The Lowdown
Alright folks, Rusty here. Let’s be straight up about this one. We’ve got a long, flat run ahead here at Mablethorpe. The water is sitting at a very unusual 65° – that’s 6° warmer than normal for this time of year, which is a real oddity, but it doesn't do us much good with no waves to enjoy.
The entire 16-day window is basically a write-off for any proper surfing. There are no surfable recommendations at all. We’re looking at a solid two and a half weeks of tiny, weak dribble or flat calm. Right from Tuesday the 8th of September, it’s all poor surf conditions. We start with a tiny 0.3ft of north swell at about 8 seconds, carrying barely any energy (1), with a fresh offshore wind on Tuesday afternoon. It’s clean, but there's nothing to ride.
Wednesday the 9th sees a bump to 5ft from the north, and the energy climbs to moderate at (343) in the morning, but the wind is messy and cross-off, then goes cross-on in the arvo, so the quality is shot. The period is only 8-9 seconds, so it's just onshore chop. Nothing to write home about.
From Thursday the 10th onwards, it’s a depressing slide into flatness. We get little 0.7ft to 2ft slop with periods dropping to 5 or 6 seconds - that’s pure windswell with no push. The energy numbers drop into the single digits and low teens. Even though the wind is often offshore or cross-off, keeping the surface clean, there's simply no swell to work with.
The second week gets even sadder. There’s a brief flash of a glassy period on Friday the 18th afternoon, but the swell is still only 1ft. Saturday the 19th has a bit of long-period energy (12 seconds) but it’s only 1ft, so it’s just a long-waited ripple. Sunday the 20th shows the best energy of the whole period at (56), but that’s with a tiny 2ft swell and an onshore breeze ruining it in the afternoon.
Honestly, for a spot that’s already inconsistent, this is a blank run that’s pretty normal for the area when the pressure is locked in wrong. The setup here, with the combination of small swell and clean but strong offshore winds at times, actually looks more interesting for kite surfing than paddle surfing. There is simply no surf on offer. Not a single standout wave in the whole stretch. I'd give the board a rest and check back later.

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.
