The Lowdown
Right then, let's have a look at what's on offer for Mablethorpe.
Honestly, it's a tough one, mate. The entire 16-day window is looking pretty grim. There's not a single session that I'd even bother paddling out for, so I'd say it's a straight-up blank run. The surf is just poor across the board, with combined swell energy barely getting out of the single digits most days, only occasionally scraping into the 40s or 50s. It's not unusual for this area to have a quiet spell, but this one's a proper flat spell.
For the first week, there's nothing. From Tuesday, the 4th of August onwards, we're looking at a mix of tiny, short-period windswell and mostly onshore or cross-shore winds. The best of a bad bunch is probably early on the 7th of August, with a light offshore breeze, but the swell is only 2ft from the north with a 8-second period, and the combined energy is a weak 66. It's clean, but it's knee-high mush. The water temperature is a very unusual 68°F, which is 7°F warmer than normal for this time of year, so you'll be warm, but that's about the only positive.
The second week doesn't get any better. We see a few more days with offshore winds, like the 13th of August, where it's clean with 2ft of swell, but the energy is still rubbish. The only slight bump in the whole period is on the 19th of August, where the swell pushes to 4ft from the north with a 6-second period. The combined energy hits 105, which is at least moderate, but the wind is either cross-shore or onshore, so it's going to be a messy, choppy mess. That's not good for a paddle surfer. Honestly, with that kind of chop and weak swell, the setup might be more interesting for kite surfing than anything else.
Don't get your hopes up for this one. Sometimes the forecasts change, but for now, it's a full-on flat spell.

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.
