The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Mablethorpe over the next couple of weeks.
Right off the bat, I gotta be straight with you: this is a tough one. The whole 16-day window is a bit of a dud for surf. There's not a single day where the waves really come together with a decent swell and good wind. Most of the time we're looking at tiny, weak waves or poor conditions. The water is a bit warmer than usual for this time of year, sitting at 66°F, but that's about the only good news.
We kick off on Monday the 20th, and it's a non-starter. The swell is a weak 3ft from the NNE with a short period of 8 seconds, and the wind is blowing cross to cross-on, making it choppy and messy. The combined energy is a measly 96. It's just poor surf, plain and simple. That theme continues all week. Tuesday is even smaller, and Wednesday afternoon sees a slight bump to 3ft, but the period is still short and the wind is cross, giving it a combined energy of 130, which is still weak. Not worth paddling out for.
We get a bit of a respite on Thursday the 23rd morning – a glassy window with no wind and tiny 2ft waves. It's clean, but there's just no power. Friday the 24th is clean with light cross-off winds, but the swell drops to a pathetic 1ft.
The weekend of the 25th and 26th is a total write-off. The swell disappears completely, down to 0.3ft or 0.7ft. We get some offshore winds on Saturday, but there's nothing to ride.
Into the second week, it's the same story. The 27th to the 30th has tiny waves, barely 0.7ft to 1ft, with occasional clean conditions but no energy. Even the most promising day, the 30th of July, has a swell of 1ft with a longer period of 7 seconds, but it's just not enough.
The final days roll into August with the same poor surf. The 3rd of August sees a bit of a cross-off breeze with a 1ft swell, and the 4th has fresh offshore winds, but the swell is gone again. There's simply nothing here to get excited about.
This is a blank run, and for this area, that's not unusual. The forecasts can always change, but as it stands, leave your board in the car and maybe go for a beach walk instead.
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.
