The Lowdown
Alright folks, let’s talk about the next couple of weeks around Mablethorpe. I’m Rusty, and I’ve been staring at this stretch of coast for a while now. Gotta be straight with you – it’s a long, dry spell coming up. For the next two weeks, this place is flat as a pancake. No surf worth paddling for. The water temp’s sitting at 20° right now, which is a whopping 5° warmer than normal for this time of year – that’s freakishly warm, so if you’re just swimming, it’s lovely, but for surf? Nada.
Then, after a solid two‑week gap, we finally get a little pulse on Saturday, 1 August. The first decent look is Saturday morning – a small 4 ft swell from the east, with a short period of just 6 seconds. That’s a weak, short‑period windswell, so the waves will be small and a bit crumbly, not much push. But the wind is light offshore from the west at 9 mph, so the surface will be clean and glassy. Combined energy is moderate at 121, so there’s enough to get a few rides if you’re a beginner or just want to bob around. The afternoon gets a fresh offshore breeze at 22 mph – that’s a bit too strong for clean surfing, even though it’s offshore, so it’ll be bumpy.
Mablethorpe is a beginner‑friendly spot, but it’s inconsistent and only breaks sometimes. The swell direction is from the east, but the optimum is north, so it’s not hitting the sandbars right. Expect it to be a bit messy, but with that offshore wind, it’ll be the best we’ve seen in ages. Crowds are possible – it’s “sometimes” busy, and with nothing else around, a few locals might pop out. Overall, it’s a very marginal day, but if you’re desperate for a paddle, Saturday morning is your only window. After that, the forecast looks bleak again. Hang tight, or find a kite – the setup on that day might actually be more fun for a kite surfer than a paddle surfer, with that fresh offshore wind and small swell.
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.
