The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next couple of weeks are looking pretty grim for a paddle. We’re talking about a long stretch of tiny, weak energy that just won’t get it done. The first real sign of life doesn’t show up until the 21st of September, so we’ve got a solid two-week gap with nothing worth getting wet for.
Mablethorpe is the only game in town, and for the first two weeks, it’s a write-off. The water here is about average for the time of year, nothing unusual. From Monday the 7th through to the 20th, the heights are mostly between 0.3 ft and 2 ft, with a brief, messy bump of 5 ft on the 9th that’s still just poor quality. The combined energy on most days is a pathetic 1 to 10 (weak), and even the bigger day on the 9th only hits 239 (moderate). The winds are often offshore or clean, but with zero swell to work with, it’s just a flat, pretty lake. Not a single wave worth mentioning.
Now, if you’ve got patience, the 21st of September Monday morning is your one and only standout. We’ll see a proper pulse of 7 ft swell from the north with a decent 10-second period, and the combined energy ramps up to 1348 (strong to very strong). The wind is a fresh offshore from the west, which should keep things clean. But listen, that’s a big wave for a beginner – over 8 ft is expert territory, so this is for the experienced crew only. The afternoon drops to 4 ft, still clean but with less energy (353). Even with that little bump on the 22nd, it’s back to nothing. That Monday morning is the only real chance in the whole 16-day window, but it’s two weeks out, so keep an eye on it.
Rusty, signing off.

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.
