The Lowdown
Alright, let's get real for a sec. I've had a look at what's coming up for Lowestoft, and I'll be straight with you—it's pretty grim. There isn't a single day in this whole 16-day window that I'd call good surf.
We're stuck in a bit of a flat spell here. The water temps are sitting at about 69°, which is much warmer than normal for this time of year—makes for a nice dip, but you're not gonna be doing much paddling on a wave.
Looking at the first few days, right from Thursday, August 13th, we've got tiny, weak windswell from the east. That 2 ft is pretty much nothing, and with the 4-second period and onshore wind, it's just a mess. This pattern sticks with us for over a week. The swell heights barely register, and when they try to pick up, the wind just ruins it. There's a long stretch here of tiny waves and onshore or cross-shore breezes. Not worth looking at.
Even when we get to the 23rd and 24th of August, the swell starts to build, hitting 5 ft on Monday the 24th with moderate wave energy (169), but again, the onshore winds are strong, blowing straight in from the east at 19-22 mph. That onshore wind is a killer for quality. The period is short too, around 6 seconds. It's lumpy, choppy, and just plain unappealing for a paddle surfer. Honestly, with that kind of wind and swell, it's a setup that looks more interesting for kite surfing than paddle surfing.
The biggest push comes on Wednesday, August 26th, with a 6 ft swell from the NNE and a period of 7 seconds, carrying strong wave energy (279). But again, the cross-onshore wind from the NE is howling at 19 mph, making it fresh, lumpy, and messy. This is borderline too big for beginners, but for anyone else, it's just not clean enough. After that, it just fades back out into weak, onshore slop.
To be honest, there isn't a standout session in the lot. It stays poor throughout the entire forecast. There are simply no recommendations for a surfable wave here. A blank run like this does happen in these parts from time to time, so don't let it get you down. Forecasts can change, but right now, I wouldn't even bother loading the boards.

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.
