The Lowdown
Alright folks, Rusty here. Let’s have a look at what the sea’s got cookin’ for us at Lynmouth. Gotta be straight with you, it’s a bit of a tough stretch ahead, so let’s break it down.
We’re looking at a quiet start overall. The first recommendation doesn’t pop up until later, so there’s a long gap of over a week with nothing you’d want to paddle out for. The water is sitting at 66°, which is much warmer than normal for this time of year – a solid 5° above average, so that’s a real treat when you do get in.
Right, the first real glimmer of hope comes on Wednesday the 23rd of September. It’s not a standout by any means, just a marginal call. We’ve got a solid 7ft to 7ft swell coming from the west with a period of 8 seconds. That’s over 8ft, so this is strictly for the experts out there – too much grunt for beginners. The combined energy is strong at 513, jumping to 612 that afternoon, so there’s plenty of water moving. The trouble is the wind is light but cross-onshore, so it’ll be a bit bumpy. It’s a point/river setup at Lynmouth, and with this west swell and a bit of size, it could have some shape, but don’t expect perfection. This is a rare break that’s listed as inconsistent, so seeing any size here is notable, but crowds are often an issue, so be prepared to share the take-off zone.
Then on Thursday the 24th of September, things look a little tidier for the morning. The swell drops to 5ft from the west with a period of 8 seconds, combined energy is still strong at 442, but now the wind is cross-offshore from the east, which will clean the faces right up. This is the best on offer in the whole window. It’s not huge, but 5ft of west swell with clean, glassy conditions makes for a fun, manageable wave for the experienced crew. It’s still too big for beginners though, at over 5ft. The water will still be warm from that anomaly, so it’s worth the wait.
Honestly, that Thursday morning slot is the one to aim for. The rest of the outlook is littered with poor conditions, strong winds, and messy surf. The 23rd has size but dirty wind; the 24th morning has the quality. After that, it fizzles out again into small, weak, or messy surf right through to the end of the 16-day run.
Stay patient, get that Thursday morning session in, and don’t get too excited about the rest.
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.
