The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this 16-day window for Mablethorpe is a frustrating one. We’re looking at a long stretch of small, weak surf with only a few fleeting moments that might get your heart rate up. The water is sitting at a very unusual 68°, which is much warmer than normal for this time of year, so at least you won’t freeze while you’re waiting.
The first real chance of anything rideable doesn’t show up until Friday the 7th of August. The morning will see a tiny 2ft swell from the north, with a short period of 8 seconds and weak energy (69). The wind will be a gentle offshore from the WSW, which is a major positive – it’ll keep the surface clean. It’s surfable, but it’s very ordinary. That afternoon, the wind drops to glassy, which is a treat, but the swell drops even more to 2ft. It’s a tough one to get excited about.
After that, we hit a big dead zone. From Saturday the 8th right through to Tuesday the 11th, the swell is basically non-existent, with heights between 0.3ft and 0.7ft. You’d be better off at the pub.
Things get a little more interesting on Wednesday the 12th of August. The afternoon pushes out a 3ft swell from the ESE, but it’s a short-period 5 seconds, and the wind is a moderate onshore from the ESE, making for messy conditions. The wave energy is still weak (63). It’s not great for surfing, but that onshore wind and short-period chop might make it a bit more fun for kite surfing than paddle surfing.
The rest of the run into the second week stays pretty grim. We see a few tiny pulses of 2ft to 2ft swell from the north, but the wind is often strong, with some fresh offshore breezes. The combined energy finally climbs to a moderate 117 on the 19th of August, but it’s still a weak 2ft wave. The morning of the 19th sees a moderate offshore wind, so it’ll be clean, but it’s just not enough size to get the stoke going.
The one and only real standout, if you can call it that, is Friday the 7th of August. The morning at Mablethorpe offers the best combo of the whole outlook: a clean 2ft north swell with a gentle offshore wind. It’s small, it’s inconsistent, and it’s for beginners. The crowds are sometimes a problem, so you might have some company for those tiny waves. For the rest of the 16 days, it’s basically a waiting game.
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.
