The Lowdown
G'day, Rusty here. Look, I've had a good look at the charts for Mablethorpe, and I'm not gonna sugarcoat it – this is about as flat and bleak a 16-day run as you'll see. The opening stretch is a write-off, and honestly, nothing much changes. There's a solid gap of nothing worthwhile from now until the 5th of September, with barely a ripple to get excited about.
The first chance of anything rideable comes on the Saturday morning, 5th of September. Mablethorpe is inconsistent at the best of times, and the swell is tiny – only 2ft from the NNW. The combined energy is weak (72), so it's not packing any punch. The water is sitting at 66°, which is a massive 6° warmer than usual for this time of year, so that's pretty unusual. Conditions are clean with a moderate offshore breeze, so it'll be glassy, but the waves are just too small and weak to get excited about. It's a 1 out of 10 situation, really.
From there, it's back to the doldrums. The rest of the second week stays tiny, with a couple of clean offshore mornings but no swell to speak of. The only real blip on the radar is the Wednesday morning, 9th of September. The swell jumps to 5ft from the NNE, and the combined energy hits 242 (moderate), but it's a short-period 6 seconds and the wind is cross-shore, making it lumpy. The setup is a beach, so with a cross-shore breeze and a short period, it's not going to be pretty. That's really only for the die-hards willing to battle the chop.
Honestly, lads, if you're after a proper surf, you're better off waiting for the next system. The whole 16-day window is a struggle, and the forecasts are what they are. Keep an eye on it, but don't hold your breath.
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.
