The Lowdown
Alright, Rusty here. Let’s have a look at the charts for our local stretch.
Well, I’ll be honest with you—this is a tough run. The finder is quiet, and for the next couple of weeks, Mablethorpe is looking pretty flat. We’ve got a long gap of nothing special on the horizon. The first few days, from the 9th right through to the 16th, it’s all small stuff. Tiny waves, mostly under 2ft, with weak energy (4 to 37 on the energy scale). The wind is all over the place, but the swell just isn’t there. Honestly, it’s a kite surfer’s window more than a paddle surfer’s—strong cross-shore breezes and tiny waves don’t add up to a good surf session.
The water on the 9th is a real standout, though—65°F, which is a massive 6°F warmer than normal for this time of year. That’s very unusual, so if you’re going for a swim, it’ll feel like a tropical treat.
Things start to perk up a little on Monday the 21st. Monday morning we see a modest pulse of 3ft from the north, with moderate cross-offshore winds from the WSW at 22 mph. The energy is moderate (72). Then Monday afternoon, the best of the whole forecast arrives: 4ft from the NNW, with a period of 8 seconds, and a fresh offshore wind from the west at 22 mph. The combined energy jumps to 185—moderate, but the biggest we’ll see. This is the standout. The wind will keep it clean, and the size is just right for a fun session. It’s not a monster, but it’s the only real wave in the whole 16 days.
After that, Tuesday the 22nd drops back to 2ft, and then it’s back to tiny dribble for the rest of the week.
So, the call is simple: if you’re desperate, keep an eye on Monday the 21st afternoon. Otherwise, it’s a long wait. The blank run is pretty normal for this area when the pressure sits wrong.
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.
