The Lowdown
Alright, grab a cuppa, because I’ve looked over this whole 16-day window for Mablethorpe, and honestly, it’s a bit of a tough one. The waves are just not cooperating. We’ve got a run of small, weak slop and not much push behind it. The first real chance at anything rideable doesn’t show up until Saturday the 12th of September, and even then, it’s not exactly going to be setting the world on fire. Before that, from now through to Friday the 11th, it’s basically flat with tiny, short-period bumps. You’re looking at a stretch of around 7 days with nothing to get excited about.
The best of a quiet bunch looks to be Saturday the 12th of September. The morning session will see a small northerly swell at about 3ft, but the period is a short 7 seconds, so it’ll be a bit jumbled. The wind will be a cross-offshore from the northwest, keeping the surface reasonably clean. Energy is still weak though. By the afternoon, the wind swings onshore from the northeast, so it’ll get a bit bumpy with ripples.
Sunday the 13th brings a similar story. There’s a little more size, pushing 3ft from the north in the morning, but again, a short 7-second period. The north-northeast wind will be blowing cross-shore, creating a bit of a chop. The combined energy shows a moderate number, which is the best we’ll see, but the quality isn’t there.
To be honest, this setup is more interesting for kite surfing than paddle surfing. The consistent offshore winds through the first week will groom the water, but there’s just no swell to work with. For the few days around Saturday and Sunday with a touch of height, the short period means it’s going to be fat and crumbly, best for a beginner on a foamie if you’re desperate to get wet. Crowds are only a “sometimes” thing, so you’ll have plenty of space. It’s a fairly exposed beach break, but with these tiny waves, that doesn’t mean much.
The water temperature anomaly isn’t flagged, so it’s about average for this time of year. Look, the long-range stuff into the second week (from the 14th onwards) just drops off again into tiny, weak junk. It’s a blank run for sure, but for an area like this, that’s not unheard of. Forecasts change, but right now, there’s nothing to drive for.
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.
