The Lowdown
Alright, crew, let’s have a look at the charts for our region. I’ll be straight with you – this is one of those outlooks where you might want to keep the board in the bag for a good long stretch. The whole 16-day window is a tough one, with hardly any real quality on offer. We’ve got a long gap of poor conditions right from the start, and it doesn’t really let up. Let’s walk through it.
We kick off on Wednesday the 16th of September, but there’s nothing to get excited about. We’re looking at tiny waves, with swell heights around 0.3ft to 1ft from the north, and the combined energy is barely registering – just a 2 in the morning. The wind is a mix of cross-off and glassy at times, which would be nice if there was any swell to ride. But there isn’t. This flat, weak pattern runs right through the rest of the first week. The swell stays under 2ft with combined energy rarely getting above 34, and winds are either cross-off or offshore, but it’s all just poor surf conditions with nothing to push you along.
The following week doesn’t bring much hope, either. From Sunday the 20th through to the end of September, we see a few pulses of slightly bigger swell, but nothing that breaks the “poor” rating. On the 25th of September, Friday, we get some 2ft to 3ft from the north-northeast, but the period is short – 4 to 5 seconds – so it’s weak and choppy. Combined energy around 44 in the afternoon, but the wind is a moderate cross-shore, which just messes it up. This is not a setup for a good paddle session.
The only period that looks slightly more interesting, and I mean *slightly*, is around the 27th of September, Sunday. We have a bit of a longer period swell arriving: 2ft from the north, with a 12-second period in the morning and 11 seconds in the afternoon. The combined energy climbs to 109 and 105, which is moderate energy for a change. The wind is light cross-onshore, so it’s not glassy, but it’s not howling either. For Mablethorpe, this is a small, weak groundswell. It’s not for beginners – the 2ft is manageable, but the long period means it might straighten out on this beach setup. You’d want a point break or reef for that kind of swell, but here, you’re looking at a tricky paddle for very small waves. This is the closest we get to a standout, but it’s a real long shot.
After that, we head into the first of October with a bit more size: 4ft from the north-northeast on Thursday morning, with combined energy at 127. But the period is short at 7 seconds, wind is light cross-shore, and it’s still rated as poor. That height is okay for intermediates, but the quality just isn’t there.
Overall, this is a grim run for Mablethorpe. The beach is exposed to the north, which is where most of the tiny swell is coming from, but the energy is weak for almost the entire 16 days. There’s no standout break here – nothing that gets the heart racing. If you’re a kite surfer, you might get some use out of the stronger cross-shore winds on the 28th and 29th, but for paddle surfing, it’s a long wait.
Keep an eye on the charts, but for now, it’s a lot of staring at flat water.

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.
Mablethorpe is 20 km (12 miles) from Skegness. If you plan a holiday in Lincolnshire, look for hotels and other accommodation in Skegness. Skegness has rooms for a wide range of budgets as well as car hire and transport links.
