The Lowdown
Right, grab a cuppa, because the next couple of weeks are a bit of a tough watch. The honest truth is there's not a single recommendation in the 16-day window. We're looking at a flat spell with no decent surf on offer for most of that time. The only flicker of life comes right at the tail end, but it's not something to get excited about, so I'll cover that briefly.
Overall Pattern
For the vast majority of the forecast period, from now through to the 26th of September, the surf is basically non-existent. We're talking days on end with tiny, weak dribble that just isn't worth paddling out for. The energy levels are pathetic, mostly single or low-double digits in terms of combined wave energy, so you're not missing a thing. The consistent north-northeast fetch that we'd hope for just isn't happening.
The Long Wait (Now - 27 September)
There's a massive gap. Nearly two weeks of nothing. The first decent pulse of energy shows up around the 27th of September, but even then the conditions are poor. The wind is a messy cross-onshore from the north-northeast, chopping it all up. The swell height just cracks 3 ft with a period of 6-9 seconds, meaning a weak, jumbled windswell. It's a complete write-off for a proper surf.
The Late Blip (28 - 29 September)
Alright, so on Monday the 28th of September and Tuesday the 29th, we finally get some size. The swell builds to 4 ft to 5 ft from the north-northeast, and the wave energy jumps to 233 and then 442 (moderate). But before you get your board, the wind is still a problem. It's a persistent cross-onshore and cross-shore breeze from the NE and NNE, making for a choppy and cross-chop mess. The period is short, around 8 seconds, so the energy is messy. This is really only going to be any fun for a big-wave crew with a lot of paddle power, and even then, it's going to be a battle. For the average punter, it's a pass. The water temp is a very warm 64 °F, which is 5 °F warmer than normal – that's a notable anomaly, but it won't help the wave quality. This setup at a spot like Mablethorpe, which is a fairly exposed beginner spot and inconsistent at the best of times, with the wind howling cross-shore, looks far more suited to kite surfing than a proper surf session.
The Final Day
The very last day, Tuesday the 29th, shows the swell dropping back to 2 ft to 3 ft with an easterly wind. Still poor. It just fizzles out.
Look, it's a proper dry spell. The spot is inconsistent at the best of times, and this run is a clear example of that. Keep the board in the bag and don't hold your breath. Forecasts can change, but for now, it’s a quiet one.

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.
