The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the Mablethorpe stretch over the next couple of weeks.
Straight up, it's a flat spell and a half. We're looking at a long gap of tiny, unrideable surf from now until the middle of the month. For days on end, the wave heights are barely a whisper, mostly under 2ft, with the combined energy barely registering, so don't even bother checking the boards. The wind is offshore a lot of the time, which is a tease, but with no swell to work with, it's just a clean, flat ocean.
We finally get a flicker of life on the afternoon of Wednesday the 16th of September. The swell bumps up to 3ft from the north, with a period of 8 seconds and the energy hitting 115. It's still classed as poor surf, but it's the biggest it's been in a fortnight. The wind is light and cross-shore, so it won't be a total mess, but it's not a standout.
The real story, the only one worth circling on the calendar, arrives on Monday the 21st of September. For the morning session, we see a jump in swell to 6ft from the north-northeast, with a period of 8 seconds and a combined energy reading of 419. That's the most significant push of the whole forecast. The wind is a cross-off from the west-northwest at 19 mph, which should keep things reasonably clean. But listen, this is the only real pulse of size in the whole window, and by the 21st it's a long way off, so keep an eye on it but don't bank on it.
Bottom line: there's a whole lot of nothing, then one promising-looking day way out near the end of the forecast period.

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.
