The Lowdown
Alright folks, Rusty here. I’ve had a good look at the charts for the Mablethorpe stretch, and I’ve got to be straight with you – it’s looking flat, and it’s going to stay that way for a while. There’s a big, long gap of nothing on the cards before we even see a whisper of a wave worth getting wet for.
The first surf I can even talk about is a tiny pulse of 1ft from the ESE on Wednesday, the 12th of August. The problem is that’s coming with a rubbish onshore wind and a weak period of just 5 seconds. The combined energy is a weak 80 (moderate energy), but the wind will make a mess of it. That’s not a surf day, that’s a day to walk the dog.
Things get a little more interesting into the afternoon of Wednesday the 12th. The swell bumps up to 5ft from the ESE, with a combined energy of 169 (moderate wave energy). But again, the period is a short 6 seconds, and it’s coming straight onshore from the East at 25 km/h. For a beach break like this, that’s a choppy, blown-out mess. Honestly, with that swell size and the strong onshore wind, it’s looking more like a kite surfing setup than a paddle surfing one. This one’s for the experts only if they’re desperate, but it’s not a standout.
The water temperature is sitting at 68°, which is a whopping 7° warmer than normal for this time of year. That’s very unusual.
After that, the swell drops straight back off again. The 13th of August has a clean 2ft from the East with a light offshore wind in the morning, with a combined energy of just 25 (weak energy). It’s clean, but there’s no real power. You’ll be on a longboard doing the walk of shame back to the car.
The rest of the 16-day window is a total write-off. We’re looking at tiny 0.3ft to 2ft slop, mostly from the North, with inconsistent periods and a mix of cross and onshore winds. There’s no stand-out day, no big groundswell, nothing to get excited about. The finder is showing nothing but poor surf conditions for every single session. It’s a grim run, and it’s normal for this area when the North Sea goes quiet.
Keep the board in the car, check the forecast again in a few days, but for now, I wouldn’t bother.

Information about the Mablethorpe Surf forecast
The above surf forecast table for Mablethorpe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Mablethorpe can be found by selecting the local surf guide option on the grey menu. Our Mablethorpe 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 (Mablethorpe) 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 Mablethorpe 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.
