The Lowdown
Alright folks, Rusty here. Let’s look at what’s on the table for the next couple of weeks.
Honestly, this is a pretty grim stretch to start. The swell window is open, but every time we get a pulse of size, the wind just wrecks it. We’re looking at a long, painful gap before anything even slightly worthwhile shows up.
From now until the end of August, forget it. On Tuesday the 25th and Wednesday the 26th we’ve got tiny 2ft to 2ft swell from the west, but the winds are all over the place and the water’s a touch warmer than normal at 65°, but nobody’s getting wet on that. Thursday the 27th through Sunday the 30th sees a bump in size – up to 7ft – but those fresh cross and cross-onshore winds turn the surface into a messy lump. The combined wave energy jumps to moderate levels on Saturday afternoon, but it’s junk. That 6ft on Sunday morning (August 30th) has clean conditions with a light cross-offshore wind, but the forecast calls it marginal at best.
The run of poor conditions continues right through to the 9th of September. There are a few moments that poke their head up. Tuesday morning, the 8th of September, offers the first real glimpse of hope. We get Crantock (a sheltered river mouth break) with a 5ft west swell. The wind is light and cross-offshore, making for clean conditions. The combined swell energy is modest, but that’s the cleanest wave in the whole window. Still, it’s only rated as surfable but very ordinary.
The following morning, Wednesday the 9th of September, we see a much bigger 8ft west swell with a longer 11-second period. The energy is strong, but the cross-onshore winds at 16 mph will make it choppy and messy. That’s expert-only territory in poor conditions.
The real standout, and I mean the *only* standout I’d bother pointing at, is that Tuesday the 8th of September morning. Clean, small, and calm. If you’re a beginner or just want a peaceful paddle, that’s your window. Everything else in this 16-day stretch is either blown out, too big and messy, or just plain flat. The gap from now until the 8th is nearly two weeks of dross. A blank run like this is pretty normal for this setup when the wind patterns lock in against the swell.
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.
