The Lowdown
Alright folks, Rusty here. Let's be straight with you – it’s a tough stretch ahead for the Mablethorpe area. The whole 16-day window looks pretty grim for a proper paddle session.
We’ve got a massive gap right from the start. There’s no surf worth mentioning until almost two weeks in. The first few days show nothing but tiny, weak slop, if that. The water temp on the 10th is sitting at 65°, which is a solid 6° warmer than usual for this time of year – that’s very unusual, but it doesn't make the tiny waves any better.
The standout moment, if you can call it that, falls on Thursday, September 24th. For the morning, we see a little pulse that grabs some energy, but the afternoon is the only real blip on the radar. The swell picks up to 3ft from the north, with a moderate energy reading (212). Problem is, the wind is onshore from the ENE at 6 mph, which is gonna mess it up. It’s a small window of hope but honestly, the quality is rated poor.
Before that, on Wednesday, September 16th afternoon, there’s a brief moment. We get a 3ft north swell with 76 energy, but it's a short 6-second period and a cross-shore wind. You might get a few gutless closeouts, but don’t hold your breath.
Looking at the end of the run, Thursday the 24th into Friday the 25th is the only time the combined energy even hits three digits. The 24th afternoon has that 3ft north swell (212 energy), but with onshore wind it’s more of a mess than a surf. Friday the 25th morning cleans up a bit with a light cross-shore breeze and a 2ft north swell (63 energy), but it’s still tiny.
Honestly, for Mablethorpe (England), this is a brutal 16-day stretch. The winds are mostly cross-off or cross, which keeps the surface okay, but there simply isn't any proper swell to work with. You’re looking at a solid two-week dry spell before anything even registers. Sometimes the hook-up just doesn’t come through. Forecasts can change, but for now, save the wax.
Keep your eyes on long-range charts, but I wouldn't cancel any plans for this.

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.
