The Lowdown
Right then, let's have a look at what's on the table for the coming weeks. I'm not gonna lie to you, it's a tough stretch ahead for Mablethorpe. We're looking at a proper flat spell to kick things off, with no real surf on offer for the rest of August and into the first few days of September. The water's sitting at 66°F which is a whopping 6°F warmer than usual for this time of year – that's really unusual, feels more like a late summer bath than the North Sea.
The first sniff of anything rideable doesn't come until the afternoon of Wednesday the 2nd of September. We get a little pulse of swell from the north, only 2ft with a period of 8 seconds. The combined energy is still pretty weak at 63, so it's not going to be any kind of classic. The wind will be light and cross-off from the NNW, which is about the best we can hope for, keeping the surface clean. It's a beginner-level wave at best.
After that little blink, it's right back into the doldrums. The 3rd of September has some 2ft north swell but with a strong 19 mph cross-off wind that'll put a bit of a chop on it. Then from the 4th through to the 7th of September, it's basically flat with a few tiny, un-rideable bumps.
There's a little more energy showing up on the morning of Monday the 8th of September. The swell height picks up to 3ft from the NNE with an 8-second period, and the combined energy hits a moderate 120. That's the biggest energy we see in the whole window. But here's the catch: the wind is onshore from the ESE at 6 mph, which will mess up any potential shape. It's a frustrating tease.
After that, it's back to tiny, poor surf and then finally dwindling out to nothing again by the 11th. Honestly, this is one of those bleak runs where you're better off checking the forecast again in a week or so. There's simply nothing worth paddling out for.

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.
