The Lowdown

Alright, let’s talk about Lynmouth. Honestly, it’s a tough stretch ahead. This is a sheltered point and river mouth setup, and it’s inconsistent at the best of times. For the next couple of weeks, the swell and wind just aren’t lining up to give us anything worthwhile. The water is sitting at a very unusual 68°, which is much warmer than normal for this time of year, but that’s about the only positive.

Right out of the gate, Monday the 17th has some small 2ft swell from the west, but it’s got a short period of 6 seconds and a cross-shore wind that’s messing it up. Combined wave energy is weak at (37). It’s a write-off. Tuesday the 18th sees a bit more size, 4ft, but the wind swings cross-onshore and it’s choppy. No good. This pattern of poor conditions, with onshore or cross-shore winds and short-period, weak swell, just keeps rolling through the rest of the week and into the next. The swell height stays mostly under 3ft, and the energy is low.

We hit a real flat spell from the 22nd through the 24th. Swell drops to 0.7ft or 1.0ft, with energy numbers as low as (5) to (19). It’s barely a ripple. There is a moment on Monday the 24th morning that’s glassy, but with only 0.7ft of swell, it’s not surfable.

Things start to look a little more interesting towards the very end of the run, but the conditions are still poor. On Friday the 28th, we get a bit of a pulse with 5ft swell from the west, and the wind goes cross-offshore, cleaning it up. The combined energy jumps to (239), which is moderate, but the period is still short at 8 seconds. That afternoon is similar, with 4ft and energy of (246). It’s cleaner than anything we’ve seen, but it’s not great.

Saturday the 29th picks up to 5ft from the west, but the wind turns back cross-onshore and it gets lumpy. The energy is strong at (364), but the quality is gone. Then on the 1st of September, we see the biggest swell of the whole forecast, 7ft to 8ft from the west, with combined energy hitting (670) and (631). That’s serious energy. The wind is cross-offshore again, so it’ll be clean. But at that size, and with a short 8-second period, this is strictly for experts at a tricky spot like Lynmouth. It’s going to be heavy and fast.

So what’s the best on offer? Honestly, there isn’t a standout. The cleaner windows on the 28th and the 1st of September are the only times it’s even worth a look, and even then, it’s more about the power than the quality. If you’re a seasoned local who knows the river mouth, the 1st of September morning might have some raw, powerful waves, but it’s not for the faint of heart. For everyone else, this is a long, flat, and poor run.

Stay patient, lads. The forecasts can change, but right now, Lynmouth is keeping its cards close to its chest.

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.
