The Lowdown
Alright folks, Rusty here. Let’s break down what’s happening at our local spot.
Right off the bat, the water temperature is sitting at 65°, which is a touch warmer than normal for this time of year—nothing wild, but you’ll notice it’s a bit more comfortable than usual.
The next 16 days are a real mixed bag for Crantock. The first week is pretty much a write-off with poor surf conditions dominating. A big pulse of swell hits on Monday 31st August with 8ft swell from the west, but a fresh onshore wind from the NW (22 mph) makes it messy and lumpy. The combined energy is strong (1352), but the wind is just wrong for clean waves. That pattern sticks around through Wednesday 2nd and Thursday 3rd September—swell hangs in the 5ft to 6ft range, but cross-shore winds keep things choppy and uninviting.
Friday 4th September sees a slight uptick: 6ft to 7ft of west swell, still cross-onshore, and the energy climbs to 682 by the afternoon. Not great for paddling into, but if you’re desperate, it’s there. The real glimmer happens on Saturday 5th September morning. The wind swings offshore from the NW at 12 mph, and we get a 6ft swell from the WNW with a long 12-second period. The combined energy is solid (894), and those offshore winds should clean things up. This is the standout of the whole period—clean, punchy waves with good shape, but it’s a bit much for beginners at that size. Know your limits.
After that, things drop off. Sunday 6th September morning is surfable but very ordinary—3ft west swell, clean with light winds, but it’s small. There’s a long gap of small, marginal or poor surf until the middle of the second week. Then Monday 14th September morning sees a 6ft west swell rolling in with a 10-second period, and combined energy shoots up to 1263, but the wind is cross-onshore and light, so it’s marginal and questionable. By Tuesday 15th September, we’ve got a big 8ft to 10ft west swell, but with strong cross-shore winds (22-25 mph) and lumpy conditions, this is only for experts—and even then, it’s a battle. The energy is massive (1848), but the wind kills the quality.
Overall, the best bet is Saturday 5th September morning. The water’s a touch warmer than usual, the swell’s got grunt, and offshore wind makes it the cleanest session in the forecast. Everything else is either too small, too windy, or too messy to get excited about.
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.
