The Lowdown
Alright folks, Rusty here. Let’s be honest right off the bat – this Mablethorpe outlook is a tough one. We’re looking at a full 16-day window and there’s nothing here that gets the heart pumping. The combination of tiny swell and constant onshore or cross-off winds makes for a pretty grim stretch. You’ll be hard-pressed to find a wave worth paddling for.
The first few days are a total write-off. From Saturday, July 25th, right through until the end of the month, we're seeing waves barely cracking 1 foot. The wind is constantly howling from the W or WNW at 15-21 mph, which is a real shame. The water is a balmy 65°, which is a lot warmer than usual for this time of year – almost 5° above normal – but that’s where the good news ends. The combined energy is just a measly 3 to 26, which is basically nothing. It’s not surfable.
We roll into the first week of August, and it’s more of the same. Through the 1st and 2nd, the swell is still tiny, coming from the east with a short, weak period of 5 seconds. The wind is onshore, making it choppy and messy. The combined energy barely breaks 78. This is strictly a beach setup, and with that wind, you’d honestly have a better time on a kite than a surfboard.
The second week doesn’t offer any hope. From Monday, August 3rd, all the way through to Sunday, August 9th, the swell is consistently below 2 feet. The wind is mostly cross-off from the SW to W, which keeps the surface clean, but there’s just no power in the water. The combined energy values are all in the single digits or low teens. The very last day, Sunday, August 9th, has a tiny 2 foot swell from the north with a bit more energy (26) and a light W breeze, but it’s still too small to get excited about.
To be blunt, there is no standout. There is no best option. This is a 16-day flat spell for Mablethorpe. It’s a blank run. For an area like this, it’s a normal part of the cycle. The forecasts can change, but right now, you’re better off waxing your car than your board.
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.
