The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the Mablethorpe stretch.
Well, I gotta be straight with you – this is a grim outlook. We're looking at a long, dry spell with barely a ripple worth paddling for. The first week is a write-off. There's a little pulse of energy that shows up on Wednesday the 9th, but it’s just not enough to get excited about. The real problem is the persistent offshore wind, which is clean, sure, but it's flattening out any chance of a proper wave.
From Friday the 4th all the way through to Tuesday the 15th, the wave heights are mostly under 3 ft, and the combined wave energy is weak, sitting way below 100 for most of that time. The water is a balmy 66°F which is much warmer than normal for this time of year, which is a real tease. The swell is coming from the north, but the period is short, mostly between 6 and 9 seconds, so it's just weak, windswell mush.
Now, there is a standout in the second week, but it's a long way off and I'm cautious. Saturday the 19th of September shows a bit of a lift. The swell pushes up to 6 ft from the north, with a period of 8 to 9 seconds. The combined energy jumps right up to 382 to 435 (strong energy), which is a real eye-opener after all this nothing. However, the wind is cross-onshore from the northeast and east-northeast, which is going to chop it up. For a beginner spot like Mablethorpe, 6 ft is pushing it, and with that wind, it's going to be a messy, bumpy mess. Honestly, those conditions look more interesting for a kite surfer than a paddle surfer.
So, the long and short of it is: there's no good surf on offer in the 16-day window. The first week is a total flat spell, and the only pulse of real size in the second week comes with poor wind. It's a tough one. Don't hang up your board just yet, though – forecasts can change, and it tends not to stay this poor for long.
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.
