The Lowdown
G'day, Rusty here. ️
Well, lookin' at the charts for Mablethorpe, and I gotta be straight with ya – it's a tough stretch ahead. We've got a solid 16-day window, but the surf is pretty much flat for the entire run. There's nothin' worth paddlin' out for. The swell is tiny, often below 2 ft, and the combine energy is weak. A blank run like this is pretty normal for this part of the coast when there's no proper groundswell pushin' in.
There's a brief blip on Wednesday the 9th of September with the morning showin' 4 ft swell from the North with a period of 9 seconds and combined energy of 212 – actually looks like the most push we'll see – but the wind is a cross-off from the Northwest at 19 mph, and the "poor surf conditions" tag says it all. The afternoon eases to 3 ft, but the wind turns side-on.
After that, it's back to tiny, weak, onshore-affected slop for the rest of the period. The water temp is about 66°F which is much warmer than normal for the time of year, more than 7°F above the average – that's pretty unusual, and you might notice it if you're wettie-less, but there's no wave to ride anyway.
Honestly, there are no standouts here. Nothin' is even close to a recommendation for the whole 16 days. For the size swell we're talkin' – mostly under 2 ft – beginners wouldn't have anythin' to surf either. A few days later in the run, like Sunday the 20th, there is a small 0.7 ft swell but it's not breakin' properly at all. Hang tight and check back in; forecasts can change.
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.
