The Lowdown
Alright folks, Rusty here. Let’s be straight with you—this Mablethorpe rundown is a tough one to write. I’ve scanned every single day from now through the 25th of August, and I gotta be honest: there’s no real surf to get excited about. Not a single day ticks enough boxes to make it worth dragging your board out. The waves are small, the energy is weak, and the conditions just aren’t coming together. We’re looking at a solid 16-day gap of pretty much nothing.
The water temp is running about 67°F around the 10th, which is much warmer than normal for this time of year, but that’s small comfort when you’re staring at flat lines.
The only spot we’ve got in the mix is Mablethorpe. It’s an inconsistent, beginner-friendly sandbar that’s fairly exposed to the north, but it rarely offers anything worth paddling for. The best we see is a few pulses of waist-high swell, but they’re generally short-period junk. The combined swell energy barely cracks double digits most days, hitting a high of just 75 on the 11th afternoon, which is still weak.
The only moments that might raise an eyebrow are the 17th of August. Monday morning brings a clean, gentle offshore wind from the west with 2ft of swell from the north-northeast at 8 seconds. Combined energy is a modest 53. Then Monday afternoon goes glassy, with a calm wind and 2ft of north swell at 9 seconds. It’s small, but it’s clean. If you’re desperate for a float and a few knee-high rollers, that’s your window. Don’t expect any power or push.
Later on, the 24th and 25th of August show a little uptick—3ft to 3ft from the north-northeast, but the period is still short (6-7 seconds), and the combined energy is only around 45-49. The winds turn clean offshore from the west-northwest and west, so the surface will be smooth. But again, it’s not surf that’s going to get your heart rate up.
Bottom line: if you’re a beginner who just wants to sit on a board in the warm water, the glassy spell on the 17th afternoon is your best bet. For anyone else, this is a long dry spell. Sometimes these flat runs happen, and it’s just the way it goes. Forecasts can change, but right now, don’t plan your trip around it.
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.
