The Lowdown
Alright, let's get into it. I've had a look at the charts and the numbers for Mablethorpe, and honestly, there's not much to get excited about for the next couple of weeks. The whole 16-day stretch is pretty flat, with nothing that comes close to a standout session.
Let's be straight with you: the first week is a write-off. From this Friday the 11th right through to the following Sunday the 20th, the swell is tiny. We're talking 0.3ft to 2ft at best, and the combined energy is very weak at just (4) to (31) across the whole period. The water temp, when we do have it, is sitting around 64.2°, and with a temperature anomaly of +5.4°, that's much warmer than you'd normally expect for this time of year. It's a strange feeling, wetsuit weather but a warm bath on your skin.
The wind will be mostly offshore from the west or northwest on many of those days, which is usually a bonus here, but with barely a ripple to push around, it doesn't matter. You’ll see some clean, glassy conditions on the 22nd, but the swell is still just 2ft from the north with a short period of 7 seconds - not enough to do anything with.
Looking further out, the second week doesn't offer any relief. The same story: tiny, weak swell of 0.7ft to 1.3ft, often from the north, with energy readings staying very low at (1) to (29). There are some clean mornings with light cross-offshore winds, but the lack of swell is the killer. This break is described as "inconsistent", and this period proves it. For an area like this, a long blank run is just how it goes sometimes. With nothing on offer for paddle surfing, if the wind gets up those westerlies might make it interesting for the kite crew, but not for us.
That's the long and short of it, I'm afraid. No waves to chase here. Forecasts can always change, but as it stands, this is a solid "stay home and wax your board" week.

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.
