The Lowdown
Hey, Rusty here. I’ll level with you – Mablethorpe’s forecast is a tough one to write. We’re looking at a long, dry spell to kick things off. For nearly two weeks, it’s tiny, weak, and not worth paddling out. Swell heights are stuck around 0.7 ft to 2 ft for days, with the combined wave energy barely getting out of single digits for a solid stretch. That’s flat, lifeless stuff.
The water is a balmy 68°, which is 7° warmer than normal for this time of year. That’s a massive anomaly – feels like you’re in a different ocean, but it’s about the only exciting thing.
The first real chance of a wave comes on Saturday 30 August. The morning brings a 5 ft swell from the ENE, with a 7-second period and combined energy of 166 – finally some proper push. The wind is a clean, moderate offshore from the WSW, which will leave the surface glassy. That’s your best window. Mablethorpe is an inconsistent, beginner-friendly beach break, and while the ENE swell isn’t its ideal direction, those clean offshore conditions will make it surfable. The afternoon slides back off a bit.
Earlier, around 24-25 August, we see a spike in size (5 ft – 6 ft) from the north with energy in the 200-400 range, but the wind is a messy cross-shore, and the conditions are tagged as “poor.” That’s more of a kite session than a surf.
So here’s the plan: wait it out. The best call is the morning of Saturday 30 August. It’s not perfect, but it’s clean and it’s the only real option on the board. Things can change, so don’t give up hope completely.
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.
