The Lowdown
Alright folks, Rusty here. Let's get straight into it. The forecast for Mablethorpe is a tough one, I gotta be honest with you. We're looking at a long dry spell with hardly any surf to speak of for the next two weeks, so you'll need to pack your patience if you're hanging around this stretch of coast.
The swell energy is almost non-existent for the first twelve days, with the combined energy reading barely flickering above 10 or 20 (weak energy) most days, and often dropping to a dead zero. The water temperature is a seriously warm anomaly at 67.1°, which is a massive 6.8° warmer than usual for this time of year – that's very unusual, so you can leave the thickest wetsuit at home. But the waves? Barely a ripple. We've got a few days of light offshore or cross-offshore winds, like early on the 7th of August with a clean 2ft from the north, but that's tiny, inconsistent stuff. There's a glimmer on the 5th of August afternoon with a fresh 21 mph offshore wind, but it's only pushing 0.7ft of surf – more of a window-licking session than a paddle-out.
The real, and only, standout is looking much further ahead. On the morning of the 16th of August, the swell finally wakes up. We're looking at a solid 5.6ft of north swell, with a period of 8 seconds, and the combined energy jumps to a strong 547 (moderate to strong wave energy). That's a proper pulse. The wind is a gentle cross-shore breeze from the north-northeast at 9 mph, keeping conditions clean with just a slight cross-chop. Now, this is over a week away, so it's a promising long-range call, but it's the only real window in the whole 16-day outlook. For that one morning, it’ll be a ripper. Don't hold your breath for the rest of the fortnight.

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.
