The Lowdown
Alright folks, Rusty here. Let's be straight with you – the outlook for this next stretch is a tough one. We're looking at a 16-day window that is, for the most part, a write-off for any decent surf. The water's sitting at a very unusual 67°, which is a good 5° warmer than normal for this time of year. That's a talking point, but it’s small comfort when the waves just aren't cooperating.
The forecast starts with a bit of a dud and stays that way for a long time. From Wednesday the 12th right through to the end of the month, every single session at Lynmouth is flagged as "poor surf conditions." The bulk of the first week is a bust. There's a brief moment on Thursday morning the 13th where the wind goes glassy with a 2ft swell from the WSW showing 117 units of moderate energy, but the quality is still marked as poor. It's a tease. The energy level is simply too weak and the wind too inconsistent to make anything of it. For the most part, week one is a total flat spell or blown out mess.
The second week, from the 19th onwards, brings a little more swell energy – we see a few days with combined energy readings in the 100-170 range, which is moderate. But the wind is the killer. It's mostly cross or onshore, and often strong, making for lumpy, choppy, and messy conditions. The swell direction is consistently from the W or WNW, which is not the optimal WNW that Lynmouth (a sheltered point/river) prefers. It's inconsistent here, and when it does show up, it's not clean.
Given the light winds and clean conditions alongside some of the larger swell pulses, this setup is frankly more interesting for kite surfing than paddle surfing. The strong cross-onshore winds on the 20th of August, with 4ft of swell, will be a windy mess for surfers but a playground for the kite crowd.
There are no standouts. The best you can hope for is a very average, weak, and probably blown-out wave. Hold tight, and keep an eye on the charts – things can change, but for now, the bag is staying dry.
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.
