The Lowdown
Alright, listen up. Rusty here. I’ve been staring at the charts for Mablethorpe and, well, it’s a bit of a tough stretch for us paddle surfers. I’ll be straight with you – the next couple of weeks are looking pretty flat and messy for the most part. There are no good surf options in this 16-day window, so don’t go getting your hopes up for any hero waves.
The water is running about 67°, which is much warmer than normal for this time of year – that’s a bit of a bonus if you do get out there for a splash around.
We’ve got a long gap of nothing but poor conditions stretching from now through the end of the period. The swell energy is weak, with values mostly in the single digits and teens – that’s barely a ripple. The wind is all over the place, mostly onshore or cross-onshore, which will chop up anything that tries to show.
There’s a tiny blip around the 16th and 17th where the energy picks up to a moderate 103, and we see a NE swell of about 4ft, but the period is short and the wind is howling cross-shore. It’s going to be a lumpy, messy close-out. Not worth the paddle out unless you’re just keen for a fight. For the beginners, that 4ft is manageable, but the conditions will be rough.
Honestly, the surf quality is poor across the board. The swell direction is mostly from the N or NNE, which doesn’t match the optimum N direction for the spot, and the periods are often short, under 8 seconds, which means weak, unorganized waves.
The only times the water looks clean are when it’s flat, like on the morning of the 14th and the morning of the 24th, but with 1ft and 0.3ft of swell, there’s nothing to ride. It looks more like a good time for a beach stroll than a surf session. If the wind stays up and the swell gets a bit of shape, it might be more interesting for the kite crew than for us.
So, keep the board in the van and the wax in the wrapper. This is one of those blank runs that this area can throw at you. It won’t stay poor for long, and the forecasts can change, so I’ll keep an eye on it. But for now, there’s nothing to get excited about.
Rusty out.

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.
