The Lowdown

Alright folks, Rusty here. Let’s be straight with you – this is a rough patch for the Mablethorpe stretch. The whole 16-day window looks pretty flat and lifeless, so we’re going to have to wait for any real hope. The first few days are basically a write-off, with tiny waves and poor conditions. We're looking at a long gap of nothing special until the 22nd, and even then, it's a very marginal call.

Let’s start at the beginning. Friday the 7th of August, we’ve got a tiny swell of 2 ft from the north, with a short period of 8 seconds. The combined energy is a measly 66, so there’s almost no push. The water temperature is a whopping 68°, which is about 7° warmer than normal—very unusual for this time of year. But the wind is a light cross-off, keeping the little bumps clean. Still, it’s just not enough to get excited about.

Through the rest of the first week and into the second, it’s a real struggle. Waves drop to 1 ft or 0.3 ft, with periods as short as 4-5 seconds. The energy numbers are mostly in the single digits or low teens. We get a glassy moment on Sunday the 9th afternoon, but with 0.3 ft of swell, you’d be bobbing around on a lake. The wind is messy, often cross-on or onshore, and there’s no real swell to work with.

The real standout, and I mean only one worth mentioning, is the forecast for Saturday the 22nd of August. It’s still a long way off, so consider this a promising but uncertain look. The morning shows a 3 ft swell from the north, with a period of 9 seconds. The combined energy finally creeps into triple digits at 104 (moderate energy). The wind is a moderate cross-shore breeze, which is acceptable but not perfect. The afternoon sees the swell holding at 3 ft from the north, the period stretching to 10 seconds, and the energy bumping up to 115. The wind is a similar moderate cross-shore.

For the first time in the outlook, there’s enough energy to push a few rideable waves. Because the swell is less than 5 ft, it’s fine for most skill levels. The period is just under that 11-second mark, so it’s not a long groundswell that might break too straight. If you’re desperate, this is the day to pencil in. The north swell direction is the optimum swell direction for Mablethorpe, which is a good sign. Crowds are listed as "sometimes," so you might have a few others with the same idea.

For the rest of the window, it’s a waiting game. The surf simply isn’t there. Stay tuned, and maybe the forecasts will change for the better.

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.
