The Lowdown
Alright, Rusty here, giving you the lowdown on Mablethorpe in feet and miles per hour.
The forecast is a tough one, mate. Over the next 16 days, there’s hardly a decent wave to be found. It’s a long, dry spell with only one brief pulse of size that’s ruined by the wind.
From Saturday, August 8th through Tuesday, August 18th, it’s all tiny, weak surf. Swell heights are under 2 feet, with short periods, and the wave energy is all weak. The wind is mostly cross or onshore, chopping everything up. There’s a clean moment on Sunday morning, August 16th, with a light offshore wind, but the swell is a pathetic 0.7 feet. Not worth wetting a wetsuit.
Then we get to Wednesday, August 19th. The swell finally shows up – 6 feet from the north, with a 9-second period. The combined energy is strong (549). But the catch is a howling 15-22 mph north wind, creating a lumpy, cross-chop. It’s big, powerful, and ugly. This is for experts only, and even they’ll be fighting it. The beach break won’t do you any favors in that mess. For kite surfers, it might be a different story, but for a paddle surfer, it’s a no-go.
The north swell continues on Thursday, August 20th, with 3 feet in the morning and 3 feet in the afternoon, but the wind is still a strong, messy cross-shore. It’s too big for beginners, but not clean enough for a good session.
The very end of the window, Sunday, August 23rd, has a 4-foot north swell, but the wind is a gentle cross-shore, and it’s still labeled “poor surf conditions.”
The only real option: If you’re an experienced surfer and you don’t mind a messy session, Wednesday morning, August 19th, is your only shot at some size with 6 feet from the north. Expect crowds at Mablethorpe and be ready for a fight with the wind. For everyone else, it’s a long wait. Forecasts can change, but right now, the cupboard is bare.
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.
