The Lowdown
Alright, let's get real about the next couple of weeks. It's a total bummer for Mablethorpe.
The whole 16-day window is a flat and windy mess. We're looking at a solid gap of nothing from the start right through to the 9th of September. There's a pulse on the 8th of September showing a 4ft swell, but the wind is howling at 25 mph from the southwest, making it a clean but impossible paddle. The call is still poor surf conditions.
The water is a very unusual 67°F, which is much warmer than average for the time of year, but that's the only highlight.
The only time we get a hint of anything is on the afternoon of the 9th of September. We've got a tiny 3ft swell from the north-northeast with a moderate offshore wind. The combined energy is a weak 93 (moderate), but the waves will be clean and tiny. It's a "surfable waves but very ordinary conditions" kind of day. A beginner might find a little roll, but there's no power.
Then on the 13th of September, the Sunday afternoon shows a 3ft swell from the north with a 10-second period, and the combined energy jumps to 325 (moderate). The wind is cross-offshore from the west-northwest at 12 mph, keeping it clean. But the description says "marginal surf forecast or questionable tide conditions." It's going to be small, weak, and iffy.
Best of a bad bunch: If you're really keen, the 9th of September afternoon is your best shot. It's small and clean. The 13th of September has a bit more kick, but it's a long way off and the forecast is shaky. With no consistency at all, this is just a flat spell. It won't stay this way forever.

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.
