The Lowdown
Alright, Rusty here, and I gotta be straight with you. The next 16 days at Mablethorpe are a total write-off. The finder didn't flag a single good session, not one. For this area, that’s a bit unusual, but it happens. The good news is it never stays this dead for long.
The water is cooking at 68°, which is a whopping 7° warmer than usual for this time of year. That’s very unusual, and about the only thing that’s got any energy around here.
We’re talking tiny, gutless swell all the way to the 20th of August. The combined energy of all swells is barely a blip, mostly under 100 (9 is the highest we see early on), and the heights are rarely above 2ft. The wind switches around a lot, but even when it’s offshore, like on the Wednesday morning of the 5th with a 15 mph cross-off, or the Friday morning of the 7th with a light 6 mph cross-off, there’s just no wave to ride. The period is short, mostly under 8 seconds, so it’s weak, bumpy, and messy. Honestly, the wind is going to be more interesting than the surf for you kite surfers.
Later on, around the 17th and 18th of August, we see a little bump. Monday morning the 17th has a 3ft south-southeast swell with a fresh 22 mph offshore wind, and Tuesday morning the 18th sees a 3ft northerly with a 19 mph offshore. The wave energy even gets up to 64. But the periods are still a weak 5 to 6 seconds, so it’s not going to offer any real shape. It’s still poor surf.
So, my honest advice: leave the board at home for Mablethorpe. The forecast for the next two weeks is empty. Keep an eye on it, but for now, it’s a no-go.
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.
