Mablethorpe Surf Forecast and Surf Report

G'day, Rusty here. Let me tell you, looking over the next 16 days for Mablethorpe, it’s a grim picture. We’ve got a long, barren stretch ahead. Honestly, there’s nothing that I’d call a proper surf session in this whole forecast window. It’s a tough run, and for this area, that's the reality of it.

The first glimmer of anything surfable doesn’t pop up until Sunday the 23rd of August, and even then, it’s a stretch. We’ve got a solid week of flat, weak, and often onshore junk before that. The water is currently sitting about 69°, which is much warmer than normal for this time of year – weird, but it won’t help the waves.

Alright, let’s walk through it. Thursday the 20th and Friday the 21st of August offer nothing. Tiny swell, poor conditions, and a storm risk early on. The combined energy is pitiful, sitting at 18 on Thursday morning. Saturday the 22nd keeps the poor form going with messy cross-shore winds.

Sunday the 23rd of August morning is your best bet, which is really saying something. We’ve got clean, offshore wind from the west at 6 mph. The swell is a tiny 0.7 ft from the NNE with a period of 8 seconds. The combined energy is a weak 70, and the wave comment says "surfable waves but very ordinary conditions". It’s a gentle offshore and clean, so for a beginner on a longboard, you might catch a few knee-high lumps if you’re desperate.

From Sunday afternoon all the way through to Friday the 4th of September, it’s a total write-off. The wind is either onshore or cross-shore, the swell heights barely tickle 4 ft at best on the 25th, but that’s with a nasty onshore wind and a short, weak period of 6 seconds. The energy in that one hits 129 on Tuesday morning the 25th, but with onshore wind and a period that short, it’s just ugly, blown-out chop. Not for paddling.

We get a few more clean, offshore wind windows on the morning of the 28th and 29th of August, and again on the 4th of September, but the swell is practically non-existent. On the 4th of September morning, we’re down to 0.3 ft and a combined energy of just 1. It’s flat.

So, to sum it up: there’s no standout. No hidden gem. The only window where you could even get wet is Sunday the 23rd of August morning, and that’s only if you have zero expectations. It’s a long, quiet period ahead. Stay patient, keep an eye on the charts, because it tends not to stay this poor forever. Forecasts can change.

Rusty.
