The Lowdown

G’day, Rusty here. Let’s be straight with you—this is shaping up to be one of those quiet spells where you’re better off finding a longboard and a lake than pretending there’s real surf. The next week or so is looking pretty flat and messy, so don’t hold your breath.

We’ve got a long stretch of almost nothing on the cards. From now through the 19th, it’s mostly tiny, weak swell under about 1 foot, with a lot of poor conditions and onshore winds. You could paddle out, but you’d be doing more floating than surfing. The offshore winds on the 17th and 18th are nice, but there’s just no push behind them. Combined energy is only in the single digits and low teens (3-14), so that’s about as weak as it gets.

Things finally start to wake up a little around Thursday the 20th. The swell bumps up to a knee-high 3 feet from the north-northeast, with a period of 8 seconds. It’s surfable but nothing to write home about. The morning looks clean with light offshore winds, and that combined energy jumps to 109, so there’s at least a bit of grunt there. The issues are that this break, Mablethorpe, is inconsistent and the swell direction is straight north, which isn’t its optimum (it prefers N). It’ll be ordinary, but you could get a few grovelly ones if you’re keen.

The real standout window looks like Sunday the 23rd. The swell builds to about 4 feet from the north, with an 8-second period. The combined energy reaches 157-169, which is the strongest we’ll see all week. But here’s the catch—the wind is howling onshore from the east-northeast, making it choppy as hell. This is when I’d say the setup looks way more interesting for kite surfing than paddle surfing. For the surfer, it’s going to be a mess.

After that, it fades out again. The rest of the month sees the swell drop back below 3 feet, with onshore winds and just ordinary conditions. The 27th has a brief mention of a clean morning with offshore wind, but the swell is only 2 feet with a short period, so it’s not going to be a classic. The end of the month gets rough and flat again.

One thing to note: the water temp on the 14th is about 68°F, which is a massive 7°F warmer than average for this time of year. That’s very unusual, so you won’t need a thick suit—that’s a positive, at least.

So, bottom line: if you’re desperate, the 20th morning is your best bet for a clean, grovelly session. The 23rd has the most swell but is blown out. Everything else is a blank. It’s a poor run for a spot that’s already inconsistent, but that’s how it goes sometimes. Forecasts can change, so keep an eye on it, but I wouldn’t be rearranging your life for this one.

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.
