Alright, Rusty here. Let's chew the fat on what's coming down the line.
First off, don't bother paddling out just yet. There's a bit of a dry spell. The first real chance to get wet kicks off on Tuesday morning, July 7th at Knights (beach and reef). We're looking at a 5 to 5 foot SSW swell, with a very long 16-second gap between the waves. The water's sitting at about 59°, right where it should be for the season. This one's not for the beginners though. With a cross-offshore breeze (NE to ENE) keeping it tidy, it's got moderate to strong energy, but it's built for the experienced crew.
Wednesday the 8th is the absolute standout of the first week. The swell muscles up to 8 feet in the morning and hangs around 7 feet in the afternoon, still pumping out of the SSW. That 17 to 18-second period is a pure groundswell. The combined swell energy is very strong. Wind stays a friendly cross-offshore from the NE and ENE, so you're looking at clean, lined-up walls. This is expert territory – anything over 8 feet is a big boy's game, and we're right on the edge. Expect a crowd, because it's 'often' busy here.
Thursday the 9th is another solid option, especially the afternoon. The swell eases to 5 feet, but the wind goes glassy from the NE. That's a massive plus – clean, silky faces on a long-period SSW swell. Perfect for the advanced surfer who wants quality without the full brunt of Wednesday.
The weekend (July 11th and 12th) goes pear-shaped. Saturday the wind swings onshore and the swell gets short and choppy. Skip it. Sunday the 12th sees the swell jump to 13 feet, which is just too much for this break. The forecast says it's too big. A hard no.
Heading into the second week, things get less certain. Monday the 13th stays big and onshore. Not good. Tuesday the 14th is still on the large side (10 feet) but with lighter wind, though it's still onshore. It's marginal.
Now, a real bright spot appears on Wednesday the 15th of July. Morning shows a 8 foot SSW swell with glassy conditions. That is a very, very clean setup. The swell energy is strong. This is expert-level size, but with that glass, a dawn patrol could be magic. The afternoon gets a cross-onshore bump, so make it an early one.
Thursday the 16th looks beautiful. The swell drops to a more manageable 7 feet in the morning and 6 feet in the afternoon, with a nice 13 to 14-second period. The wind is offshore (NNE) in the morning and goes glassy (ENE) in the afternoon. The energy is moderate to strong. That's a top contender for the second week.
After that, the outlook gets fuzzy. There's a smaller window on Friday the 17th with 3 to 5 feet of SSW swell, but it's lighter. Then, from Saturday the 18th, we see a run of larger SSW and SW swells (7 to 12 feet) but paired with strong NNW and W winds. By Monday the 21st, the swell is back over 12 feet, making it another "too big" scenario. The forecast for that far out is a coin flip.
So, the bottom line: Wednesday the 8th is the big dog of the first week for power and clean lines. Thursday the 16th is your best bet in the second week for quality, manageable size and glassy conditions. Both spots are for experts only.
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.
