The Lowdown
Right then mate, Rusty here. Let’s have a look at what’s on the table for Crantock over the next couple of weeks.
Honestly, it’s a bit of a grim outlook for a while. The entire first week is a write-off. The swell is small, the period is short and weak, and the wind is mostly cross or onshore, chewing up what little bump there is. You’ve got moderate wave energy at best, with readings mostly below 100 (weak energy) and only a few days scraping past 100 (moderate energy). The water temp is sitting at 65°F with an anomaly of 3°F, so a touch warmer than normal for the time of year, but that won’t make up for the lack of waves. You’ll be staring at flat or messy, choppy conditions from the 4th right through to the 12th. There are about nine days of pretty much nothing to get excited about.
Now, there’s a tiny glimpse of hope. On Wednesday the 12th afternoon, we finally see a glimmer. The swell bumps up to 3ft from the west with a period of 10 seconds, and with a moderate offshore wind from the SE, it goes clean. Combined energy hits 116 (moderate). It’s not a standout and the score is only a 1, but it’s the first surfable moment. Not worth paddling out for unless you’re desperate.
The best of a quiet period comes Thursday the 13th through Saturday the 15th. The swell picks up to 4ft to 4ft from the west, with energy readings between 173 and 239 (moderate). But the wind is unfortunately onshore from the NW or cross-onshore from the N, which will make the surface lumpy and choppy. These are “poor surf conditions” across the board, so it’s more about the swell being there than it being any good. The period stays around 8 seconds – not great, not terrible. This spot is a river break, fairly consistent, and it likes a west swell, which matches. But the wind is the killer.
For a beginner, the 4ft to 4ft swell with onshore wind will be a handful and messy. For everyone else, it’s a frustrating wait. There’s nothing in this window that truly stands out. The wave energy never gets strong, the wind never truly cooperates, and the confidence drops further out. If you’re a kite surfer, some of those lumpy, cross-onshore afternoons on the 13th-15th might look more interesting than paddle surfing.
Stick to the long-range. Check back next week. Forecasts can change.

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.
