The Lowdown
Alright, Rusty here. Let's get real about what's coming our way.
To be brutally honest, this stretch is a bit of a write-off for us at Lynmouth (point/river) . The water is a weird 67° which is a massive 5° warmer than usual for the start of September – that's very unusual, but it's not going to make the waves any better. The setup just isn't there. The whole 16-day window is looking grim. We've got a long, blank run with nothing worth paddling out for.
Friday 4th kicks things off with a messy 6ft W swell but a 25 mph cross-wind is just shredding it. The combined wave energy is moderate (392) but the wind makes it unsurfable. That theme continues right through the first week. We see a bit of a pulse on Monday 7th – a 5ft to 5ft W swell with a long period of 13 seconds, giving us strong energy (782). The afternoon cleans up with a cross-offshore breeze, which sounds promising, but the data still flags it as poor surf. For a point/river break, a long-period groundswell like that can sometimes break too straight and close out, so even with clean conditions, it's a gamble for experts only. The wind stays strong and cross for most of the week, keeping everything lumpy and choppy.
Monday 14th sees the swell bottom out completely at 0.7ft. We're looking at a big gap with flat, weak conditions right through to the middle of the month.
There is a late flicker of hope. On Thursday 18th September, we get a 5ft to 5ft W swell. The morning looks the best of the whole run with a light 6 mph onshore breeze and a combined energy of 263. It's a short-period swell (7 seconds), so it won't have much push, but the light wind could make it clean and rideable for the few who are keen. Still, the call is poor surf conditions, so don't expect much.
Honestly, this is one of those runs where you're better off doing a board repair or just staring at the horizon. The setup looks more interesting for kite surfing than paddle surfing with all that cross-wind. For now, just wait. Forecasts can change, but right now it's a no-go.
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.
