The Lowdown
Right then, let’s have a look at what’s cookin’ for Lynmouth over this sixteen-day stretch. Straight up, I gotta tell you, it’s a grim one. The whole window from now right through to the end is what I’d call a write-off. Not a single session worth paddling out for. The first surfable possibility doesn’t even appear, and the gap is the entire 16 days – that’s how flat and messy it’s lookin’. This ain't unusual for a sheltered spot like this, but it doesn’t make it any easier to swallow.
For a place that needs a solid WNW groundswell to work, there's just no push. The combined energy of all swells directed here barely ever gets into double digits, peaking at a weak 103 on Thursday the 13th afternoon, but even that’s with a cross-shore wind hitting 22 mph.
Water temp on the 9th is sitting at 67°F, with an anomaly of 5°F above normal – that’s way warmer than usual for this time of year, which is a little weird but not gonna help the waves.
You might see the odd day with a touch of clean wind, like Tuesday morning the 11th with cross-offshores, but the swell is a pathetic 0.7 ft from the west with a short 8-second period. Not enough to stand up on. Wednesday the 13th afternoon has a brief moment where the swell hits 2 ft and the wind goes offshore, but the energy is still poor and the period sits at 10 seconds – not enough grunt for a point break setup. That’s the best of a bad bunch, but it’s still a no-go.
Everything in this forecast is marked “poor surf conditions” with a score of zero, and the wind is either cross, cross-on, or just too strong. By the time we get to Saturday the 22nd, there’s a bit of cleaner cross-off wind and a tiny 2 ft NW swell with a dismal 5-second period – a complete non-starter.
Bottom line: don't bother waxing up. This is a classic case of no swell, bad angles, and messy wind. Forecasts can change, but right now this stretch is a long blank run. The only thing that might be worth watching is if a bigger groundswell pops up out of nowhere for the second week, but as it stands, save your energy.
Stay salty.

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.
