The Lowdown

Alright, Rusty here. Let's be straight with you about Mablethorpe. I've had a good look at the charts and, honestly, there's nothing to get excited about. The whole 16-day window is pretty much a write-off for any kind of decent surf. We're looking at a long, flat stretch with only tiny dribbles of energy.

The first bit of action, or what passes for it, creeps in on the morning of Tuesday the 15th of September. The swell is a measly 0.7 ft from the north, with a period of 12 seconds. The combined swell energy is a weak (11), so you're basically looking at lake-like conditions. Offshore wind from the west at 19 mph will keep the surface clean, but there's just no power to push the waves. It's a beginner-friendly height, but with the inconsistency and the overall lack of push, even a beginner would be frustrated. The water temp is about average for this time of year.

We trundle on through the rest of the week and into the next. The Wednesday afternoon of the 16th sees a tiny bump to 2 ft, but that's with a short period of 7 seconds and a cross-onshore breeze, so it'll be a messy crumble. Thursday the 17th manages 2 ft from the north, again not great. There's a slight improvement on Friday the 18th with a west-southwest offshore wind keeping things tidy on the 1 ft, but it's just not enough. The swell energy barely reaches double digits most of the time.

Now, we hit a real dead zone from the 20th through to the 25th. The surf is basically non-existent, with heights bouncing between 0.3 ft and 0.7 ft. It's incredibly weak. There's a stretch there with glassy conditions on the afternoon of Monday the 21st, which would be beautiful if there was any swell to ride, but there isn't.

Towards the very end of the forecast, around the 27th of September, we see the biggest numbers of the whole run. The morning brings 2 ft from the east-southeast. The period is a short 5 seconds, so it's windswell, and the wind is onshore or cross-onshore, chopping it up. The combined energy jumps to (46) and (49), which just shows how small everything else was. But the onshore wind and short period mean it'll be a bumpy, low-quality mess. Not worth a paddle.

So there you have it. Nothing stands out. The whole period is a flat spell, and with the break being inconsistent at the best of times, a blank run like this is pretty normal. Don't bother waxing up your board yet. Forecasts can change, but right now, it’s looking like a good time to clean the wetsuit.

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.
