The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook is a tough one. We’re looking at a 16-day window starting now, and honestly, the surf is pretty much a no-show for the whole stretch. There’s a big gap right from the get-go with nothing worth paddling out for.
We’ve got one spot on the radar, Mablethorpe, but it’s a real struggle. The first sniff of anything comes on the 7th of September, with a tiny 0.7ft north swell. The combined energy is a weak (6), and it’s just not enough to get excited about. The water is a notable 65°, which is 6° warmer than usual – very unusual for this time of year, feels like a warm bath. The wind is offshore, so it’s clean, but there’s barely a ripple.
The pattern doesn’t improve. Consistent, weak, small swells from the north and north-northeast keep rolling through with heights mostly under 2ft. The energy levels are all in the single or low double digits – the highest we see is a 4ft north swell on the morning of the 9th of September, with moderate energy (185), but the wind swings onshore and it’s blown out. The wave comment says “poor surf conditions” for every single entry. Even the small windows of offshore wind can’t save it because there’s just no wave to work with.
Mablethorpe is an inconsistent spot, and this forecast proves it. It’s rated as a beginner wave, but honestly, with nothing on offer, even a beginner would be sitting on a flat sea. For the more experienced lot, there’s zero to chase. The setup is a beach, and with the wind we’ve got, it’s a non-event for paddle surfing.
The only real standout here is the lack of surf. It’s a blank run for the whole 16 days. Don’t hold your breath, but forecasts can change.
Stay tuned, 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.

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.
