The Lowdown
Alright, Rusty here. Let’s break down the surf at Carbis Bay.
The 16-day outlook has a rough start. Wednesday morning brings a 3ft W swell, but cross-shore winds and poor conditions mean you’re better off on the beach with a coffee. The combined energy reads (545) – decent power, but the wind trashes it. Skip Wednesday.
Thursday afternoon gets interesting: a 7ft WSW swell, clean with fresh offshore wind, but it’s short-period at 7 seconds. The energy is (414), so it’s punchy, but it’ll feel fat and a bit crumbly. Marginal at best.
The standout is Sunday 13th. Sunday morning delivers a 5ft W swell with a solid 10-second period, light cross-off breeze, and clean conditions. Energy hits (521). Afternoon stays sweet: 5ft W, light offshore, glassy, with (386) energy. This is the day – smooth, lined-up waves for everyone from strong intermediates to experts. Water temp is about 64°, a touch warmer than average.
Friday 18th is another keeper. Morning: 4ft WNW, a long 12-second period, gentle cross-off wind, clean conditions and (345) energy. Afternoon keeps the quality: 4ft W, 11 seconds, light wind, (297) energy. That long period means groundswell – it will wrap in sweetly at this fairly exposed spot.
Monday 21st afternoon goes completely glassy – 4ft WNW, 10 seconds, no wind, good surf (325) energy. Glassy is gold. Tuesday 22nd morning is clean with 4ft W, 10 seconds, moderate offshore (268) energy.
Wednesday 23rd is a full-day winner: 4ft W, 11-second period, light offshore, clean both sessions – (396) energy each time. That’s a long-period groundswell that will attract the experienced crew.
Carbis Bay is inconsistent, so when it lines up like this, you gotta move. Crowds are possible on these days – bring patience.
The 16th throws a 10ft WNW swell with strong cross-onshore wind and messy conditions – big, ugly, and only for the skilled. Beginners, stay on the sand.
Your best bets: Sunday 13th and Friday 18th. Go get 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.
