The Lowdown

Alright folks, Rusty here. Let’s be straight with you. It’s looking pretty flat and grim out there for the next couple of weeks. We’ve got a long stretch of tiny, unorganized slop with not a single decent wave on the horizon. If you’re desperate for a paddle, you might find something, but honestly, it’s going to be a tough go.

The start of this period, through the 12th and 13th of August, is a write-off. We're talking ankle-biters under 2ft, mostly onshore and choppy. The energy is weak as hell too, with readings way down in the double digits. You’d be fighting more current than riding waves. Forget it.

There’s a bit of a tease on the morning of the 18th when the wind goes glassy and we see a sliver of 2ft, but it’s still poor surf conditions. The swell energy is only 33, so it’s just not there. It’s an empty ocean.

The only real pulse of swell in this whole 16-day window arrives on Sunday, the 23rd of August. The swell is still small, only 4ft to 4ft, but it’s coming from the north with a period of 6 to 7 seconds. The energy jumps to a moderate 147 on the afternoon. That’s the most we’ll see the entire time. The problem is it's accompanied by an east wind, which will make it onshore and messy at Mablethorpe. It could be a bit of a fun, sloppy closeout for the more experienced folks, but it won't be clean. The water temp is a considerable 3° above average, so that’s a bonus, but the waves just aren't worth getting too excited about. A 4ft wave of that short period is marginal, and with onshore wind, it’ll be a mess.

After that, the wind is forecast to howl from the north on the 24th, pushing 20 to 28 mph, which will just chop up anything left. The 25th and 26th settle down, but the swell disappears again. It's a blank run, plain and simple. This is one of those times where the ocean just has nothing to offer us.

Keep the board waxed and the wetsuit ready. It tends not to stay this bad for long, and a change is always just a storm away.

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.
