The Lowdown
Alright, Rusty here. Let’s break down what’s cooking for Lynmouth, and I’ll give it to you straight.
First few days are a total dud. This week and into next, most of the surf is either too small or too messy to get wet for. There’s a big quiet spell – about 10 days – where you’re better off doing something else.
Starting Tuesday the 25th, you’ve got 2ft of weak, short-period windswell out of the ENE, with a fresh 21 mph cross-shore wind. Lumpy and hopeless. Wednesday the 26th to Friday the 27th is clean but tiny – waves barely 1ft, with periods around 7 to 9 seconds. Longboard only, and even then it’s a struggle. Into Saturday the 29th, the swell picks up to 3ft but still with a short period, and the energy is weak. Nothing doing.
The one to keep your eye on is Tuesday the 8th of September. That morning the wind goes glassy – dead calm. The swell is a solid 4ft from the WSW with a really long 15-second period, which is proper groundswell. Combined energy is a solid 671 – that’s moderate to strong juice. For a spot like Lynmouth, a point and river break, that long-period groundswell will wrap in clean and offer some proper lines. The sets will be spaced, but paddling out will be a breeze and the wave shape is going to be miles better than anything else in the window. Just a heads up – with that kind of period, it could get a bit straight at times, but it’s your best bet by far. You’ll need to be a solid surfer to handle the push.
After that morning, it’s back to cross-shore junk and lumpy conditions. The afternoon of the 8th gets ruined by a moderate cross-shore, and Wednesday the 9th is just lumpy cross-chop again.
So bottom line: hold tight, and make sure you’re free on the morning of Tuesday the 8th of September. That’s the one to go for. Everything else is a miss.
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.
