The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this stretch of coast is looking pretty flat and sad for the next 16 days.
We’ve got a long, dry spell ahead of us. Honestly, from now until about the 11th of August, there’s absolutely nothing to get excited about. The swell is tiny, barely a ripple, and the wind is mostly rubbish. You’re looking at a solid 10-day gap of no real surf. The only break on the cards is Mablethorpe, and it’s a fickle one, breaking inconsistently. The water temperature is sitting at a balmy 67°, which is a whopping 7° warmer than usual for this time of year – that’s very unusual, almost like a warm bath.
The first tiny flicker of hope comes on Tuesday morning, 11th August. The swell finally bumps up to 3 ft from the NNE, with a period of 7 seconds. The combined energy is still weak, just 73. The morning sees a light breeze with clean conditions, and the wind is cross-offshore. The wave comment says "surfable waves but very ordinary conditions," and it scores a 1 out of 10. It’s not good, but it’s the only game in town. After that, it’s back to tiny, choppy junk for the rest of the week.
The standout? There isn’t one. If you absolutely have to get wet, that Tuesday morning on the 11th is your only real shot. The swell is small, the break is inconsistent, and it’s a beginner-level spot. Don’t expect any power or shape. For the rest of the period, it’s a write-off. Keep your board in the car and your eyes on the forecast.
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.
