The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this is a tough one. The 16-day window for Mablethorpe is a real challenge. We've got a long stretch of very small, weak surf, and the scoreboard is pretty much empty. The good news is the wind is often offshore or light, so when there's a ripple, it'll be clean, but the problem is there's barely any energy to work with. The combined swell energy is stuck in the low single and double digits for most of the run, just a whisper of a wave.
Let's break it down. From Thursday, August 6th, right through to the end of the forecast, every single period is rated as "poor surf conditions." For the first several days, the swell is tiny, around 1ft to 2ft, with a short period of 7 to 8 seconds, meaning weak, mushy waves. The wind does offer some clean windows, like the offshore wind on Thursday morning and the glassy conditions on Sunday morning, August 9th, but with a swell of just 0.3ft and combined energy of 3, it's flat, not surfable. You'd be better off with a paddleboard or a cold drink.
The middle of the week brings a slight bump. Into Wednesday, August 12th, the swell gets up to 3ft from the ESE with a period of 5 seconds, giving a combined energy of 60. That's the biggest we'll see, but it's a short-period, weak windswell, and the wind is onshore. It'll be a choppy, bumpy mess, more interesting for kite surfing than a proper paddle session. The setup is a beach break, so that onshore wind will just ruin it.
Later in the run, we see a return to cleaner winds. Friday morning, August 14th, has a light offshore breeze and a 2ft swell, but the energy is only 15. And then into the final week, from the 20th onwards, the offshore winds return, with a consistent WNW flow. The swell stays tiny, mostly 0.3ft to 1ft, but the wind is clean. The 21st of August has a fresh offshore breeze and a 1ft swell with a combined energy of 15. It's not going to be a classic, but if you're desperate for a longboard or a foil, that's the cleanest window to try and catch a dribbler.
Honestly, for this part of the coast, a blank run like this happens. The inconsistency is a normal thing. The surf is just too small and weak to justify a session. Keep an eye on the charts, but for the next 16 days, the best plan is to find another hobby or wait for the next proper groundswell.
Rusty.

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.
