The Lowdown

Alright, Rusty here. Let’s cut through the noise on this forecast. It’s a grim outlook for Crantock, with a lot of flat and messy days. The water is sitting a touch warmer than usual at 19°, but that’s the only nice thing I can say.

Your first real shot at getting wet is Saturday the 22nd of August in the morning. There’s a tiny 2ft swell from the W with a 10-second period, giving a weak combined energy (118). The wind is a light easterly cross-offshore, so it’s clean, but the waves are barely there. It’s a long-period groundswell with no punch.

Sunday the 23rd is even smaller – 0.7ft of swell from the WSW with a very long 14-second period. The combined energy is a pathetic 38. It’s clean with a light cross-offshore, but you’ll be sitting on a flat board.

From Monday the 24th through the 25th, the energy is in the teens and twenties. The winds are offshore, keeping it clean, but the swell is essentially non-existent. You’re looking at a few days of nothing.

The next flicker comes on Wednesday the 26th of August afternoon. A 3ft W swell with an 8-second period pushes the combined energy to 203. The wind is a light cross-offshore, so it’s clean. It’s a very ordinary, choppy wave, but it’s the most energy you’ll see in a while.

Thursday the 27th of August morning is the pick of the litter. The wind goes glassy, and there’s a 3ft W swell with a 10-second period, giving a combined energy of 177. It’s clean and glassy, but still small. For a beginner or a longboarder, this is the window.

The end of the first week of September brings some size, but it’s a total loss. Thursday the 3rd of September afternoon has a 7ft W swell with an 8-second period, pushing combined energy to 501, but a 31 mph near-gale cross-shore wind is tearing it apart. That’s a complete mess.

There’s nothing to get excited about here. The best window is that Thursday morning (27th) with the glassy conditions, but it’s not a standout. The rest is a long, flat slog.

Rusty.

Information about the Crantock Surf forecast

The above surf forecast table for Crantock provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Crantock can be found by selecting the local surf guide option on the grey menu. Our Crantock 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 (Crantock) 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 Crantock 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.

Crantock is 2 km (1 miles) from Newquay. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Newquay. Newquay has rooms for a wide range of budgets as well as car hire and transport links.
