The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough one for Mablethorpe. We’re looking at a 16-day window that’s pretty much a write-off for any proper surf. The first decent recommendation doesn’t even pop up until about a week in, and even then, it’s a real struggle. There’s a long, dry gap from the start through to the middle of the period with nothing worth paddling out for.
The only faint glimmer, and I mean *faint*, comes on Wednesday, 12 August. The morning has a bit of swell, pushing 3ft from the ESE, but it’s a short, weak period of 5 seconds and the combined energy is a measly 52 (weak). The wind is cross-onshore, so it’s going to be a choppy, messy affair. It’s a beginner-level break that’s inconsistent and only "fairly exposed" to the north, and this ESE swell is not the direction it wants. This is a spot for the absolute die-hard who just needs to get wet, not for any kind of quality wave.
The afternoon of that same day sees the swell size bump up to 4ft, still from the ESE with a 6-second period, and the combined energy hits 97 (still weak). But the onshore wind picks up to a fresh 18 mph from the ESE, making it a complete mess. At that size with that wind, this beach setup is more interesting for a kite surfer than a paddle surfer.
Honestly, the rest of the fortnight is a parade of flat, tiny, or onshore slop. The wave heights rarely get above 2ft, and the wind is nearly always junk. There’s a moment on Friday morning, 14 August, with glassy conditions, but the swell is a pathetic 0.7ft. You’d be floating. For an inconsistent spot like Mablethorpe, this kind of blank run is unfortunately pretty normal. The forecast can change, but right now, there’s nothing to get excited about.
Stay patient,
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.
