The Lowdown
Alright, let’s get real about Mablethorpe.
Honestly, this outlook is a tough one. For the next week and a half, the surf is just not playing ball. The first proper pulse of energy doesn’t show up until Tuesday the 16th of September, and even then, it’s not looking great. The wind is blowing hard onshore and cross-shore, making the surf messy and lumpy. You’re looking at a flat spell with barely a ripple until then.
Now, we do get a bit of a lift around Thursday the 17th of September. The swell bumps up to around 4ft, but it’s coming from the NNE, and the period is short at 6-7 seconds. That’s weak, windswelly stuff. The energy reading is moderate, about 111, so there’s something there, but the quality is pretty ordinary. Winds are light and cross-off, so it will be clean. But honestly, it’s not going to set your world on fire.
The best of a pretty drab run hits on Friday the 18th of September. Mablethorpe sees 4ft of swell from the same NNE direction, with a similar short period. The combined energy is 112, which again is moderate. The morning is your best bet with light SSW winds and clean conditions. This is where I’d point you if you’re desperate for a paddle. It’s small, it’s weak, but it’s ridable. Just don’t expect any barrels.
Beyond that, it drops right back off again. The second week is a washout with tiny swell and strong, offshore winds that will blow the little bumps flat. There’s a lot of nothing on offer here.
Keep in mind the water is a very unusual 65°F at the start. That’s much warmer than normal for this time of year.
Bottom line: if you’ve got to get wet, Friday the 18th morning is the least worst option. Otherwise, save your energy.

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.
