The Lowdown
Alright, folks. Rusty here. Let’s not sugarcoat it – this is a grim one. The 16-day outlook for Mablethorpe is a long stretch of tiny, poor waves. We’re looking at nearly two weeks of nothing before anything rideable shows up. The water temp is about 66°F... that’s nearly 7°F warmer than usual for this time of year, which is pretty wild to feel, but it won’t help the surf.
Right now, and for the next week and a half, it’s all knee-high slop. Swell heights barely scrape 2 feet, and the combined energy figures are stuck in the low double digits (like 2 to 28). The wind does go offshore from the west a few times, especially Thursday morning and Friday, but there’s just no swell to work with. It’s clean, but it’s a flat glass of water. You’d be better off with a kiteboard on those windy days.
Finally, on Wednesday the 9th of September afternoon, we get a glimpse of something. A 3-foot swell from the north with a period of 10 seconds pushes the combined energy up to 146 – that’s moderate energy, finally. The wind is offshore from the WSW at 15 mph, keeping it clean. The wave comment says “surfable waves but very ordinary conditions,” and honestly, that’s the best we’re gonna get. For a beginner spot that’s inconsistent, this is your window. It’s not a standout, but it’s the only window.
After that, it’s back to tiny or flat conditions through the 17th. The combined energy drops to zero on the 15th and 16th. There’s a moment on the 16th afternoon with glassy conditions, but it’s a 1-foot, 4-second windswell from the south – basically a ripple. No good.
So, the only real pick here is Wednesday the 9th of September afternoon at Mablethorpe. It’s a north swell, 3 feet, with a 10-second period, and offshore west-southwest wind. It’s surfable, but don’t expect any barrels. The break is inconsistent, so you’ll be waiting for those sets. Get on it if you’re desperate, but temper your expectations. Crowds are possible, but with this outlook, I doubt many will show. Rusty out.

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.
