The Lowdown
Alright folks, Rusty here. Let’s have a look at what we’ve got on the cards for the next couple of weeks.
Honestly, I gotta be straight with you – this is a tough one. The entire 16-day window is looking like a flat spell for Mablethorpe. There’s simply nothing on the menu that’s worth paddling out for. We’ve got a few tiny pulses of energy, but they’re all flagged as “poor surf conditions” and the scores back that up. It’s a real bummer.
The first bit of movement we see is on Tuesday afternoon, the 28th of July, with a tiny 1 ft swell from the north. The water temperature is a very unusual 67 °F, which is a whopping 7 °F warmer than normal for this time of year – feels like a warm bath, but it won’t help the waves. The combined energy is a weak 14, so there’s just no grunt.
We roll through a few days of knee-high dribble, with the best-looking windows being the Thursday morning the 30th, with a clean 1 ft under offshore west winds, and Friday morning the 31st with a clean 1 ft. The swell period is a short 6 to 8 seconds, so it’s just windswash, not a proper wave. The energy barely cracks 15.
The weekend of the 1st and 2nd of August is even smaller. Saturday morning the 1st is glassy but only 0.7 ft, and by Saturday afternoon it’s flat as a pancake at 0.3 ft. The combined energy drops to 2 – that’s just about nothing.
There’s a slight bump of energy around the 3rd and 4th of August, with 3 ft swells showing up, but the period is a terrible 5 to 6 seconds. The combined energy gets up to 90 on Monday morning, but the wind is onshore and messy. It’s not surfable.
We get the biggest swell of the window on Thursday the 6th of August, with a 6 ft swell from the north-northeast. The combined energy jumps to 244 (moderate wave energy), but the period is only 7 seconds. With strong cross-onshore winds, it’s going to be a choppy, blown-out mess. At 6 ft, it’s already getting too big for beginners, but with that wind, it’s only really for the hardcore. Honestly, the setup looks more interesting for kite surfing than paddle surfing.
After that, it fades back into tiny, low-energy surf for the rest of the forecast. The last chance for a clean look is on Monday the 10th of August, with a 1 ft swell under offshore west-southwest winds, but it’s just too small.
So, there’s no standout, no best on offer. Just a long, flat stretch. Mablethorpe is an inconsistent spot, and this run is a perfect example of that. It tends not to stay this poor for long, but for now, leave the board at home.
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.
