The Lowdown
Well, folks, it's Rusty here, and I've got to be straight with you – this stretch of coast is looking about as flat as a pancake for the next couple of weeks. Don't get your hopes up.
We're looking at Mablethorpe, and the truth is, there's nothing on the cards worth paddling out for. The whole 16-day window is a write-off for surf. The water is feeling much warmer than normal for this time of year, coming in at 67°F with a 7°F anomaly, which is pretty unusual, but it's not going to help the waves.
The first week is a total dud. From Tuesday, 25 August, right through to the end of the month, we've got tiny, weak swell from the east and northeast, with periods of only 5 to 6 seconds. The combined energy is pitiful, barely cracking 132 on the 27th morning, but that's still just surfable waves with very ordinary conditions. The wind is all over the place, mostly onshore or cross-onshore, making things choppy and messy. Even when there's a bit of glass or offshore wind, the swell is too small to do anything with – we're talking 1.0ft to 3ft at best, with energy values dropping from 132 down to as low as 2. It's a long, flat gap.
Moving into the second week, from 1 September onwards, it's more of the same. Swell heights barely reach 1ft, with periods hovering around 9 to 12 seconds, but the energy is still incredibly weak – single and low double digits. The wind is often offshore or cross-offshore, which would normally be a good sign, but with no swell to work with, it's just a tease. The wind gets strong on some days, up to 28 mph, making it clean but impossible to paddle into. A couple of spots on the 9th show 2ft swell with a period of 8-9 seconds and calm offshore winds, but the energy is still under 55, and the overall conditions are still rated as poor. Nothing here is going to get anyone excited.
In short, there's no surf to be had. The consistency is non-existent, and the breaks are rarely breaking. If you're a kite surfer, the strong, clean offshore winds might be interesting, but for a paddle surfer, this is a long, blank run. That's the way it goes sometimes. Forecasts can change, but right now, there's nothing.
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.
