The Lowdown
Alright, Rusty here. Let’s talk about what’s on the table for Mablethorpe over the next couple of weeks.
Look, I hate to be the bearer of bad news, but we’re staring down a long, frustrating dry spell. For the next week and a half, there’s barely a whisper of proper surf. Most days are looking at tiny, weak windswell with crummy onshore winds, and when the wind does swing offshore, the swell just completely shuts off. It’s the kind of setup that makes you want to leave the boards in the garage.
The water temp is about where you’d expect for this time of year, nothing wild.
We don’t really get a genuine look at decent waves until well into the second week. The first real sniff of something interesting shows up on Wednesday, the 2nd of September. There’s a late-arriving pulse of northerly swell that bumps up to around 7.2ft. The energy is strong – we’re talking a combined energy reading of 1075 – but the winds are howling from the WSW at 22 mph, making it a cross-offshore breeze. It’s clean, but that’s a lot of power with wind on it. At that size, it’s starting to get a bit much for a learner.
After that, it drops back down into the small stuff, with nothing else really screaming "paddle out."
So really, if you’re desperate for a wave, the only true stand-out in the whole 16-day window is that Wednesday, 2nd of September window. It’s a long way out, so treat it as a promising possibility rather than a guarantee. It’s a beach break, so that long-period (11 seconds) northerly swell might be a little straight, but it’ll have some punch. If you’re an experienced surfer who can handle a bit of wind and size, mark that date. Everyone else, just wait.

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.
