Alright, Rusty here, let's get into it.
We’ve got a solid run of surf coming up at Knights (beach and reef). The water's sitting at 59°F, which is about average for this time of year, so no surprises there.
The first real call is Monday morning, July 6th. We’re looking at a clean 7 ft swell from the SSW, with a nice 14-second period. The wind is a light cross-off from the NE, so it’s going to be clean. The energy is strong, with a reading of 1748. This is advanced territory, but for those guys, it’s a good session. The light breeze keeps it tidy.
Monday afternoon holds up well, dropping slightly to 6 ft, still clean and cross-off. Good surf.
Tuesday, July 7th, the swell drops a bit to 5 ft, but the period stretches to 16 seconds, which is a proper groundswell. The wind stays cross-off and light. The energy is still moderate (1042). Good for a longboard or a step-up.
Now, Wednesday, July 8th, is the standout. The morning brings a 8 ft swell from the SSW, with a very long 18-second period. This is proper groundswell, and it’s packing a punch (energy of 3323). The wind is a gentle cross-off, so it’s clean. This is the best of the bunch for the week, but it’s for experts only. The long period will make it line up well on the reef, but it might be a bit too straight for the beach break sections.
Thursday morning, July 9th, is a hidden gem. The swell is 5 ft, but the wind turns offshore from the NE, light and clean. It’s a smaller, cleaner window with a solid 15-second period. Energy is still decent (924). This is the call for the average surfer looking for a good ride.
From Friday afternoon, July 10th, things start to go south. The wind picks up, and by Saturday, July 11th, it’s a fresh breeze with poor conditions. That lasts through Sunday, July 12th, where we get a lumpy, cross-shore mess with a short-period 10 ft swell. This is a kite surfer's setup, not a paddle surfer's.
Monday, July 13th, and Tuesday, July 14th, see big, messy, cross-onshore swells. The energy is huge (over 4000), but the wind just ruins it. It’s a washout.
The next real hope comes on Thursday, July 17th. The morning is glassy, with a 5 ft SSW swell and a 13-second period. The wind is a slight air from the NNE. This is a clean, glassy window. It’s a smaller day, but it will be a good one for a relaxed session.
Saturday, July 18th, is also clean with a small, 4 ft swell, but good period (16 seconds) and light cross-off winds. Nice, but small.
The long-range forecast for the week of July 21st shows a massive 13 ft swell from the SW with a 17-second period, but the wind is a strong cross-off. The energy is at 8607. This is just too big for this break, and it’s only for the most experienced, if anyone. That’s a shrug and a miss.
So, the pick of the week is Wednesday, July 8th, morning, for the big, powerful groundswell. For a more manageable, clean session, grab Thursday morning, July 9th, or the glassy morning on July 17th.
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.
