The Lowdown
Alright, let’s look at what’s cooking for Mablethorpe. I’m telling you straight up, it’s a tough watch. The whole 16-day stretch is looking flat as a pancake. Don’t get your hopes up.
Starting Saturday, 25 July, the swell is barely a bump – 0.2 ft from the north with a period around 6 seconds. The combined energy is a pitiful 3 (weak). Every single forecast says “poor surf conditions.” That’s the story for the weekend and into the week. On Monday, 27 July morning, we get a tiny pulse to 0.4 ft north swell at 5 seconds, with energy at 12 (weak). The wind is offshore from the WNW, which would make it clean, but there’s just no oomph behind it. It’s the kind of day that’s all tease and no treat.
The only highlight is Sunday, 2 August. The morning shows 0.4 ft north-west swell, period 7 seconds, with a moderate offshore breeze. But the afternoon goes glassy – dead calm, no wind at all. Swell is still tiny at 0.4 ft, but the energy gets to 16 (still weak). For a total beginner, that’s a chance to get out and feel the board under your feet, but it’s not a surfable wave. It’s a pond.
Then on Monday, 3 August, we see a slight bump to 0.8 ft from the east, period 5 seconds, energy of 38 (still weak). But the wind is cross-onshore from the NE, so it’s going to be choppy and messy. Not worth the drive.
After that, from 4 August through to 9 August, it’s all downhill. Nothing above 0.6 ft, onshore winds, and poor conditions. Energy barely gets past 30. This is a normal summer flat spell for Mablethorpe – it’s not unusual to go this long without a proper wave. Water temperature is about average for the time of year, so at least a swim won’t be a shock.
If you’re absolutely itching to get wet, the glassy session on Sunday 2 August afternoon is your only chance. It’s clean, no wind, and that 0.4 ft might be rideable on a longboard or a foil board. But for real waves? There’s nothing here. These dry spells happen, but forecasts can change. For now, leave the boards in the shed.

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.
