The Lowdown
Alright, Rusty here again. Let’s talk about Carbis Bay in feet and miles per hour. It’s a slow start, but there’s a big payoff if you can wait.
From Friday the 11th, it’s pretty flat and poor. You’ve got a 5ft west swell on Friday afternoon, but the wind is cross-shore and the energy is weak (292). Not worth wetting the suit. Saturday the 12th has offshore wind, but the swell is only 4ft to 5ft with a short period of 8 seconds. The energy is still low to moderate (263 to 371), and the surf is marginal at best.
Sunday the 13th is the first glimmer. Clean conditions with light cross-offshore breeze, a 6ft west swell, and a period of 10 seconds. The energy jumps to 585. It’s a good, fun day for a paddle, but nothing to write home about. Monday the 14th fizzles out with smaller, ordinary surf.
Then we hit a big dry spell from Tuesday the 15th all the way through Sunday the 20th. The wind howls from the NW and WNW at 19 to 25 mph, creating lumpy, cross-shore chop. The swell is there—sometimes up to 6ft—but the wind tears it apart. The energy peaks at 691 on Wednesday the 16th, but with that fresh breeze, it’s messy. This setup is better for kite surfers than for paddle surfing. There’s a brief clean moment on Wednesday afternoon the 16th, but it doesn’t last.
Monday the 21st brings back some hope. A 4ft WNW swell with an 11-second period and clean, light winds. The energy is a moderate 414. It’s a solid, clean session. The water is 63°F, which is a touch warmer than normal for the season.
Now, the big one. Thursday the 24th of September. The afternoon is the standout. A 8ft WNW swell with a very long period of 15 seconds, combined with a moderate offshore wind from the SW. The energy is massive at 2732. This is groundswell, powerful and lined up, but at that size it’s for experienced surfers only. It’s the best of the entire forecast. Friday the 25th is still good with a 6ft swell and clean morning conditions, but Thursday afternoon is the session to aim for.
After that, Saturday the 26th drops back to poor onshore conditions. So, hang in there. That Thursday the 24th is the real gem. The swell direction is right on the money for Carbis Bay, and the offshore wind will have it glassy.
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.
