The Lowdown
Alright, let’s be honest—this is a rough stretch. We’re looking at a solid week and a half of nothing at Joss Bay (Thanet). Flat, gutless, and mostly just wind ripples. The only warm thing is the water, sitting at 20°, which is well above normal for this time of year. That’s about the only highlight.
The first real swell arrives on Monday, September 28th, but it’s not the kind you’ll write home about. A 1.7m northeast swell with a period of 6 seconds—that’s short-period windswell, which means it’ll be disorganised and quick to close out. Combined energy hits 217 in the morning, which is moderate, but the onshore breeze will chop it up pretty fast. By afternoon it’s down to 1.5m and lumpy, with energy at 148.
Tuesday the 29th keeps the energy at 149 and 165 through the day, swell around 1.5m to 1.6m from the east-northeast, but again—6 second period and onshore winds. It’s going to be messy, walled up, and hard to find a clean face. For a beach break like this, that’s not ideal. Honestly, this one looks better for a kite than a paddleboard.
So, bottom line: two weeks of flat, then a couple of days of average, wind-affected waves. The best window is the morning of the 28th—biggest swell and most energy, but don’t expect anything glassy. It’s a “get out if you’re desperate” kind of deal. Forecasts can change, but right now I wouldn’t be holding my breath for anything epic.
Keep it salty, and I’ll see you out there when it’s worth it.

Information about the Joss Bay Surf forecast
The above surf forecast table for Joss Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Joss Bay can be found by selecting the local surf guide option on the grey menu. Our Joss Bay 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 (Joss Bay) 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 Joss Bay 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.
