The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer.
Honestly, it’s going to be a quiet month ahead. There’s nothing to get excited about in the entire 16-day window. The only break that’s really in the mix is Crantock, a river-mouth setup that’s sheltered and best for beginners when it’s clean. But the forecasts are a real struggle. The water is sitting at 65°F, which is a touch warmer than normal for this time of year, but that’s about the only thing that’s mildly pleasant.
From Friday 28 August right through to Saturday 12 September, every single session is rated as poor surf conditions. The swell energy is mostly weak, with values barely cracking three digits for most of the run. The only day with moderate energy is Monday 31 August, when the combined energy hits 1085 (moderate), and swell comes from the W at 8ft with a 9-second period, but the wind is onshore and strong – 30 km/h from the WNW – so it’s going to be messy and blown out. That’s too big for a learner anyway, and the conditions just aren’t there.
The best of a bad bunch might be Saturday 30 August morning, with a 5ft W swell at 9 seconds, cross-off breeze from the SSW at 25 km/h, and clean conditions. The combined energy is 348 (moderate). But it’s still a poor surf rating, so don’t expect much. There’s also Thursday 3 September morning with a 6ft W swell at 8 seconds, 358 (moderate) energy, and a cross-shore breeze at 25 km/h – that’s at least rideable, but again, poor quality.
After the first week, the swell drops right off. By 9 September, wave heights are under 3ft, and energy is below 100 (weak). The period gets short and the wind stays onshore or cross-onshore. It’s just not a good run.
Given the persistent poor conditions, strong onshore winds, and the beach-and-reef setup, this looks more interesting for kite surfing than paddle surfing over the next couple of weeks. For a surfer, it’s best to wait for a change.
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.
