The Lowdown
Alright, Rusty here. Let’s take a look at what’s cookin’ for the next couple of weeks at our local spot.
Honestly, it’s a tough stretch. For most of the next 16 days, we’re lookin’ at a whole lotta nothin’. From August 11th all the way through the 25th, the surf is consistently poor. That’s a solid two-week gap with no real waves to speak of. The swell is tiny, the wind is messy, and the energy just isn’t there. If you’re itchin’ for a paddle, you might as well take up somethin’ else for a while ‘cause this stretch is a write-off.
We finally get a flicker of somethin’ worthwhile right at the very end. On Wednesday mornin’, August 26th, things finally wake up. A solid 7ft swell rolls in from the NNE with a period of 8 seconds. The combined energy jumps up to 749, which is strong and will pack a punch – that’s proper wave power. But here’s the catch: that swell height is over 5ft, so it’s already out of the beginner zone. It’s pushin’ 8ft, so this one is really for experienced surfers only, and it’ll be a handful. The wind is a gentle breeze from the SW, which is cross-offshore and clean. That means the surface will be smooth, no chop. That’s a major positive for a break like Lowestoft which is fairly exposed. The water temperature is about average for the time of year, so nothin’ weird there.
This is the only real standout in the whole window, and it’s nine days away, so the long-range call is promising but not a guarantee. It’s a rare break of good conditions after a long, flat spell. If it holds, it would be the best session by a mile.
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.

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.
