The Lowdown
G’day, Rusty here. Let me tell you, it’s a bleak picture for a while. The water temperature at Mablethorpe is sitting at a very unusual 67°F, which is much warmer than normal for this time of year, like the ocean’s taken a holiday.
From the 10th all the way through to the 23rd of August, it’s a dead zone. There are a few little bumps here and there, but with onshore winds and low energy, there’s nothing to chase. On the 12th and 13th, you get some small swells – around 1ft to 2ft in the afternoon – but the wind is cross-onshore and the conditions are choppy. Not worth the drive.
Then on Sunday the 23rd of August, the afternoon brings a pulse of 6ft swell from the north with a period of 8 seconds and a combined energy of 319 – that’s moderate but the wind is onshore and the conditions are unknown, more than likely messy. That’s too big for beginners, but it’s not clean enough for anyone else either.
The one session that stands out is the following morning, Monday the 24th of August. That morning we get a clean 4ft swell from the north-northeast with a period of 7 seconds and a combined energy of 151. The wind turns offshore from the west-northwest at just 6 mph, which will keep the surface glassy. It’s only rated as surfable but ordinary, but after two weeks of nothing, that’s the best we’ve got. The swell direction isn’t ideal – Mablethorpe likes it straight from the north – but with clean conditions, you’ll still find a few fun ones. The short period means the waves will be a bit soft and sectiony. That afternoon gets blown out again by onshore easterlies.
Tuesday the 25th of August morning goes glassy again, but the swell drops to just 2ft – not enough to hold you up. The rest of the outlook flattens right out.
Bottom line: your only real shot is Monday the 24th of August morning. It’s not firing, but it’s clean and ridable. Everything else is a no-go. Don’t lose hope though, the surf always comes back around.
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.
