Table - best surf conditions forecast for Knights over the next 16 days.


Alright, Rusty here. Let’s have a look at what’s coming up for Knights.

It’s a bit of a mixed bag, to be honest. We’ve got some serious size on the way, but the wind is going to be the big talking point. This is an advanced spot – a beach and reef setup – and it’s exposed to the south-southeast, which lines up with the swell direction. The water’s sitting at 59°F, which is about normal for this time of year, so no drama there.

The week kicks off proper on Wednesday morning, July 8th. That’s our first real shout. We’ve got a solid 8ft groundswell from the SSW with a long, powerful period of 18 seconds. That’s proper energy (3323) and with a light NE breeze blowing cross-off, it’s going to be clean. This is a wave for experienced surfers only – that size and that period means it’ll be plenty powerful and hollow. The trade-off with a long period swell like this is it might line up a bit straight on the beach sections, but on the reef it should have good shape. Crowds are a thing here, and with conditions like this, expect company.

Thursday morning, July 9th, drops a touch to 5ft from the SSW, but the period is still a meaty 15 seconds. The wind swings NNE and goes offshore. That’s the dream. Clean, lined-up waves for the experienced crew. It’s a little smaller, but the quality will be there.

Friday the 10th holds similar size, 5ft SSW with 15-second periods, but the wind goes a bit cross-off from the N. Still clean, still quality, but the energy drops a notch (987). A good session for those who know the wave.

Now, from Saturday July 11th, it gets ugly. The wind cranks up from the WNW and W, blowing cross and cross-on at 19 mph. The on Saturday afternoon a big 12ft swell from the SW arrives, but with a short 10-second period and a messy cross-onshore wind, it’s a write-off. It’s going to be lumpy, choppy, and not worth paddling out.

Sunday the 12th, the swell is still huge – 12ft to 10ft from the SW – but the wind is howling cross-shore at 16 mph. It’s just too big and too messy for this break. Kite surfers might be loving it, but for a paddle surfer, it’s a no-go.

Monday and Tuesday of the next week (July 13th and 14th) are a wash. We’re looking at 13ft swells from the SSW with strong cross-on winds. The energy numbers are enormous (over 7000) and it’s dangerous and blown out. Not for us.

We get a small window on Thursday morning, July 16th. The swell drops to 7ft from the SSW, and the wind goes light from the S (3 mph), but it’s cross-on. It’s marginal – might be worth a look if you’re desperate and the tide is right, but it’s not a standout.

Now, the real highlight of the whole run is Friday morning, July 17th. The swell is a manageable 5ft from the SSW, but the period jumps back up to 15 seconds, and the wind goes to a light NW cross-off at just 3 mph. The energy is solid (1670), and conditions will be clean. It won’t be as big as the early days, but for quality and surfability, this is the best session on offer. Then Saturday the 18th morning looks similar – 5ft, 14-second period, and a clean NW cross-off. Another good one.

After that, the wind ramps up again from the NNW into the third week, getting into the 25-31 mph range. The swell drops away, and by Monday July 20th, we’re down to under 3ft. The run of good surf is over.

Then, looking way out at Wednesday July 22nd, we see a massive 12ft SW swell with a 16-second period and glassy conditions from a light S wind. That sounds incredible, but it’s a long way out, so take it with a grain of salt. If it comes together, it’s an expert-only day of epic proportions. But for now, it’s just a promising idea on the horizon.

So, to sum it up: the first four days have some quality clean waves for advanced surfers, with Wednesday morning July 8th being the big, powerful kick-off, and Friday morning July 17th being the sneaky best session for clean, refined conditions. There are long gaps of blown-out, oversized swell in between, so pick your windows wisely.

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.
