The Lowdown
Right then, let's have a look at what's on the menu for the next couple of weeks around here. I’ll be honest with you, it’s a tough stretch. The forecast is showing a real flat spell, with hardly any energy to speak of. The only break that’s even registering is Mablethorpe, and even then, it’s a struggle.
We’re looking at a long gap of nothing until the 5th of September, so the first real chance of getting wet is Saturday morning. The swell is tiny, only 2 ft from the north, and the period is a short 7 seconds, so it’s gonna be weak and wobbly. The combined energy is a measly 26 (26). But, the wind is set to go glassy that afternoon, with a northerly breeze of just 3 mph. That’s the only time the place might look clean.
The water temperature is sitting at 66°, which is a whopping 7° warmer than normal for this time of year. That’s very unusual, so you’ll be in for a warm session, at least.
The early part of the week from the 2nd to the 4th is a write-off, with barely any swell and poor conditions. The 6th and 7th aren’t much better. The only real standout, if you can call it that, is the Saturday afternoon glass-off. It’s the best of a bad bunch. The swell is still tiny, but the conditions will be perfect. The break is inconsistent though, so don’t expect much.
Later on, the 12th of September has another glassy morning with 1 ft of north swell, but again, it’s weak. The 13th sees a pulse of 2 ft from the SSE, but it’s a short 4-second period, so it’s just wind chop.
Honestly, if you’ve got a kite, the 13th afternoon might be more interesting than a surfboard for this entire forecast. The wind is cross-off, but the swell is just too weak and messy.
Stay tuned, forecasts can change, but right now, it’s a waiting game.

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.
