The Lowdown

Alright, Rusty here. Let’s be straight with you – this outlook for Mablethorpe is a tough one. Right across this 16-day window, there’s just no surf worth paddling out for. We’re looking at tiny waves and a whole lot of frustration. The swell energy is weak, mostly staying between 5 and 68 in the bins, which is barely enough to roll a pebble. The water temperature is a very unusual 67°F – that’s 6°F warmer than normal for this time of year, so the sea feels like a bathtub, but there’s no juice in it.

Tuesday the 11th of August kicks off with a 2ft north-northwest swell at 8 seconds, but it’s all cross-onshore wind and choppy. Combined energy is a feeble 51. Wednesday the 12th drops to 1ft and 3ft, but the period is a terrible 5 seconds and the wind is onshore again. Thursday the 13th is even worse – a 1ft to 3ft east-southeast windswell at 4 seconds, meaning absolute closeouts and no shape.

Friday the 14th and Saturday the 15th offer a clean morning with some light offshore or cross-offshore wind on a 0.7ft to 1ft north swell, but there’s simply no wave height to work with. Sunday the 16th morning is glassy – a rare moment of flat calm – but again, the swell is a pathetic 0.7ft at 9 seconds. It’s clean but you’d be floating.

From Monday the 17th onward, we see a long gap of nothingness. The swell barely creeps above 2ft, and when it does, like on the 23rd of August with a 3ft east-southeast swell at 5 seconds, the wind is clean but the period is too short for any real push. By the 24th and 25th, the wind turns into a strong breeze (28 mph offshore), making it clean but impossible to paddle into the tiny slop.

There’s no standout session here, not one. The best you could hope for is a float on a glassy morning around the 16th of August, but that’s more of a swim than a surf. If you’re into kite surfing, there’s plenty of wind later on, but for a paddle surfer, this is a blank run. It happens in this area – sometimes the forecast changes, but right now, it’s a full 16-day hole.

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.
