The Lowdown
Alright, Rusty here. Let’s break down the next couple of weeks.
It’s a slow start. The first real surfable day isn’t until Tuesday, 25 August. Before that, the swell is small, the wind is off, and the conditions are just poor. You’re better off checking the surf report later.
The big standout is Tuesday morning, 25 August, at Carbis Bay. Swell hits 10ft out of the SW, with a 9-second period. That’s a lot of energy (1156) and the wind is cross-off, keeping it clean. Water temp is 64°, right around average for this time of year. This is the best swell of the whole run, but it’s big—only for the experienced crew.
After that, it’s a mixed bag. Wednesday the 26th has a morning with offshore wind and 3ft of swell, but it’s just ordinary. Thursday the 27th has 6ft but light cross-on wind, making it a bit lumpy. Not worth rushing out for.
The next real highlight is Tuesday, 1 September, afternoon session at Carbis Bay. Swell is 6ft from the WSW, 7-second period, with a moderate offshore wind. The guidance says “expect good surf conditions” and the energy is moderate (338). That’s a clean, fun wave.
After that, the 2nd of September has a weird long-period swell (19 seconds) but only 1ft. Total dud.
So, the two best calls are Tuesday morning, 25 August for the big SW groundswell, and Tuesday afternoon, 1 September for clean, offshore lines. Don’t expect much in between.
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.
Carbis Bay is 10 km (6 miles) from Camborne. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Camborne. Camborne has rooms for a wide range of budgets as well as car hire and transport links.
