The Lowdown
Alright, Rusty here. Let’s have a look at what’s going on for Lowestoft.
Right, straight up, the next couple of weeks are looking grim. The waves are tiny, the energy is pathetic, and there’s just no reason to get excited. We’ve got a long, dry stretch ahead with almost nothing worth paddling out for. For Lowestoft (United Kingdom), the outlook is a tough one.
The first week is a total write-off. From the 17th of August onwards, we’re looking at waves below 0.3m (less than 1 ft) with weak combined swell energy (just 3 to 12). The water temperature is a notable 68°F, which is a good 5°F warmer than usual for this time of year, but that’s about the only bright spot. The winds are mostly offshore or light, but with no swell to push around, it’s just a flat, clean lake. You could almost kite surf if you had to, but there’s nothing for a paddle surfer.
Things try to pick up a little around the 21st and 22nd of August. The swell height bumps up to around 0.9m to 1.0m (3 ft to 3 ft) from the NNE, but the period is short (6 to 8 seconds) and the wind is a messy cross-shore. Combined energy climbs to a moderate 54 to 131, but it’s all lumpy and chopped up. It’s not surfable quality. The 23rd and 24th see the swell drop again, with the same poor cross-shore or cross-onshore winds. It’s just not happening.
After that, from the 25th of August all the way through to the 1st of September, we’re back to flat or near-flat conditions. Swell heights are under 0.5m (2 ft), often zero, and combined energy is in the single digits. There’s no standouts here, no hidden gem. The forecast is consistent: nothing worth your time.
Forget it. This is a long, blank run. It happens here sometimes, and this is one of those times. Stick to the skatepark or get the fishing gear out.
Rusty.

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.
