The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.

Honestly, I've got to be straight with you – it’s looking like a lean run for a while. There are some good waves to be had, but you’ll have to be patient and pick your moment. The first week or so is pretty flat, but we’ve got a glimmer of hope later on.

For the first several days, from Wednesday the 12th through to the end of the following week, it’s just not happening. The swell is tiny, mostly under 3 ft, and when it does show up, the wind is often messy. There’s a lot of cross-onshore chop and short-period, weak energy (combined energy stuck between 11 and 43). It’s just not worth getting wet. You’d be better off checking the tide pools.

Then, things start to shift. Thursday the 20th of August sees a pulse of northerly swell arrive, but it’s a messy cross-shore wind and a beachbreak setup. That’s kite-surfing territory, not paddle surfing. The waves are 5 ft but the quality is poor.

The real standout in this whole forecast, the one that has my heart beating a little faster, is the morning of Tuesday the 25th of August. At Mablethorpe, we’ve got a solid northerly swell pushing in at 2 ft. The period is 9 seconds, which is decent, and it’s coming from the north – the optimum direction. The combined energy is a moderate 76, so there’s a bit of push behind it. The key here is the offshore wind from the WNW. It’s light, clean, and will carve those waves up beautifully. The report says "surfable waves but very ordinary conditions" but a score of 1/10 feels like a harsh rating for a clean, offshore morning with a pulse of swell. This is *the* session to aim for. Keep in mind it’s a beach break, so it’ll be a bit of a free-for-all, but with the right wind, it’ll be a fun one.

Later on, the morning of Thursday the 27th of August also has potential. There’s a north-northeast swell at 2 ft with a 9-second period, and the combined energy jumps to a more substantial 228. The wind is WSW cross-off, which is clean. It’s a long way out, so don’t get your hopes up too much, but it’s one to keep an eye on.

So, in short: there’s a big gap with no surf, then a few days of messy, big windswell, then a clean, offshore morning on the 25th that looks like the pick of the bunch. Be patient, and you’ll be rewarded.

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.
