The Lowdown
Alright folks, Rusty here. Let’s have a look at what the next couple of weeks are serving up for Mablethorpe.
To be honest, it’s a pretty grim stretch. This is a real flat spell coming our way, and you’ll be waiting a long time for anything rideable. The first real chance to even get a wetsuit on isn’t until the morning of Sunday, August 23rd, and even then it’s just a tiny, gutless ripple. Between that Sunday and the following Monday, September 2nd, there are massive gaps of days with absolutely nothing worth paddling for.
The water is a real talking point though. Right now we’re looking at a water temp of 68° – that’s a massive 8° warmer than average for this time of year. Very unusual for the UK, and it’ll be a pleasant surprise if you do get in.
Mablethorpe, the only break on the cards, is a beginner spot that’s inconsistent and only fairly exposed to the north. The swell is tiny and weak, and the direction is largely from the north or north-northeast, which is what it needs. But the energy is a joke. The best of the very worst is the morning of Sunday, August 23rd. We’ve got a glassy, clean surface with a light southeasterly wind, but the swell is a pathetic 3 ft from the north-northeast with a short period of 8 seconds. The combined energy is a measly 87, which is barely a ripple. It’s surfable, but only just.
The next tiny flicker of hope doesn’t appear until the afternoon of Monday, August 31st. A 4 ft north swell with a period of 8 seconds pushes the combined energy up to 256. That’s a moderate pulse, but it’s getting hammered by a 25 mph west wind offshore. That’s a strong offshore, which will rake the surface clean, but it’s going to be a real battle to even get out there. Hard to paddle into, and honestly, it’s still a poor setup.
The most promising of an awful lot comes on the morning of Wednesday, September 3rd. A 4 ft north swell, 8-second period, and a moderate 12 mph west offshore wind. The combined energy hits 247. It’s clean, but it’s still just a small, ordinary wave. The breaks are spread out, and the quality is not there. This is about as good as it gets, and it’s not saying much.
Look, there’s no standout here. This is a period of very poor, underpowered surf. The only real highlight is the clean, glassy conditions on the morning of the 23rd, but it’s so small. If you’re desperate for a paddle, that’s your window. Otherwise, the forecasts can change, so keep an eye on it, but right now, I’d save the petrol.
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.
Mablethorpe is 20 km (12 miles) from Skegness. If you plan a holiday in Lincolnshire, look for hotels and other accommodation in Skegness. Skegness has rooms for a wide range of budgets as well as car hire and transport links.
