The Lowdown
Alright, grab a coffee, let's have a look at what's coming up for Mablethorpe over the next couple of weeks.
It's a quiet picture. We've got a long stretch of pretty much nothing on the cards. The forecast shows very tiny waves for a solid ten days or so, with hardly any push. The combined swell energy is barely registering, sitting at just 2 to 65 (weak energy). The wind is often onshore, making it even more of a struggle. The swell direction is typically from the east and northeast, which isn't ideal. Honestly, it's looking more like a lake than the North Sea.
Wednesday 28th August morning shows a small 2ft from the northeast, but with a cross-offshore wind from the WSW, it could be clean. The period is a washout at 6 seconds, and the energy is only 28. Not exactly something to call in sick for, but it's clean. The afternoon gets a similar 1ft from the NE, now with a proper offshore wind from the west, making it look clean and smooth. It's tiny though.
The following Saturday and Sunday (31st August and 1st September) see a little bump from the north. Swell heights of 0.3ft to 1.0ft, with periods around 7-8 seconds. The winds are offshore (WNW, WSW) or cross-offshore, so it'll be glassy and clean. Energy is still very low, like 1 to 12. It's basically a flat spell with a clean surface. Maybe something for a longboard or a learner to get wet, but not real surf.
There is one glimmer of hope further out. Tuesday 8th September afternoon shows a spike in energy to 141 (moderate energy), with a 3ft swell from the north, a 10-second period, and a strong offshore wind from the west. That's the best-looking day in the whole run. The water temperature is about average for this time of year.
The rest of early September is a washout, with very small waves and often cross-onshore or strong winds. The 10th September is back to tiny 0.7ft slop.
So, the honest truth: there's no true standout on offer here. The whole 16-day window is a flat run for Mablethorpe. The one to keep an eye on is Tuesday afternoon, the 8th of September. It has the most energy, a decent period, and clean offshore winds. For everything else, it's a long gap of flat conditions. For a beach setup like this, with no swell and strong onshore winds, it's probably better for a kite than a paddle if you're desperate. But forecasts can change, so don't bin your board just yet.

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.
