The Lowdown
Alright, Rusty here. Let's take a look at what's on the table for Mablethorpe over the next couple of weeks.
To be straight with you, the outlook is a tough one. There are no standout days, no proper swells to get excited about. The whole 16-day period is a flat, frustrating run of tiny waves and poor conditions. We’re looking at a long gap with basically nothing to recommend, and it’s not until the very end of the second week that we might see a slight glimmer of something worth paddling out for.
The first real sniff of anything comes on Thursday the 13th of August afternoon. We’ve got a brief window of glassy conditions, with a light southwest wind and the water going flat calm. The swell is a pathetic 4 ft, but it's coming from the ESE with a short period of 5 seconds, so it's windswell, not groundswell. The combined energy is still weak at 87, and the wave comment says "surfable waves but very ordinary conditions." It’s not going to be good, but it might be the only time you can get wet and not be fighting a complete washing machine. For a beginner, this is a low-risk, low-reward session.
Other than that, the rest of the time is a write-off. The water temperature is about average for the time of year, so no surprises there. The wind is mostly offshore or cross-offshore, which is a bonus, but with swell heights barely reaching 3 ft and periods often under 8 seconds, there’s just no energy to work with. The combined energy readings are almost all two-digit numbers, staying well below 100, confirming very weak wave energy. Tuesday the 19th of August morning shows a 3 ft swell from the north with a period of 8 seconds and a moderate offshore wind, but it's still poor surf conditions.
Forget about any big days. This is a period to leave the boards in the van and maybe go for a walk on the beach. It’s a blank run for the area, and it’s not unusual to see such a flat spell. Forecasts can change, but right now, there’s nothing to chase.
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.
