The Lowdown

Alright, let's get some waves. This is your local surf reporter, Rusty.

Right, I’ve had a look at the charts for our stretch of coast, and to be honest, it’s a pretty quiet outlook. The swell energy is just not doing the business for us over the next couple of weeks. You’ll be waiting a while for any real action.

The first bit of the forecast is a tough one. We’re looking at a run of small, weak, and messy surf. Monday the 20th through to Wednesday the 23rd of July are all a write-off. We’re seeing tiny 2ft to 3ft swells from the NNE, but with periods around 6 to 8 seconds, there’s just no power. The wave energy is pathetic, barely hitting 130 (131) on the best afternoon. On top of that, the wind is mostly cross or cross-onshore, so the surface is choppy and bumpy. It’s a real struggle out there.

We do get a glimpse of some clean conditions on Thursday the 23rd morning. The wind goes glassy, dead calm, and the water is likely to be clean. But the problem is the swell is still tiny, just 2ft from the NNE with a combined energy of only 47. It’s a nice morning for a paddle, but not for a proper surf.

The best chance for a clean wave comes on Friday the 24th and Saturday the 25th of July. The wind swings offshore from the west-northwest, giving us clean, smooth faces. The swell is still small, though, dropping from 2ft to just 1ft. The wave energy is very low (20 down to 11). It’s a good opportunity for a beginner or a longboarder to get a few little crumbly waves, but if you’re looking for a proper barrel, you’ll be disappointed.

After that, things get even smaller. From Sunday the 26th of July right through to the end of the forecast on Tuesday the 4th of August, the swell is almost non-existent, with heights mostly below 2ft and energy levels in the single digits. The wind is occasionally offshore, which keeps it clean, but there’s just no wave to ride.

The standout, if you can call it that, is the morning of Friday the 24th of July. The offshore wind from the west-northwest at 15 km/h will have Mablethorpe looking clean. The swell is a tiny 2ft from the north, with a period of 6 seconds. It’s not a day to get excited about, but it’s the only window where the conditions are clean and the swell is just about big enough for a soft-top. The water temp is about average for the time of year, so no surprises there.

Don’t hold your breath for the second week. It’s essentially a flat spell. A few clean mornings with offshore wind, but no swell to speak of. The forecast can change, but right now, it looks like a good time to check the wax on your board and wait for a better window.

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.
