The Lowdown
Alright, I’m looking at the numbers for Lowestoft, and honestly, I’ve got to level with you – it’s a quiet stretch. We’re talking about a full 16-day window starting now, and for the first several days there’s just nothing worth paddling out for. The swell is tiny and weak, the wind is mostly messy, and the water temperature is sitting around 68°F, which is a good 5°F warmer than usual for this time of year – that’s pretty notable, feels more like a mild autumn bath than a late summer North Sea dip.
The first real hint of something happens on Saturday, 22 August, when the swell pushes up to 3ft out of the north-northeast. But the wind is cross-onshore from the northeast at 16 mph, making it choppy and lumpy. The combined energy is still only 69, which is weak, and the period is just 6 seconds – short, weak, windswell. It’s not going to be a pretty wave. By Sunday afternoon, 23 August, the swell height drops to 3ft, period up to 8 seconds, but the wind is even stronger at 19 mph from the northeast, fresh cross-onshore and lumpy. Combined energy hits 81, still weak. Not one for the logbook.
The cleanest conditions we see in the whole run come on Tuesday morning, 25 August, with a light cross-onshore from the southeast and swell around 2ft – but it’s tiny, with a period of 7 seconds and combined energy at 34. That’s a session for a foamie and no expectations.
The only time we get offshore winds and some consistency is around Wednesday, 27 August, through to Friday, 29 August. On Wednesday morning the wind is offshore from the west at 16 mph, with a 1ft north-northeast swell at 9 seconds and combined energy at 25. Clean, but tiny. Friday morning, 29 August, sees offshore from the west-northwest at 12 mph, again 1ft from the north-northeast, 6-second period, energy 15. Glassy and clean, but barely a ripple.
Overall, there’s no standout here. Lowestoft is inconsistent at the best of times, and this 16-day window is a flat, wind-affected, low-energy run. If you’re desperate for a splash, the cleanest moments are Wednesday 27 August morning and Friday 29 August morning, but you’ll be paddling for ankle-biters. Otherwise, it’s a blank spell – the sort that happens here from time to time. Forecasts can change, but right now, it’s a waiting game.

A general guide to surfing at Lowestoft can be found by selecting the local surf guide option on the grey menu.

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.
