The Lowdown
Alright folks, Rusty here. Let’s be straight with you – for this stretch of the Kent coast, we’re looking at a pretty grim run of surf for the first week and a half. The whole forecast period is 16 days, and there’s a big gap of nearly two weeks with nothing really worth getting wet for. The first hint of any kind of movement comes much later.
The first notable shift is on Saturday, the 1st of August. We’ve got a small pulse of swell arriving, but the conditions are a bit of a mixed bag. The morning at Joss Bay will see a north-easterly wind, which is a bit cross-onshore, making it look lumpy. The swell is 4ft from the NE, but the wave energy is weak, only registering 87. Still, by the afternoon, things clean up nicely. The wind swings to the west-northwest, giving us a clean cross-off breeze. The swell drops a fraction to 4ft, also from the NE, with light energy (76). It’s the best we’ve got, but it’s very ordinary. You’ll be fighting for scraps, but it’s surfable.
The water temperature at Joss Bay is a massive 68°, which is 7° warmer than normal for this time of year. That’s a very unusual anomaly, so you’ll be surprised how warm it feels out there.
After that, the next window is Monday, the 4th of August. The morning looks passable at Joss Bay, with a 4ft NE swell and a clean cross-off wind from the southwest. The energy is still just moderate at 98. The afternoon sees the swell drop to 3ft from the east-northeast with a light cross-shore breeze, making it small and clean. But again, it’s not going to get the heart pumping.
The only other flicker of hope is on Tuesday, the 5th of August. The morning has a 1ft NE swell, barely a ripple, but the wind is a moderate cross-shore, making it messy. The afternoon cleans up with a strong cross-off from the southwest, but the swell is gone at 1.0ft from the NE. The energy is down to 4, so it’s flat.
For the rest of the 16 days, it’s a write-off. Joss Bay is an inconsistent spot, and this is a classic example of a blank run. Don’t hold your breath. While the offshore winds come through on a few afternoons, the swell just isn’t there to back it up. The setup looks more like a kite surfing day than a proper paddle session when the wind picks up.
Rusty.

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.
