The Lowdown
Alright lads, Rusty here. Let’s break it down for Mablethorpe. Over the next 16 days, it’s a lean spell. The first surfable day doesn’t roll around until Friday the 7th of August, so you’ve got a few days of nothing right at the start.
The water is running at 67°, which is a whopping 7° warmer than normal for this time of year. That’s very unusual, so you’ll be feeling that warmth.
The one real highlight in the whole stretch is Sunday the 16th of August, specifically the afternoon. We’re looking at a clean 4ft north swell, with a gentle offshore breeze from the west. The combined energy is moderate at 119. It’s a short-period windswell, but it’ll be clean and rideable. This break is inconsistent and best for beginners, so don’t expect perfection. Crowds can pop up sometimes, but it’s not a circus.
Before that, Friday the 7th of August morning has a tiny 2ft north swell (69 weak energy) with a light offshore, keeping it clean. And Tuesday the 11th of August sees a 2-3ft north-northeast swell with moderate energy (130 morning, 111 afternoon), but the wind is onshore, so it’ll be messy – more of a kite day than a surf day.
The rest of the run is tiny, with mostly offshore winds but barely any wave height. The morning of Tuesday the 18th of August is glassy with a 2ft north swell, but the energy is weak (17) and the period is short (5 seconds). It’s clean but barely a ripple.
If you want the best chance, aim for the afternoon of Sunday the 16th of August. Otherwise, it’s a quiet stretch. That’s just how it goes here sometimes. Forecasts can change, so keep an eye out.
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.
