The Lowdown
Right then, let's have a look at what's on offer for the Lowestoft region. To be straight with you, it's been a tough run. For the next ten days or so, there's barely a whisper of proper swell, and most of what does show up is tiny, weak, and often blown out. It's one of those stretches where the ocean just seems to have switched off, and the consistent options are few and far between. You'll be looking at a lot of flat, clean but useless days, especially through the middle of the period. Patience is the name of the game here.
Let's talk about the water temp first. Over on the 12th of September, the water is sitting at 66°F, which is a solid 4°F warmer than usual for this time of year. That's notable, feels like summer's hanging on a bit longer.
Now, the only real flicker of life comes much later. The period from the 22nd of September onwards starts to build some very modest, weak energy. On Tuesday the 22nd, the swell height creeps up to 2ft from the north, but the wind is a cross-onshore, so it'll be lumpy. The real standout window, and I'm calling it that with caution, is the morning of Wednesday the 23rd of September. The swell is still tiny at 2ft from the north, but the wind goes glassy. Absolutely flat calm. If you're on a log or a funboard, that's your window for some clean, if small, little crumbly waves. The combined swell energy is only 35, so it's very weak.
For the rest of that final week, the 24th and 25th see a slight bump in size, up to 2ft, and the wave energy climbs into the moderate range with a value of 116 on the 25th. But the wind swings onshore or cross-onshore, making for choppy, messy conditions. It's more of a kite surfing setup than a clean paddle surfing one, especially with the short periods around 8-9 seconds.
So, in summary: don't hold your breath for the next week and a half. The single, honest-to-goodness standout is the glassy Wednesday morning on the 23rd, but only if you're happy with ankle-to-knee high waves. After that, the promise of slightly more size is ruined by the wind. It's a tough block for the area, but forecasts can change.

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.

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.
