The Lowdown
Alright folks, Rusty here. Let's have a proper look at what's on the cards for our local patch.
To be brutally honest, the outlook for the next couple of weeks is a bit of a struggle. We've got a real patchy run ahead. It kicks off on Tuesday the 11th with a tiny 0.7ft ripple from the west, but honestly, it's barely worth a mention. The real story is that we then have a long, frustrating gap. From that tiny Tuesday bump, it's a full week of nothing but poor surf conditions right through until the following Tuesday morning. That's a solid seven days of waiting it out.
The first real hope comes on Wednesday the 19th, but it's a bit of a tease. The swell is a weak 2ft from the west-northwest, but it's got a long period of 11 seconds, which means there's some energy in the water (174 combined energy). The problem is the wind is a cross-onshore, making it choppy and messy. It's not the one to get excited about.
The better, and really the only standout, option arrives on the afternoon of Monday the 24th. The swell jumps up to 7ft from the west, with a moderate 8-second period and a massive combined energy of 521. That's a big, powerful lump of water. Now, this is where I have to be straight with you: with that much power and a fresh cross-onshore wind, it's going to be a messy, heaving beast. At Crantock, a river break, that size is strictly for the experts only. Beginners need to stay well clear. The water temperature is a touch warmer than normal for this time of year, coming in at around 66°.
For the rest of the run, it's a whole lot of cross-onshore wind and small, weak swell. There's another pulse on the morning of Wednesday the 26th with a 5ft westerly swell, but it's a short-period wind swell and cross-onshore again. The wind is light, though, so it won't be as blown out, but it's still not going to be a classic.
So, to sum it up: if you're a seasoned charger looking for some power, the afternoon of the 24th is your window, but expect a battle. For everyone else, it's a waiting game. The consistency isn't there, so keep an eye on the charts, but this is a pretty normal blank run for this area.
Stay safe, and I'll see you in the water when it cleans up.
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.
