The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for the Mablethorpe stretch.
To be straight with you, this is a quiet run. For the next sixteen days, the swell is mostly small and weak. There’s a long gap of poor to non-existent surf until we get a slight lift around Thursday the 10th of September. Before that, the waves are tiny and the energy is low. Between Tuesday the 1st and Wednesday the 9th, the combined energy barely gets into double digits most days, hanging around (12 to 65). We’re looking at ankle to knee-high stuff with northerly and north-northeasterly swells, and periods between 6 and 11 seconds. The wind does blow offshore or cross-offshore a fair bit, which would keep the surface clean, but there’s just not enough swell to work with.
Now, the one window that gets our attention is around Thursday the 10th of September. On the Thursday morning, we see a 3 ft north swell with an 8-second period and moderate offshore wind from the west-southwest. The combined energy jumps to (113), which is the most we’ll see in the whole forecast. The afternoon holds a similar 3 ft swell from the north, period stretching to 9 seconds, energy at (101), and more clean offshore wind from the west-northwest. The wave comment is "surfable waves but very ordinary conditions", so it's not going to blow your mind, but it’s the best on offer. Given the break is a beginner-level, inconsistent spot that’s fairly exposed to the north-east, the combination of a moderate northerly groundswell and clean offshore wind makes this the standout time. If you’re keen, get in the water that afternoon. The crowd is listed as "sometimes", so you might have company, but it won’t be a circus.
After that, the surf fades quickly. Friday the 11th drops back to 2 ft with energy down to (38), and then we’re into tiny, onshore junk through the weekend and into the following week. The second week looks bleak, with easterly and northeasterly wind pushing in and swells staying under 3 ft, but with short periods and poor direction. There’s nothing worth chasing out there.
The water temperature is about average for the time of year in this part of the UK, nothing unusual to report.
So, the call is simple: wait for Thursday the 10th of September. It’s not a classic, but it’s our best shot in a long, flat spell. Otherwise, the boards stay in the van.
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.
