September, the swell stays big but the wind changes. The morning of the 8th has a fresh offshore from the SW, with 3.0m of W swell and a very long 12-second period. That long period gives the waves serious power, but at a beach break like Carbis Bay, it can make them a bit too straight. The energy is huge (3129), so it’s only for the brave and skilled. By the 9th, the swell drops and the wind goes cross-shore, so it’s less of a highlight.
Water temp is around 63°, which is about normal for this time of year, so your spring suit should be fine.
Bottom line: the first week is a bust. The big one to aim for is the morning of Sunday, the 6th of September – clean, offshore, and solid. The 8th morning is also a big-wave option for the experienced, but it’s not as clean. Keep an eye on the forecast.
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.
