The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough one. The entire 16-day window for Mablethorpe is a write-off for quality surf. The swell is just too small, the periods are short, and the winds are rarely on our side. There’s not a single session that’s worth paddling out for.
Let’s look at the numbers. The best swell we see comes on the 31st of July, with a tiny 3 ft swell from the north, but with a period of only 5 seconds. That’s windswell, not groundswell, so it’s gonna be weak and crumbly. The combined energy of all swells on that Friday afternoon hits a meagre 60 – that’s considered weak energy. The wind is a cross-offshore from the SSW at 22 mph, which is strong, making it clean but a battle to paddle into.
The water temperature right now is 65°F, which is a whopping 5°F warmer than normal for this time of year. That’s very unusual, but it won’t help the waves.
The rest of the forecast is a sad story. You’ve got a few mornings with clean conditions and a tiny bit of swell, like on the 27th of July with 2 ft from the north (period 8 seconds, energy 44). But it’s just not enough to do anything with. The wind shifts all over the place, from cross-on to onshore, and even when it’s offshore, the swell is flat.
Given the small, weak swell and the cross-shore or cross-onshore winds that dominate the second half of the forecast, the setup here honestly looks more interesting for kite surfing than paddle surfing. For a surfer, it’s a blank run. It’s a tough area for consistent surf, so this kind of 16-day drought is more normal for Mablethorpe. Keep your board in the car, but don’t get your hopes up.
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.
