G'day, Rusty here, your local surf reporter.

Alright, let's have a good look at what's on the cards for the next couple of weeks at Knights. The overall pattern is a slow start, then a big pulse of groundswell that's more for the experienced crew, before things get a bit messy with strong winds towards the end of the second week.

So, we've got nothing really happening until the morning of Sunday, July 5th. That's the standout of the whole run. We're looking at a solid 12 ft of SSW groundswell with a very long 17-second period. The combined energy is cranking at (7019), which is serious power. The morning is looking clear with an offshore breeze from the east at 9 mph. This is a classic Knight's set-up – a big, clean groundswell from the south-east. It's a beach and reef combo and fairly consistent, so expect some proper walls. The water temp is sitting at 59°, which is about average for this time of year. But listen, 12 ft is a big wave, so this is strictly for advanced surfers only. That Sunday afternoon is still pumping with 10 ft swell, but the wind swings cross, so the morning session is your window.

The Monday and Tuesday following that (July 6th and 7th) are still decent, with good cross-off winds and dropping swell from 7 ft down to 5 ft. The energy is down to a moderate (1042) by Tuesday morning, but with a long 16-second period, it will still have plenty of push. A good option for the experienced lads to get some fun ones before it starts to get a bit crowded – it can get busy here.

The next real highlight pops up on the morning of Wednesday, July 8th, with a clean 8 ft SSW swell, very long 18-second period, and a beautiful offshore wind from the north-east at 9 mph. The energy is sitting at a strong (3361). That's a powerful, clean groundswell – a proper morning session for the advanced crew.

After that, the swell backs right off into the following week. The morning of Saturday, July 11th is a write-off – just small, weak 3 ft stuff with a lot of wind.

Then the second week gets gnarly. From Sunday, July 12th right through to Tuesday, July 14th, the models are showing big, raw, and ugly conditions. We're talking 13 ft waves on the morning of July 14th from the SSW, but it's getting slammed by strong onshore winds. That’s just dangerous and messy. Not for paddling; that's a kite surfer's dream, not ours.

There's a glimmer later on. The Thursday afternoon of July 16th shows a solid 10 ft SSW groundswell with a 16-second period and cross winds, the energy is strong at (5585). But then, looking further ahead to Friday, July 17th, things get really interesting. The morning shows 12 ft and the afternoon shows a whopping 15 ft, both from the SSW with a 15-second period and cross-off winds. The energy numbers are huge – (4820) and (9006). This is some serious power. However, we are a long way out, so consider this a promising but uncertain possibility. The 15 ft is massive and only for the most seasoned pros at a spot like this.

So, in short: the absolute pick is the clean, powerful groundswell on the morning of Sunday, July 5th. The morning of Wednesday, July 8th is another beauty. The weekends in the second week look big and have potential, but we'll need to keep an eye on the winds.

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.
