The Lowdown
Alright, this is Rusty. Let me level with you. Lookin’ at the charts for Lynmouth, it’s a rough stretch. There’s a lot of wind and messy conditions on the cards for the next couple of weeks. The water is sittin’ at 67°F, which is much warmer than usual for this time of year, a proper anomaly. But that’s the only gift. The first real window of opportunity doesn’t show up until Monday, 14 September.
Let’s start with the bad news. From now, right through the first week of September, it’s a write-off. The wind is howlin’ from the west and northwest, mostly cross or cross-onshore, makin’ the already poor surf conditions a total mess. We’re seein’ a bit of swell around 5ft to 6ft on the 31st of August and the 4th of September, but the wind is choppin’ it all up. The combined energy is moderate at best, like 472 and 348, but it’s not ridable. Not worth paddlin’ out.
There’s a gap of flat, weak, or messy days from the 1st to the 6th of September. The 6th of September has a clean morning with a light breeze, but the swell is a pathetic 2ft – that’s barely a ripple. The 7th of September shows a pulse of long-period swell (11 seconds) with a combined energy of 267, but it’s on a cross-onshore wind, so it’ll be choppy and unappealin’. The 8th of September is similar – a bit of 4ft swell but cross-shore winds.
The first real standout, and the only one I’d get excited about, is Monday, 15 September. The morning is lookin’ clean with a decent 7ft west swell. The wind is cross-off from the WSW, which is a solid combo for a point break like Lynmouth. The combined energy is strong at 612. This is a good one for experienced surfers only, as it’ll be powerful. The afternoon gets bigger, 8ft, but the wind picks up to a near gale at 31 mph, so it’ll be a morning mission or nothin’.
Tuesday, 15 September, is the same story. The morning is clean with a 7ft swell. That’s your best bet. After that, the swell fades and the wind starts to go cross again.
So, the long and short of it: there’s a lot of waitin’. The best surf on offer is the mornin’ of Monday, 15 September at Lynmouth. It’s an advanced wave, so don’t take it lightly. The 7ft west swell with clean, cross-off winds will be a proper session for the guys who know what they’re doin’. The period is short (8 seconds), so it’ll be a bit dumpy, but the energy is there. The mornin’ of Tuesday, 16 September, is a back-up, but it’s a bit bigger and the wind is a problem.
Stay patient, this ain’t the time for a beginner. The waves are there, but they’re demandin’.
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.
