The Lowdown
Alright, I’m looking at the charts for Mablethorpe, and I gotta be straight with you – it’s looking like a flat spell. There’s nothing on the table that’s worth paddling out for over this whole 16-day run.
We kick off on Saturday, August 8th, with tiny 2ft slop from the SE at a weak 3-second period. The combined energy is only 9 (weak), and we’ve got a cross-onshore wind messing it up. That’s a no-go.
The next few days don’t get any better. Sunday the 9th through to Friday the 14th of August are all showing either non-existent swell or waves under 2ft. The energy readings are pathetic – mostly single digits. Winds are all over the place, but the swell just isn't there. You’re looking at a solid gap of about a week with absolutely nothing to ride.
The second week doesn’t save us. From the 15th of August onwards, we see a bit of a pulse on the 16th with 2ft from the NNE at 7 seconds, and energy creeping up to 46 (still weak). But it’s cross-onshore, choppy, and generally poor. The 17th has some cleaner conditions with a cross-offshore wind and 2ft swell, but again, it’s just not enough push to get excited about.
By the 19th and 20th, we’re back to tiny 0.6ft and 0.3ft waves. The water is running much warmer than normal at 68°F for that first mention, a full 7° above average for this time of year – which is very unusual, but it doesn’t help the surf.
Honestly, there is no standout here. The whole 16-day forecast is a dud for surf. If you’re really keen, the cleanest windows are those mornings with light offshore winds on the 17th and 18th of August, but the swell is just too small. For a spot that’s already inconsistent, this kind of blank run is pretty normal. Forecasts can change, but right now, I’d say save the wax.

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.
