The Lowdown
Right then, let’s have a look at what’s on offer for the next couple of weeks at Crantock.
To be straight with you, it’s a rough start. The first ten days or so are a write-off. We’ve got a lot of wind and messy, lumpy conditions that just aren’t giving us anything rideable. The swell is there, don’t get me wrong – we see some solid 8ft waves on the 31st, but it’s blown out by a strong onshore wind. It’s one of those frustrating stretches where the ocean looks angry but not fun. The combined swell energy is moderate to strong at times, hitting 1263 on the 31st, but it’s all for nothing with that wind.
The first real glimmer of hope doesn’t come until Saturday, the 5th of September. And even then, it’s a slow burn. The morning is still a bit iffy with a light cross-onshore breeze and 6ft swell from the west, but the afternoon is where it’s at. We get a shift to a light offshore wind from the southeast, and the waves clean right up. The swell drops a touch to 6ft from the west, with a period of 10 seconds – that’s proper groundswell energy. The combined energy is a solid 540, and the conditions are described as clean. This is the standout session of the whole outlook. It’s not huge, but it’s rideable, and with that offshore wind, it’ll be glassy. For a river break like this, that’s as good as it gets.
The water temperature is about average for the time of year, nothing unusual there.
After that, the 6th of September brings a clean morning with 5ft waves and a cross-offshore breeze, but it’s a modest 380 energy. It’s a backup option, but it won’t beat the 5th. The rest of the week into the second week looks like more of the same messy story, with onshore winds and lumpy surf. The 13th of September has a tiny 2ft swell with a very long 15-second period, but the wind is cross-onshore, so it’s just not going to shape up.
So, in short: the first ten days are a bust. Your one real window is the afternoon of Saturday the 5th of September. That’s your best bet. It’s a clean, offshore session with decent energy from a solid groundswell. Get out there if you can.

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.
