The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Carbis Bay over the next couple of weeks.
First thing’s first – it’s a rough start. We’re looking at a long spell of flat, messy conditions. For the first week and a half, there’s practically nothing worth paddling out for. The energy is weak, the winds are all over the place, and the swell is tiny. We’re talking a solid eight or nine days of just poor surf. You’d be better off cleaning the wax off your board than trying to get wet.
Then, things start to stir. The first real glimmer of hope shows up on the 17th of August – Monday morning. We’ve got a 5ft swell from the west at 9 seconds, and the wind is a clean cross-offshore from the WNW. That’s a proper improvement. The energy is moderate (304), and the water is clean. It’s a solid, if not spectacular, option for a session. The afternoon on the 17th jumps up to 5ft from the west, but the wind swings to a fresh cross-shore from the NW, making it lumpy. Still, it’s the best we’ve seen.
Now, the standout window is the 18th of August – Tuesday. The morning sees an 8ft swell from the WNW (8 seconds), and the afternoon is the same size with a slightly longer 9-second period. The combined energy jumps from a strong 798 in the morning to a very strong 1035 by the afternoon. This is a powerful, solid swell. Problem is, at 8ft, this is expert territory only. The wind stays moderate cross-shore, so it’ll be a bit of a battle with a cross-chop. This is a big, powerful, and thumping day. If you’re not experienced, stay on the sand.
After that, the swell drops back down. The 22nd of August (Saturday) offers a 6ft swell from the WNW with light winds in the morning, but the period is a short 8 seconds, so it’ll be a bit weak and messy. Still, it’s a goer.
The standout is undeniably the 18th of August. That’s the biggest and most powerful swell of the whole period. If you’re an expert, that’s your day. For the everyday surfer, the 17th of August is the most balanced day with clean conditions and a manageable size.
Water temp is about average for the time of year, nothing wild to report.
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.
