The Lowdown
Alright boys, let's chew the fat on this Mablethorpe forecast. It’s a tough one, I won't lie. For the next couple of weeks, we're looking at a whole lot of flat and weak surf. Only one day shows any kind of pulse, and even that’s not gonna have you calling in sick for work.
Water temp is a balmy 68°, which is about 7° warmer than it should be for this time of year. It’s weird, but we’ll take it – no need for the thick rubber.
The first two weeks are basically a write-off. From the 4th through the 17th, we're looking at tiny waves, mostly under 2ft. There are a few clean, offshore mornings, but it's just a flat, pretty ocean. You’d get more excitement watching the tide come in.
The one day that shows any sign of life is Tuesday the 18th in the afternoon (Mablethorpe). The swell bumps up to about 4ft from the north, with a period of 7 seconds. It’s not perfect, a bit lumpy and short-period, but the wind is light offshore and it’ll be clean. It’s our only real shot at a wave. It'll be surfable, just don't expect any barrels.
After that, it backs right off again, back to those weak, northerly windswells for the rest of the window.
So, there you have it. It’s a lean period. That Tuesday afternoon is the pick of a bad bunch. Keep your expectations low, and you won't be too disappointed.

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.
