The Lowdown
Alright, folks, Rusty here. Let’s check the picture for the next couple of weeks. I’ve got to be honest, it’s a real tough one. The whole outlook is flat and messy, with no real standouts, so I’ll just walk you through the few moments that might get your attention.
We’re starting with a blank slate. The first nod to any surf at Mablethorpe isn’t until Monday the 20th of July, and even then, it’s a stretch. The water is a weird 67°, which is a massive 9° warmer than it should be for this time of year – that’s a real anomaly, feels like bathwater.
For the first few days, from Friday the 17th through Sunday the 19th, it’s all poor surf conditions. The wind is a messy cross-shore, and the swell is tiny and weak, with energy levels barely hitting 12 (weak). It’s just not worth paddling out.
Now, Monday morning the 20th of July is the only thing that even comes close to a recommendation. The wind turns to a cross-offshore breeze, giving us a clean surface. We’ll see a small 4ft swell from the NNE, with a short period of 8 seconds. The combined energy is a moderate 272 (moderate wave energy). It’s a small, clean wave, and it’s a Monday morning, so the crowds might be alright. It’s a beginner spot, and for a learner, this could be a fun, clean little session. But honestly, it’s not setting the world on fire.
After that, it’s a long, bleak stretch. From Tuesday the 21st of July all the way through to Saturday the 2nd of August, the story is the same: tiny, weak swells, messy cross-shore winds, and poor surf conditions. The wave energy drops right off into the single digits (weak). There are a few glassy moments on the 24th and 25th of July, but with swells of just 2ft and 0.7ft, there’s nothing to push a surfer along. It’s a total write-off.
So, the summary is grim. We’ve got a massive gap of nothing from the 21st all the way through to the end of the forecast. The only real flicker of hope is that Monday morning session on the 20th. For a spot that’s already inconsistent, this is a proper dry spell. It’s the kind of forecast where you’d be better off looking at the tide pools or taking a long walk.
I’m Rusty, signing off.

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.
