The Lowdown

Right then, let’s have a look at what’s coming up for the next couple of weeks. I’ll be straight with you, it’s a bit of a slow start. For a stretch there’s really nothing worth paddling out for, so we’re looking at a long gap of quiet days right through until the second week. The good news is, the long-range picture offers a glimmer of hope if you’re patient enough.

So, Mablethorpe. That’s the only spot on the cards here. The water is sitting at 65°F at the start, which is a full 6°F warmer than normal for this time of year – that’s a very unusual and noticeable jump, feels like a warm bath.

From Wednesday the 9th onwards, we’ve got a few days with some small swell, but it’s all a bit messy. We’re looking at around 5ft on Wednesday morning from the north with a short period of 8 seconds and a combined energy of 260 – that’s moderate energy, but the wind is a cross-offshore from the NNW at 19 mph. It’s clean enough, but the wave quality is poor, and that short period means it’s not going to have any push. It fades fast. By Thursday the 10th, we’re down to 2ft, and it just gets smaller from there. Honestly, from the 9th right through to the 23rd of September, there’s a massive dead zone. Day after day of tiny, weak surf – we’re talking 0.3ft to 2ft – with periods often under 8 seconds. The combined energy drops into single and low double digits (down to 1 at times), so there’s just no power.

You’ll see a bit of a blip on Thursday the 17th afternoon. The swell bumps up to 2ft from the north, with a very long period of 12 seconds and combined energy hitting 117 (moderate). It’s surfable, but very ordinary, and the wind is a light cross-off from the SW. That long period groundswell can produce a clean wave here, but with that tiny height, you’re still fighting for scraps. It’s a tease more than a session.

The real standout, and I mean the only one worth getting excited about, is Thursday the 24th of September. That morning we see a jump to 3ft from the NNE, with an improving period of 6 seconds and combined energy up to 82. The wind is offshore from the WSW at 12 mph, making for moderate offshore and clean conditions. By the afternoon, it builds a little more to 4ft from the NNE, period 7 seconds, and the energy jumps to 111. The wind picks up to 19 mph from the SW though, turning it cross-off. It’s still clean enough, but that fresh breeze will put some texture on the surface. For Mablethorpe, that’s the best window of the whole 16 days. It’s still small and inconsistent here, which is normal for the area, so you have to take what you can get.

So, to sum it up: don’t bother for the first week and a half. Have a look at that window on the 24th. It’s not world-class, but it’s the only time the stars align for a paddle.

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.
