Table - best surf conditions forecast for Knights over the next 16 days.
Alright, this is Rusty comin' at ya. Let's talk about what's on the table for Knights.
We've got a bit of a wild ride ahead over the next few weeks. The first real session worth paddling out for is Friday morning, July 10th. The water temp is sitting at 58°, which is about average for this time of year, so no nasty surprises there.
Friday morning, July 10th, is a solid start. We're looking at swell at 5ft, pushing in from the SSW, with a nice 15-second period, meaning plenty of energy behind it. The wind is light out of the N, so it's glassy, clean, and the break should be holding up nicely. The combined energy is sitting at 987, which is moderate wave energy, but it's gonna feel punchy. Afternoon sees a slight drop in size to 5ft, wind shifts to a light NW cross-off, and it stays clean.
Saturday morning, July 11th, we get a bit of a downer. The wind is howling out of the NW at 35 km/h, and while it's cross-off, the swell drops to 3ft. It's a bit of a washout for any real quality. By Saturday afternoon, the size jumps up to 10ft, but it's a short 10-second period, and the wind is trash – 35 km/h WSW cross-onshore, making it lumpy. Not what you want.
Sunday, July 12th, the swell is getting big—12ft in the morning and pushing to 15ft in the afternoon. The wind is onshore and cross-shore, so it's choppy and messy. The energy is through the roof, with the afternoon hitting 10184, but this is a case of too much of a bad thing. This is expert-only territory, and even then, it's not going to be pretty.
The whole week from Monday, July 13th, through to Wednesday, July 15th, is a write-off for paddle surfing. The swell stays massive, between 12ft and 15ft, with long 15-16 second periods, but the wind is all sorts of wrong. It's cross-shore, cross-on, and onshore. For a break that's a beach and reef setup, this is more of a kite-surfing scene than something for a regular surfer.
Now, the first real standout comes Thursday, July 16th. This is the one to circle. The swell drops to a manageable 6ft from the SSW, with a 14-second period. But the magic is the wind: light NNE offshore at 10 km/h in the morning, shifting to a light NW cross-off in the afternoon. The water will be clean, glassy, and the break should be peeling. The combined energy is 1396 (moderate). This is excellent for experienced surfers, and it's the best bet of the whole outlook.
Friday, July 17th, keeps the good run going. Morning brings 6ft of SSW swell, still at 16 seconds, with a light N cross-off. The afternoon drops to 5ft, and the wind stays clean. It's very good, but Thursday is the real standout.
After that, the weekend of July 18th through 19th is a bit of a comedown. Swell drops to 3ft to 5ft, and while the wind is decent, the energy is low (321 to 440). Sunday afternoon gets a bit of a bump to 6ft with a nice NNE offshore, so it's clean, but the period is short (10 seconds), so it won't have the same grunt.
Then we hit a gap. From Monday, July 20th, through to Wednesday, July 22nd, it's mostly poor. The wind is cross-shore and onshore, and the swell is either too small or too messy. There's a tiny window on Wednesday morning with 5ft from the S, but the period is a weak 8 seconds, and the energy is low (568). Not worth the drive.
The next real chance for a standout is further out. Thursday, July 23rd, afternoon sees a bump to 6ft from the SW, but the wind is cross-shore and lumpy. It's marginal.
But look ahead to Friday, July 24th. This is a promising, long-range call. The swell is 8ft from the SW, with a 14-second period, and the wind is a clean cross-off out of the NW at 25 km/h. The energy is strong (2804). This is one for the experienced crew. It's a bit of a gamble this far out, but if it holds, it could be the best of the second week.
Saturday, July 25th, is a drop-off again, with 7ft and cross-shore wind, so it's a fade-out.
So, to wrap it up: the best on offer is Thursday, July 16th at Knights. Get on it. The second best is the long-range call for Friday, July 24th, but keep an eye on it. For the rest of the time, you're either fighting the wind, the size, or the lack of energy.
This is Rusty, signing off.

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.
