The Lowdown
Alright, this is Rusty, and I gotta be straight with you. Looking at the forecast for Crantock over the next couple of weeks, and it’s a bit of a mixed bag. The surf check for September 11th through the middle of the month honestly looks pretty rough – a lot of onshore and cross-shore wind messing up what could be decent swell. We're looking at a stretch of poor conditions for the first week or so.
The water temperature is about what you’d expect for this time of year, nothing wild.
So, for the early part, for example on Friday the 11th, we’ve got a 5-foot swell from the west, but that NW wind is just going to trash it. The wave energy is moderate (373) but with those conditions, it’s not one for the water. This pattern keeps up through the weekend and into next week. Monday the 14th morning offers a brief window of cleaner conditions with a lighter SSW wind, but the swell is only 3 feet with moderate energy (163), so it’s small and average.
The real standout… and you’re going to want to circle this date… is way out there on September 25th. Friday morning looks phenomenal. We’ve got a solid 10-foot swell rolling in from the west. The wind is glassy – a light easterly at 3 mph. That’s a major positive. The wave energy is strong (1285), and with that size, this is one for experienced surfers only. For a river break like this, a long period west swell with clean conditions could set up some proper waves. This is the one to wait for.
Before that, September 23rd morning also shows some promise. The 23rd has a 7-foot west swell and, get this, glassy conditions with zero wind. Score. Energy is moderate (518), but that clean face will make it surfable.
The 22nd of September Tuesday morning is a smaller option – 3-foot west swell with a light offshore SE wind at 9 mph, keeping things clean. Low energy though (131).
You’ve got a big gap of uninspiring surf before that 25th. It's a long-range call, so a little less certain, but if it holds, it’s the best on offer. Keep an eye on the forecast.
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.
