The Lowdown
Grab a coffee, because I’m going to be straight with you. It’s a tough stretch of days ahead for surf. We’re looking at a long, flat spell with very little on offer.
The water is about 68° at Lowestoft, which feels much warmer than normal for this time of year, a real treat if you do get in, but the waves just aren't cooperating.
For the next week and a half, from Tuesday the 11th through to Wednesday the 19th, it’s basically a desert out there. The swell is tiny, mostly under 3ft, and the wind is almost always onshore or cross-shore, chopping up what little bump there is. The energy in the water is weak, with values mostly under 100, sometimes as low as 2. There’s nothing to get excited about. You’re better off doing something else.
There is a brief flicker on Thursday morning the 20th. The wind goes light offshore from the NW, and the ocean cleans right up, but the swell is still a pathetic 1ft. It’s a clean, knee-high dribble at best. Not worth getting the suit wet for, to be honest.
The one real standout in this whole 16-day window is looking like Sunday the 23rd of August. It’s still over a week away, so don’t book it in stone, but the models are pointing to something rideable. The swell picks up a little to 2ft from the East, and we get a proper offshore wind from the West. The energy is still weak, only 22, but it’ll be clean and lined up. Lowestoft is fairly exposed and inconsistent at the best of times, so this is a chance for a few fun ones if you’ve got a longboard. It won’t be big, but it’ll be the best we’ve seen in a while. The afternoon looks okay too, with a lighter cross-off, but the morning is the call.
After that, the plug gets pulled again. The last few days of the window, from the 24th to the 26th, are looking poor. We get strong and even gale-force offshore winds, but the swell has completely vanished, down to a foot or less. Clean but flat, frustrating. It’s a total blank run.
So, there you have it. One promising morning on the 23rd, and a whole lot of nothing else. For a spot that’s usually this inconsistent, it's not a huge surprise, but it doesn't make it any easier to take. Hang in there, keep an eye on that forecast for the 23rd, and maybe dust off the kiteboard for the rest of it.

Information about the Lowestoft Surf forecast
The above surf forecast table for Lowestoft provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lowestoft can be found by selecting the local surf guide option on the grey menu. Our Lowestoft 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 (Lowestoft) 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 Lowestoft 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.
Lowestoft is 1 km (1 miles) from the city of Lowestoft. If you plan a holiday in East Anglia, look for hotels and other accommodation in Lowestoft. Lowestoft has rooms for a wide range of budgets as well as car hire and transport links.
