The Lowdown
Alright, let’s talk about this stretch of coast. I’m Rusty, and this is a tough one.
Honestly, you’re looking at a long, flat spell. From the 24th of August right through the end of the month, there’s basically nothing. Tiny, weak waves and onshore winds. You’ll be wasting your time. The afternoon of the 26th of August at Mablethorpe gives you a temporary reprieve with a glassy 0.9m swell from the ENE, but it’s short period (7 seconds) and the energy is weak (87). It’s just “ordinary” – not a session to write home about.
The first real glimmer of hope is the 6th of September. That Sunday morning, a pulse of 1.6m swell from the north rolls in, with a period of 7 seconds. The combined energy jumps to 401, which is a solid, moderate pulse. The wind is a clean cross-offshore from the NW at 20 km/h. This is your standout. For a beginner-oriented spot like Mablethorpe, this is the best you’ll see in the entire 16-day window. It’s still a short-period, windswell-type wave, so it won’t be picture-perfect, but it’s the only time the energy is there and the wind is working with us. The water temperature is about average for the time of year.
Before that, the 1st of September has some size (1.1m) and fresh offshore winds, but the energy is moderate (114) and the period is short. It’s a better session than the flat days, but it’s not a standout. The 5th of September also has a 1.0m northerly swell, but the wind swings cross-shore, creating chop.
So, the summary: a long, flat dry spell until the 6th of September. That Sunday morning is your best bet. It’s not a classic, but it’s the only real window we’ve got. After that, it drops back down to tiny, clean but weak waves. The break is Mablethorpe, a beach break that’s fairly exposed to the north. It’s known for being inconsistent, and this forecast proves it. Crowds are possible, especially on the 6th with the first decent swell in a fortnight.
Keep your eyes on the forecasts – but for now, it’s a waiting game.
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.
