The Lowdown
Alright folks, Rusty here. We’ve got a bit of a wild ride ahead, so let’s get straight into it.
First up, the water temperature at Knights is 57°, which is about 1° cooler than average for this time of year – nothing too crazy, but you’ll feel that slight chill on the morning paddle.
The forecast starts off with a bang, but it’s looking like a waiting game for the first few days. Tuesday the 28th is a write-off, mate. We’ve got a 5ft SSW swell bumping into a strong cross-on wind, making for really poor conditions. The combined energy is still moderate (1448), but it’s messy and not worth your time. The afternoon gets even bigger at 10ft, but the wind stiffens, making it a total no-go for paddle surfing.
Wednesday the 29th is a different story in terms of power, but it’s a case of too much of a good thing. The swell is massive – 15ft in the morning with 16-second periods from the SSW. The combined energy is through the roof (8860), but it’s simply too big for this break. Unless you’re a pro and have a death wish, stay on the beach. The afternoon drops to 12ft, but still, it’s for experts only and the wind is still cross-on.
Now, Thursday the 30th is where things get interesting for the experienced crew. The morning offers a solid 8ft SSW swell at 13 seconds with glassy conditions. The wind is dead calm, light air, and the water is clean. The combined energy is strong (2153), and this is a standout for advanced surfers. The afternoon drops to 6ft, but the wind goes onshore, making it more marginal.
Friday the 31st is a real treat. The morning brings a clean 5ft SSW swell with a light offshore wind from the NNE, perfect for those long, clean lines. The period is 12 seconds, and combined energy is moderate (726). The afternoon stays clean with a 5ft swell and light cross-off winds. This is a solid pick for a fun session with less crowd pressure.
Saturday the 1st of August holds clean, 6ft waves in the morning with a cross-off breeze, but it’s a bit more marginal with the tide. The afternoon picks up to 8ft with a 17-18 second period, offering some real power (3375 combined energy), but the wind picks up a bit. It’s still clean, but the size pushes it towards experienced surfers.
Sunday the 2nd is back to the big stuff. The morning is a 8ft wall of onshore slop, so forget it. The afternoon is 12ft again, too big for the spot.
Monday the 3rd of August brings a clean 8ft swell in the morning with a cross-off wind – excellent for experienced surfers (2908 combined energy). The afternoon is a bit more mixed with a cross-shore wind.
The rest of the week looks promising. Tuesday the 4th, Wednesday the 5th, and Thursday the 6th all offer clean, smaller swells with offshore winds. Wednesday the 5th is a standout with 4ft to 6ft SSW swells, 14-18 second periods, and gentle offshore winds. The combined energy is solid (1196-1980), and the quality is excellent for experienced surfers.
Friday the 7th is smaller, with 2ft to 3ft swells, but still clean. The weekend of the 8th and 9th sees a return of larger, clean swell (7ft on Saturday morning) with cross-off winds, but it’s a bit further out and less certain.
Looking further ahead to the second week, the pattern holds. Monday the 10th and Tuesday the 11th offer clean, medium-sized swell with cross-off winds. Wednesday the 12th of August is a massive spike again – 15ft with a 14-second period and strong winds, but it’s too big for paddle surfing.
Overall, the best windows are Friday the 31st of July for a chilled, clean session, and Wednesday the 5th of August for the best combination of size, period, and perfect offshore winds. If you’re an experienced surfer, Thursday the 30th of July in the glassy morning is your moment.
Keep it salty.
Rusty.

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