The Lowdown

Right then, let’s have a look at the outlook for Mablethorpe.

To be straight with you, it’s a grim stretch ahead. The entire 16-day window is a write-off for any decent surf. There isn’t a single standout session in there, not one. The first recommendation doesn’t even show up because, frankly, there’s nothing to recommend. The surf is just not on.

The first few days through to about the 16th of August are a total bust with tiny waves – we’re talking 0.7ft to 2ft – and a mix of onshore and cross-onshore winds making things messy. There’s a glimpse of something glassy on the morning of the 16th with an offshore wind, but the swell is still a miserable 0.7ft with hardly any energy (8 on the scale). It’s flat, mate.

Then we get into a pattern from the 17th onwards where the swell tries to pick up a bit, but it’s still poor. The wind turns offshore a few times, like on the 18th and 19th, but the swell stays tiny and weak. The water temperature is sitting at 67°, which is much warmer than normal for this time of year – a proper anomaly – but that’s about the only interesting thing going on.

The last few days of the window, from the 25th to the 27th of August, see the swell actually bump up to 5ft to 6ft, with the combined energy getting into moderate territory (268 to 481). But here’s the kicker: it’s all coming with a strong, fresh onshore wind from the NE, making it cross-onshore and lumpy. For a beach setup like Mablethorpe, that’s not surfable for a paddle boarder – it’s more of a kite-surfing kind of scene. The period is short, around 7 to 8 seconds, so it’s just wind-affected junk.

Honestly, there’s no point highlighting any break here. It’s a blank run, and for this area, that’s pretty normal when the conditions line up like this. Keep an eye on it because things can change, but for now, leave the boards at home.

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.
