The Lowdown
G'day, Rusty here. Let's be straight with you—this outlook for the Mablethorpe area is a tough one. Over the full 16-day window, there really isn't a single standout session worth paddling out for. The water temperature is sitting at 67°, which is a solid 7° warmer than usual for this time of year—very unusual, and it'll feel like a bath.
The first spot we look at is Mablethorpe. It's a beginner-friendly beach break that's fairly exposed to the north, but it's inconsistent and can get crowded sometimes. The whole forecast period is littered with "poor surf conditions" and zero scores. From Monday 3rd August right through, the surf is tiny and weak. The combined swell energy is mostly in the low double digits, like 22 (weak) on Monday morning, and it never really gets going. The swell is coming from the east with a period of only 4 seconds—that's just wind chop, not real surf. The wind is onshore from the ENE at 12 mph, making things messy.
There's a long gap of poor or nonexistent surf. Tuesday 4th isn't any better, with small NE swell (period 6 seconds) and cross-shore winds. The combined energy is still weak, 41 in the morning. Wednesday 5th sees a brief window of offshore wind from the WSW at 22 mph, but the swell is only 1 ft from the NNE with a period of 8 seconds—barely a ripple. The energy is just 14. Thursday 6th is similar, with offshore wind but 0.7 ft swell.
Friday 7th and Saturday 8th offer some clean conditions with cross-offshore winds, but the swell remains tiny—2 ft and 1 ft respectively—with weak energy. Through the second week, from Sunday 9th August onwards, the pattern is the same: tiny swell, mostly onshore or cross-shore winds, and energy readings rarely above 30. The best you'll see is Monday 17th afternoon with 3 ft NE swell and 65 energy, but it's onshore from the ENE and the period is 5 seconds, so it's still crummy.
Honestly, this is a blank run. There's nothing here for a surfer. If you're desperate for a paddle, maybe the offshore winds on Wednesday 5th or Saturday 8th give you a clean but tiny wave, but it's not worth getting excited about. For kite surfing, the stronger cross-offshore winds on Wednesday 5th afternoon (22 mph) or Friday 14th (31 mph) might be more interesting, but for paddle surfing, save your energy.
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.
