The Lowdown

Alright folks, Rusty here. Let’s talk about what’s going on at Mablethorpe.

To be straight with you, the next 16 days are a tough watch. There’s no real quality surf on offer, and the forecast is pretty much a long stretch of small, weak waves and challenging conditions. The first real gap in the action is right from the start – you’re looking at a solid 15 days of poor surf before we get a slight glimmer of something surfable right at the very end.

The only half-decent looking window is on Wednesday, 16th September. The morning is your best bet, with a tiny 3ft groundswell from the north-northeast, pushing in with a period of 8 seconds. The combined energy is weak at 92, so it’s not got any punch, but the wind goes glassy. That offshore breeze will make it look clean, even if the waves are small and gutless. For a break that’s fairly exposed and inconsistent, a glassy morning is a treat, but don’t kid yourself – it’s not going to be a classic. The water temperature is running at 67°F, which is a massive 7°F warmer than usual for this time of year, so you’ll be comfortable in a shorty, but that’s about the only highlight.

The rest of the period is a write-off. Swells stay below 3ft, with periods mostly under 10 seconds, and the wind is often cross-off, cross, or onshore. The combined energy values are all in the low two-digit range, confirming just how weak everything is. For a beach setup like this, with small swell and poor surf quality, it honestly looks more interesting for a kite than a paddle. The afternoon of the 16th turns cross-onshore again, so don’t expect that morning window to last.

Look, it’s a blank run, and for this area, that’s not totally unusual. It tends not to stay this flat for long, but for now, the only thing worth a look is that glassy morning on the 16th. Keep your expectations low, and maybe save the wax for another week.

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.
