The Lowdown
Alright folks, Rusty here. Let’s get into it for this stretch of coast.
Honestly, I’m looking at a pretty grim picture for the next 16 days. This is one of those runs where you might be better off cleaning the wax off your board or just taking the dog for a walk instead. There’s practically no surf to get excited about, and the rare moments that look half-decent are still pretty ordinary.
The first bit of hope, if you can call it that, shows up on Saturday the 12th of September, but it’s a long wait. Up until then, we’re looking at a solid 8 day gap with nothing worth paddling out for. From Thursday the 3rd right through to Friday the 11th, it’s all tiny, weak swell with poor surf conditions. The water temp is running 66°F, which is much warmer than normal for this time of year—over five degrees above average—which is very unusual. But that’s about the only highlight.
Now, Saturday the 12th of September morning is your *only* real window here. At Mablethorpe, we finally see a little pulse of swell push up to 3 ft from the NNW. The energy is still very low, sitting at (75), but it’s the most we’ve got on the cards. The wind is light from the NW, keeping it clean, which is a major positive. It’s not going to be anything flash—just surfable waves but very ordinary conditions—but if you’re desperate for a paddle and can manage the inconsistency of this break, it’s the only game in town. Keep in mind it’s a beginner-friendly spot that’s inconsistent, and crowds are possible. The swell period is short at 7 seconds, so expect fat, weak little shoulders rather than any real punch.
After that little blip on the 12th, it goes right back to nothing. Sunday the 13th offers a tiny 2 ft wave but it’s messy with cross-onshore wind. And then from Monday the 14th all the way through to Friday the 18th, we’re talking about ankle-snappers at under 1 ft. The wind does go offshore at times, and we even get a couple glassy afternoons on the 14th and 15th, but with no swell to push, it’s flat.
Sorry folks, this is a proper dud. Stick a pin in Saturday morning the 12th if you’re really jonesing, but otherwise, give it a miss.
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.
