The Lowdown
Alright, I’m lookin’ at this Lynmouth stretch, and I gotta be straight with you—it’s a tough one. This is a point/river setup, takes a certain swell direction to fire, and for the next two weeks, well, it’s mostly a whole lot of nothin’. We’re talkin’ a long, dry spell with hardly any rideable waves, so don’t get your hopes up.
We start off on Wednesday, August 5th, with a bit of a tease. There’s a 4ft swell from the west, but the period’s a short 6 seconds, and with a stiff 22 mph cross-wind, it’s just a mess. The water’s a warm 67°, which is *much warmer than normal* for this time of year, more than 3° above average—that’s a real oddity. But the surf? Total dud. The combined energy’s weak, just 94, and it gets a little better in the afternoon with 5ft and 183 in energy, but the wind is still howling. No good.
Thursday and Friday stay flat and choppy. By Friday morning, August 7th, it’s glassy with a 0.7ft wave, but that’s a lake, not a surf. The weekend and into the next week are the same story—tiny, weak swells, mostly cross-onshore wind, and no power. The combined energy stays under 100 for days on end. There’s a stretch from the 5th right through to the 16th where you’re just not gonna get a wave worth paddling for.
Then, hold on. Monday, August 17th, we get a big pulse. 10ft swell from the west, 11-second period, and the combined energy jumps to 2388—that’s serious power. But here’s the catch: the wind is a fresh 19 mph cross-onshore, and that’s gonna make it lumpy and messy. For a spot like Lynmouth, that’s a lot of water, and it’s gonna be a wild, blown-out mess. Definitely only for experts. The afternoon drops to 8ft with a cross-wind, but still ugly. After that, it fades fast back to nothing.
So, the only standout, and I mean the *only* one, is that Monday, August 17th swell. It’s a big, powerful groundswell (a long 11-second period), and if you’re an advanced surfer and you don’t mind strong, lumpy conditions, there might be some heavy, raw energy to chase. But the quality’s poor. Don’t expect a classic day. For the rest of us, it’s a waiting game. Forecasts can change, but right now, it’s a long, quiet stretch.

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.
