The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' at Knights. It's a bit of a slow burner, but there's some real magic waiting if you're patient.
The first few days of the outlook are pretty average. Sunday the 26th and Monday the 27th are a write-off, to be honest. The swell is there, around 5ft to 6ft from the SSW, but the wind is messy and conditions are just marginal. You'd be fighting a cross-shore bump. Not worth paddling out for.
Tuesday the 28th is a total no-go. Onshore winds are howling and we've got a big, lumpy, rain-soaked mess. The swell energy is climbing to high levels (3612), but it's just ugly. Wednesday the 29th is a different beast entirely, but it's a beast for experts only. We're looking at a big SSW groundswell pumping in at 13ft with a 16-second period, and the combined energy is massive (7249). That's a big, powerful ocean, boys. If you're not a seasoned charger at Knights, stay on the beach for this one. The wind is onshore, so it'll be a bumpy, heavy drop.
Thursday the 30th is still a bit of a mix, with the swell dropping back to 7ft – 8ft. The wind is light and onshore, so it's still not the cleanest. You'll get a wave, but it's not the standout.
Now, listen up. Friday the 31st of July into the weekend is where it's at. Friday morning the wind drops to nothing, absolutely glassy. The swell is still a solid 5ft from the SSW with a 12-second period. The energy is moderate (861), but those glassy, lump-free faces will be a dream. That's a serious session right there.
Saturday the 1st of August is the best on offer. The morning is clean with a light offshore breeze from the north and a 5ft SSW groundswell with a very long 17-second period. The energy is building (1189), and the water is 58° – that's about normal for this time of year, nothing freaky. Those long lines from the south will wrap in perfectly, giving you some proper, long, open-faced waves. This is for the experienced crew, as that long period can make the sets a bit tricky, but the quality is top shelf. The crowds are often up here, so get in early.
Sunday the 2nd of August keeps the fun going. We've got a clean 6ft – 6ft SSW swell with offshore winds in the morning. The energy is still moderate (1379), and the conditions are clean. It's a fantastic follow-up day.
The second week gets a bit more unruly. Monday the 3rd and Tuesday the 4th see a jump in swell size, up to 10ft or more, with strong energy (3013). The wind is cross-off to cross-on, so it's a bumpy, chunky mess for the most part. The wave heights are getting up into the "expert only" territory for sure.
Wednesday the 5th of August sees a drop in size back to 6ft – 6ft, but the wind is tricky. Thursday the 6th of August is a highlight of the second week. Morning offshore winds from the north, a solid 8ft SSW swell with a 14-second period, and excellent conditions for experienced surfers. The energy is strong (2787). That's a proper session. Friday the 7th is similar but with a bit more wind. The weekend of the 8th and 9th fades fast, dropping to small, weak, and messy surf. The energy is gone (811), and the wind is no good.
So, the standout? No question, it's Saturday the 1st of August. Solid, clean, long-period groundswell with light offshore winds. That's the one you circle on the calendar. Friday the 31st of July is the runner-up for that glassy, early morning magic. And for the second week, Thursday the 6th of August offers a solid, powerful session for the experts.
Rusty out.

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.
