The Lowdown

G'day, I'm Rusty. Let's have a look at what's on the table for the next couple of weeks.

Right off the bat, I gotta be straight with you – the 16-day window is a tough one for Crantock. This sheltered river mouth setup is a bit of a tricky beast, and the charts are showing a pretty barren run. There's a big gap at the start with no real surf to speak of until Saturday morning the 22nd of August, and even then, it's a real struggle.

The first real chance to get wet comes Saturday morning the 22nd. We're looking at tiny 2-foot waves from the west with a 10-second period. The swell energy is a weak 114, so it's all very small. The wind is light from the east at 6 mph, which is cross-offshore and will keep the surface clean. It's ridable, but only just. You'll be scratching for scraps.

After that, it's a long, sad spell. The swell drops off to nothing, and while there's a few days of offshore winds, the waves are just too small to do anything with. The period from the 23rd right through to the end of the month is a write-off, with barely any energy in the water – those combined energy numbers are all in the double digits or low hundreds, which is just weak.

Now, there is a bit of a pulse of swell coming through around the 28th and 29th of August. We're talking 6 to 7-foot waves from the west. That's a big step up in size, and the combined energy jumps to 442 and then 638, which is moderate, pushing into strong. But here's the rub – the period is a short, weak 6 to 8 seconds, so it's all wind chop. The wind is onshore from the north-west and west, so it's going to be a messy, blown-out, choppy mess. For a river mouth, that's going to be a washing machine. Honestly, for a paddle surfer, it's a write-off. If you're into kite surfing, the big swell and strong wind might make it interesting, but for a surfboard, you can leave it.

The water temperature is ticking along about average for the time of year, so no need to worry about a wetsuit change just yet.

To sum it up: the first week is a total bust. The second week has size, but the conditions are terrible. The only tiny whisper of a chance is Saturday morning the 22nd for a micro-session on the clean, tiny waves. After that, keep an eye on the charts, but don't hold your breath.

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.
