The Lowdown
Alright folks, Rusty here. Let’s break down what’s goin’ on at Mablethorpe over the next couple weeks. Gotta be straight with you—this is a brutal stretch. We’re talkin’ a long stretch of nearly flat, messy surf with barely a glimmer of hope until early August.
Sunday the 19th: cloudy with a northerly wind at 19 mph, cross-off, making a mess of the 5ft NNE swell. Combined energy is moderate (318), but the wind kills it. Poor surf. Monday the 20th drops to 3ft and weaker, with onshore wind. Tuesday the 21st is even smaller—2ft and junk. Wednesday the 22nd through Thursday the 23rd are flat and choppy. From Friday the 24th through Sunday the 27th, the wind turns offshore but the swell is tiny—0.6ft to 2ft, with almost no energy. That’s barely a ripple.
Monday the 27th morning is the first time we get something clean-ish: 2ft from the north, 7-second period, light offshore breeze, but still weak energy (32). Tuesday the 28th morning is glassy with easterly wind at just 3 mph and a tiny 1ft north swell—looks nice but unrideable. Then we get a few days of clean offshore conditions from the 29th through the 31st, but the swell is still only 1ft to 2ft, period never above 8 seconds. Not enough.
Saturday the 1st of August and Sunday the 2nd show a bit more life: a 2ft NNE swell on Sunday afternoon with a 9-second period, combined energy up to 58, clean offshore wind. It’s still small, but at least it’s clean. Monday the 3rd fades again with onshore winds.
Bottom line: Mablethorpe is an inconsistent beginner spot, and this stretch is a long, flat run. The best chance you’ve got is Sunday the 2nd of August—small and clean, with that NNE swell at 2ft and 9 seconds. Crowds can show up sometimes, but with this lack of surf, you’ll likely have the place to yourself. This is pretty normal for the area when the swell shuts off. It won’t last forever, but for now, stay dry.
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.
