The Lowdown
Alright, Rusty here. Let's look at what's on the cards for our local stretch.
To be straight with you, the next ten days or so are looking pretty flat. We're looking at a long stretch of nothing but tiny, weak waves – mostly around 1.0ft to 1ft from the north, with very weak energy (between 7 and 29 on the energy scale). The water is sitting at 67° and that's a massive 7° warmer than usual for this time of year, which is very unusual. It's going to be a tough wait.
The real standout in this 16-day window doesn't arrive until Wednesday, the 9th of September. We finally get a pulse of new swell. On the morning of the 9th, Mablethorpe gets a clean, glassy setup with a 4ft swell from the north, a period of 7 seconds, and moderate energy of 142. That glassy, light wind is a major positive, giving us clean conditions. The swell is small enough for beginners, but it's a start. The afternoon on the 9th gets a little bigger at 4ft, with energy jumping to 203, but it gets cross-on shore and choppy, so the morning window is your best bet.
After that, the swell drops back down again into poor conditions for the rest of the forecast. There's a brief moment on the 11th of September with some fresh offshore wind, but the swell is only 2ft, so it's not going to be worth the paddle.
So, if you're patient, the Wednesday morning of the 9th is the only time to get a little wet. For the rest? Leave the board in the car.
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.
