The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this 16-day window for Lowestoft is a tough one. The swell window is pretty closed, with most of the forecast showing flat, weak conditions.
We are looking at a blank run for the first few days. Honestly, the first real chance of something surfable doesn’t show up until Sunday morning, the 23rd of August. Even then, it's not much to write home about. The waves are tiny, and the quality is ordinary. You’ll be scratching for scraps here.
Let’s run through it. The strongest push of the week happens on Tuesday the 25th, with a pulse of swell from the east. We see wave energy hitting moderate levels, peaking at 181 (moderate energy Tuesday morning) and 114 (moderate energy Tuesday afternoon). The swell height gets up to about 5 ft, with a period of only 6 seconds. That short period means the waves will be quick, fat, and weak. With the wind howling from the east at 19 mph and turning onshore, it’s going to be a complete mess. That setup is far better suited for a kite than a paddle.
Now, if you are absolutely desperate, the least-bad option is a brief window on Sunday morning the 23rd. We get a tiny windswell, 3 ft from the NNE, with an 8-second period. The energy is weak at 76 (weak wave energy). But, the wind is glassy, with a light westerly breeze. That will make the surface clean. It's a beginner-level option for sure.
After the 25th, the swell collapses. The rest of the outlook is packed with days of 0.3 ft to 1 ft surf and cross-off or offshore winds. While the wind is clean, there is simply no ocean energy to work with, with readings often dropping to single digits (weak wave energy). The water temp is about average for the time of year.
So, the verdict: Sunday morning the 23rd is your only real shot at a surf, and it’s a low-quality one. The rest is a skunk. This one is a waiting game.
Always,
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.
