The Lowdown

Mate, I’ll be straight with you – the next 16 days at Mablethorpe are a tough watch. The forecast is mostly a flat, blown-out mess, and there’s nothing here that’s gonna get the heart rate up. This is a spot that’s “inconsistent” at the best of times, and right now it’s looking like a long, blank run. The first real sign of life doesn’t show up until the very end of the month, and even then it’s pretty ordinary.

So, let’s break it down. We’ve got a solid week of nothing from Sunday the 23rd right through to Saturday the 29th. The swell is tiny, under 3ft, and the wind is mostly onshore, side-onshore, or just too strong. Sunday morning the 23rd has a glassy 3ft from the NNE, but the water is a very unusual 67° – that’s 7° warmer than normal for this time of year, which is a real head-scratcher. The combined energy is a weak 87, so it’s barely a ripple. By the afternoon, it’s gone. Monday through Saturday are all zeros – poor surf conditions, poor surf conditions… you get the picture.

The first hint of a pulse arrives on Monday the 31st of August. The morning brings a 4ft NNE swell with a short 5-second period and a clean cross-offshore wind. The combined energy is a weak 77. It’s “surfable but very ordinary.” The afternoon gets glassy with a 3ft NNE swell, energy climbs to 109 (moderate), but it’s still small and short-period. This is the best of a bad bunch. Tuesday the 1st of September is similar: 3ft from the NNE, 9-second period, clean offshore wind from the West, and moderate energy at 137. Not a stand-out, but the cleanest and most consistent the window gets.

After that, the quality drops off again. Wednesday the 2nd goes cross-offshore with a fresh breeze, and the swell stays small. Thursday the 3rd has a clean offshore 2ft NNE swell, but it’s just not enough. The last week is a mix of strong offshore winds that make it hard to paddle into, or choppy cross-onshore junk. The final days from the 5th to the 7th of September are tiny, weak, and ugly.

Look, if you’re desperate, the Monday 31st morning and Tuesday 1st September sessions are the only ones worth a look. The wind is clean, the water is warm, but it’s a beginner’s wave at best. For anyone else, it’s a skip. The setup looks more interesting for a kite surfer than a paddle surfer on most of these days. I’d wait for a different 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.
