The Lowdown
Right, I’ll be straight with you… the next 16 days at Lowestoft are a tough watch. We’ve got nothing pushing in with any real punch, and the wind’s playing games most of the time. You’re looking at a long gap of flat to tiny, messy waves right through Thursday the 13th of August to about Tuesday the 19th of August. It’s small, it’s choppy, and frankly, not worth paddling out for.
Then things get a bit more interesting around Thursday the 20th of August. The energy picks up to a moderate 216 (moderate wave energy) with waves hitting 5ft out of the north, period around 8 seconds. But look, that’s a cross-shore wind on it, and the comment says poor surf conditions. It’s gonna be a bumpy, choppy mess. Not a total flat spell, but not what you’d call good.
Friday the 21st of August is similar – swell height 5ft, north swell, with a combined energy of 391 (moderate to strong wave energy). But again, winds are cross to cross-onshore, giving us that moderate cross-chop. It’s got some push, but it’s not clean.
Now, if you’re an expert and you don’t mind a challenge, the morning of Thursday the 27th of August has a 5ft south swell coming in with a fresh offshore wind from the southwest. That’ll clean it right up. The water’s about average for this time of year, so no drama there. It’s a cross-off wind, but it’s still clean. The swell period’s short at 6 seconds, so it’ll be a bit weak and won’t hold together too well. The afternoon of the 27th of August, we get a 5ft south swell with a 35 km/h offshore wind from the WSW. That’s the best-looking window in the whole outlook – fresh offshore and clean. That’s the one day I’d actually get excited about. But that 5ft and short period means it’s for the experienced crew only.
As for the rest, there’s a few clean mornings, like the 18th and 19th of August, but the swell’s just a dribble – 1ft to 2ft. Not worth the wetsuit.
So the standout is Thursday the 27th of August afternoon. Clean, offshore, and a bit of size. The rest of the 16 days? Mostly a rest for your arms.

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.
