The Lowdown
Alright, this is Rusty.
Let's be honest with you. Looking at the full 16-day window for Mablethorpe, it’s a rough one. Straight up, the models are showing a pretty grim run for surf. There’s a solid stretch of poor-quality waves, and not a single session has any real potential. The whole forecast period is basically a washout for a proper paddle. It’s one of those blanks where the setup is just not working for us.
We kick off on Monday, July 13th, with a weak little 4ft NE swell and a short, weak period of 6 seconds. The wind is a cross-on from the NNE at 25 km/h, making it choppy and lousy. The combined swell energy is a minimal 91. That’s the story for the next few days: small, weak, and onshore. The water is a warm 68° – a full 10° above normal, which is very unusual for this time of year, but it doesn't make the surf any better.
The swell tries to bump up a bit around Sunday, July 19th, with a 4ft NNE swell. The period stretches to 8 seconds, and the energy finally gets into the triple digits at 151, but it’s still just moderate. The problem? The wind is still cross or onshore, keeping it messy. By Monday, July 20th, we get a moment of glassy conditions in the morning with a WSW breeze at 5 km/h, but the swell has already dropped to a pathetic 2ft. It’s clean but flat as a pancake.
After that, it’s a long, slow fade. The swell drops to below 2ft for the rest of the run, with combined energy often in the single digits. The wind is all over the place, but it rarely works in our favor. There’s a glimmer of clean conditions on the 25th and 26th with a cross-off wind, but the swell is too small to surf. The whole period is a no-go. For a spot like this, it’s a normal part of the summer pattern. The forecasts can change, but right now, there isn't a single standout session.
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.
