The Lowdown
Alright folks, Rusty here. Look, I’ve scanned the charts for the next couple of weeks, and I gotta be straight with you – it’s looking pretty grim. We’ve got a big, long gap of nothing special to start with, and honestly, the whole 16-day window is a write-off for any decent surf. There’s nothing on offer that’s worth getting excited about.
The first chance for a paddle comes on Monday, the 31st of August. Mablethorpe is showing a tiny 1ft north swell, with a short period of 7 seconds. The combined energy is a weak 8, so it’s barely a ripple. Winds are offshore from the WNW, which is nice and clean, but there’s just no grunt to the waves. The water temperature is about average for this time of year, nothing to write home about. This is strictly beginner territory, and even then, it’s inconsistent.
We roll into Tuesday, the 1st of September, and it’s more of the same. The swell bumps up to 2ft from the north, but the period drops to a paltry 6 seconds, making for a weak, jumbled mess. The combined energy is only 18. The wind stays clean out of the WSW, but the surf quality is poor. It’s a session for the foam boards only.
The rest of the first week is a total dud. From Wednesday the 2nd right through to Sunday the 7th, we’re looking at tiny waves, mostly under 2ft, with short periods and poor surf conditions. The energy values are all in the low double digits, with some days dropping to a pathetic 2 or 3. The winds are mixed, but it doesn’t matter because there’s no swell to push around. You’ll be spending more time sitting on your board than riding waves.
Heading into the second week, things get a little weird. On Monday the 7th, we see a shift in the swell direction to the southeast, with a period of just 4 seconds. The swell height hits 4ft in the afternoon, with a combined energy of 65. That’s the biggest reading we get, but with that ultra-short period, it’s going to be a bumpy, sectiony mess. The wind is light cross-offshore, so it’ll be clean, but the wave quality will be poor. This is not a surfer’s swell.
The outlook doesn’t improve. The rest of the second week has the same story: small, weak swells, poor quality, and nothing to recommend. There’s a brief moment on Saturday the 12th where we get a 1ft north swell with a decent 11-second period, giving a combined energy of 33. The morning wind is light offshore from the west, so it could be glassy. But the swell is just too small to do anything with. This is a classic blank run for the area, and it’s not unusual to see such a long stretch of nothing.
Honestly, if you’re looking for a wave, leave the surfboard at home. The setup at Mablethorpe is a beach break, and with the strong winds and poor, short-period swells we’re seeing, it’s looking far more interesting for kite surfing than paddle surfing. The forecasts can always change, but as it stands, there’s just nothing to chase.
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.
