The Lowdown
Alright, let's talk in feet and miles per hour. I'm Rusty, and for Lynmouth, it's a pretty bleak 16-day picture. We're looking at a whole lot of flat spells and onshore junk.
The swell is tiny. We kick off on Tuesday afternoon with a 0.6ft west swell, and it barely gets a pulse going. The wind is mostly a problem, swinging from cross-off to cross and cross-on, keeping things choppy. The water is a warm 67°, which is much warmer than usual for this time of year, but that's the only highlight. The combined swell energy is weak, barely cracking 34 (34 units) on the best of the early days, and often sitting in the single digits.
There's a gap of basically nothing worth mentioning from the 11th all the way through to the 25th of August. You'll see a few moments where the swell height nudges up to 2ft, but the period is short, the wind is wrong, and the "poor surf conditions" tag tells you everything. On the 12th, we have a 1ft swell from the WSW with a 10-second period, but a 16 mph cross-shore wind makes a mess of it. The 13th sees a 2ft swell, but again, the wind is on it. A few glassy mornings pop up, like the 16th and the 18th, but the swell is so small—1.0ft and 2ft respectively—you'd be lucky to get a ripple.
Then, right at the very end of the forecast, on Wednesday the 26th of August, things finally change. The wind goes light and clean. Wednesday morning brings a 4ft west swell with a 6-second period and a light ESE cross-off breeze. The energy finally shows up at 156 (156 units). It's described as "surfable waves but very ordinary conditions," which is a step up from "poor." Then Wednesday afternoon, we get glassy conditions with a 6ft west swell, an 8-second period, and a massive jump in energy to 320 (320 units). That's the one to keep an eye on.
Now, the standout is clearly that Wednesday afternoon on the 26th. The 6ft swell is the biggest we've seen, and with glassy conditions, it's going to be clean. But, I gotta be straight with you. Lynmouth is an advanced, inconsistent point and river break that's sheltered from the WNW swell. It's also a spot that's *often* crowded. For a 6ft wave, that's a solid size, and with the period only being 8 seconds, it's not the long-period groundswell you'd dream of. The size is getting up there, so it's not for the beginners. It's the best on offer, but it's a promise with a lot of caveats so far out.
For the rest of the time, just don't bother. The setup with the wind and small swell is more interesting for the kite surfers than for us paddle surfers. It's a long, dry run, but that's how it goes sometimes around here.
Rusty.

Information about the Lynmouth Surf forecast
The above surf forecast table for Lynmouth provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lynmouth can be found by selecting the local surf guide option on the grey menu. Our Lynmouth 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 (Lynmouth) 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 Lynmouth 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.
