The Lowdown
Alright, Rusty here. Let’s have a look at what we’ve got coming up.
Honestly, it’s a pretty lean run for the next couple of weeks. The first proper wave worth talking about doesn’t show until Saturday the 22nd, and even then it’s nothing to write home about. For the most part, we’re looking at a lot of small, weak swell with poor conditions. There’s a huge stretch from now all the way through to Saturday morning with nothing surfable, so don’t bother checking the cams until then.
The only two days that even flicker to life are Saturday the 22nd and then Wednesday the 2nd of September. Saturday morning at Mablethorpe has some 3ft of north swell (9-second period) and clean conditions with a light cross-offshore breeze. It’s surfable, but just barely. The wave energy is moderate (151), but the shape will be ordinary. It’s a beach break with north swell, and this setup will be a bit walled-off and tricky.
The better of the two and the real standout comes on Wednesday the 2nd of September in the morning. Swell bumps up slightly to 3ft from the north, with a moderate offshore wind out of the west, making for clean faces. The period hits 9 seconds, so it’s got a touch more push, and the combined energy is 139. It’s still small, but it’s the cleanest wave in the whole window. That morning is your best bet if you’re desperate for a paddle.
Water temp is sitting at 69°, which is a massive 8° above normal, so it’s much warmer than usual for this time of year.
Overall, the consistency is poor. This area is prone to flat spells like this, so don’t be surprised. Forecasts can change, but right now you’re waiting until the first week of September for the best of a pretty average bunch.
Stay patient.

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.
