The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking for the Mablethorpe stretch over the next couple of weeks.
Right off the bat, I gotta be straight with you: this outlook is a tough one. There’s a long, dry spell of nothing worth paddling out for through the end of July and into the first few days of August. The waves are tiny—mostly under 2 feet—and the energy in the water is practically non-existent, with combined swell readings barely cracking double digits. You’ll see a few mornings with clean, offshore winds, but with swell that small, it’s more of a float session than a surf. The water temp is about average for this time of year, nothing weird going on there.
The first real hint of something happening doesn’t show up until Thursday the 6th of August. Thursday morning brings a pulse of 4 feet swell from the north, with a period of 6 seconds. The combined energy jumps to 178 (moderate energy), and the wind is light and cross-offshore out of the NNW, keeping it clean. It’s surfable, but the conditions are still pretty ordinary—nothing to write home about. Friday the 7th has a similar-sized swell, around 3 feet, also from the north, but the wind swings cross-shore, which will put a bit of chop on the surface. The energy is still moderate at 142.
Saturday the 8th of August is actually the pick of the whole run. You’ve got a small but clean 2 foot north swell with a period of 9 seconds. The real story is the wind: Saturday afternoon goes glassy, dead calm, with the combined energy sitting at 59. That’s about as clean as it gets around here. It’s tiny, but if you’ve got a log and just want to trim on some clean little runners, that’s your window. Mablethorpe is an inconsistent spot, and it’s fairly exposed to the north, so when the conditions line up, you take what you can get. Crowds are possible, but with waves this small, you’ll probably have plenty of space.
After that, Sunday the 9th and Monday the 10th see onshore winds and messy, weak 2 foot to 3 foot swell. Not worth chasing.
So, to sum it up: the first week is basically flat. The standout window is Thursday the 6th through Saturday the 8th, with Saturday afternoon being the cleanest, glassy option for a small-wave cruise. It’s not a pumping swell, but it’s the best on offer.
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.
