The Lowdown

Gap from now until the 19th of August with no real surf on offer. It’s flat, small, and chopped up for days. We’ve got a weak Westerly bump coming mid-period, but the wind’s all over it. Looks like we’ll have to wait for Wednesday morning to get anything half-rideable, and even then, it’s a struggle.

Wednesday the 19th sees the swell start to build a bit, pushing 4ft out of the West with a 7-second period. The energy is still weak-to-moderate at best, with the combined swell energy at 150, and it’s cross-shore and lumpy. Not pretty. But Wednesday afternoon turns slightly cross-offshore from the WSW, cleaning it up a little. That’s the first real window, but it’s still only marginal.

Thursday the 20th morning has a bit more push in the water, 4ft West swell, energy up to 181, but it’s still cross-shore and messy. Too much wind to be any good.

The standout of this whole sorry stretch is the 29th of August. The swell jumps to 7ft out of the WSW with an 8-second period, and the energy rockets up to 650. That’s a serious pulse of energy, a real strong push of water. The wind is howling cross-shore though, fresh and lumpy. Lynmouth (North Devon) is a point/river setup, so a longer period works better here, but 8 seconds is short and punchy, and with this much wind, it’s going to be a full-on, expert-only session. It’s also inconsistent, so you’ll be scratching around for sets. If you’re an advanced surfer, that’s your one real shot, but be prepared for a beating.

Before that, the 20th through the 28th is mostly poor. There’s a few small, clean-ish windows—like the 21st with lighter winds and a small 2ft West swell—but it’s all cross-on and junky. The 24th afternoon goes glassy with a tiny 0.3ft, which is just flat. The 27th has a moderate 4ft West swell but it’s still onshore and choppy.

The water is running much warmer than normal for this time of year, well above average, so you won’t need a thick suit.

After that big pulse on the 29th, it settles back down to 4ft with heavy cross-shore winds for the 30th and 31st. The last day of the month has some cross-offshore wind in the afternoon, but the swell is dropping and it’s still not worth getting too excited about.

Bottom line: one day to really watch—Saturday the 29th—and it’s only for the experienced. Everything else is a wash. The inconsistency of this break is a big factor; it’s a spot that doesn’t fire often, and this forecast isn’t changing that story.

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.
