The Lowdown

Alright, surfers, Rusty here again, but this time in feet and miles.

We’ve got one spot on the menu for the next 16 days: Knights. It’s a beach and reef set-up that’s exposed to the swell, so it’s on the front line for whatever rolls in. The water temp is sitting right around average for this time of year, so nothing wild there.

The window opens up on Thursday, the 27th of August. We’ve got a patchy start but it’s worth the wait. Wednesday the 26th is a write-off with marginal conditions and a cross shore breeze messing things up, so I’d give it a miss.

Thursday morning, the 27th, sees us with a clean 4 ft SSW swell rolling in, period at 14 seconds, and a light cross-off breeze. The energy is sitting at 713 (moderate) – it’s not huge, but it’s clean and rideable. The afternoon picks up to 5 ft from the SW, with the same light cross-off wind, and the combined energy jumps to 1097 (still moderate). That’s the first real standout of the run – clean, lined-up waves for experienced surfers.

Now, if you want the best of the best, you’re looking at Friday morning, the 28th of August. This is the true standout. We’ve got 6 ft of SSW groundswell with a long 17-second period, glassy conditions – absolutely zero wind – and the combined energy is reading 2023 (strong). That’s proper, powerful, clean surf. The long period means it’ll be a bit more drawn out, but the shape at a reef/point set-up like this should be excellent. The only catch is that it’s likely to be too big for beginners, so advanced surfers only.

Saturday the 29th drops off a little – 5 ft in the morning with a cross breeze, and the afternoon goes onshore and weak. Not worth the paddle.

Sunday the 30th, the morning cleans up again with a 4 ft SSW swell, 12-second period, and a light offshore ESE breeze at 3 mph. Clean lines, energy at 882 (moderate). It’s a solid session for the more experienced crew.

Monday the 31st of August is another belter. Morning sees 8 ft of SSW groundswell at 16 seconds, with a clean offshore NNE breeze at 6 mph. Combined energy is 3386 (strong). This is proper big, clean, and powerful – expert territory only. The afternoon stays solid with 8 ft and the same clean conditions.

Tuesday the 1st of September, the wind picks up to 22 mph in the morning and 19 mph in the afternoon. The swell is still there (5 ft to 5 ft), but the fresh breeze is going to put a chop on the surface. I’d give it a miss.

From the 2nd of September through to the 4th, we’ve got a mix of onshore wind and cross-shore chop, but the swell stays around 4 ft to 7 ft. Nothing to rave about. The 4th of September has a clean morning with 8 ft SSW swell, 15-second period, and a light offshore wind – that’s a solid pick for the experts.

The 5th of September brings 10 ft SSW swell with a 17-second period, but the wind is cross-shore and moderate, so it’ll be a bit lumpy. Still, the energy is huge at 4947 (very strong). That’s a big, powerful, messy wave – more for the chargers.

The 6th and 7th of September are poor – onshore winds, windswell, poor conditions. Not worth the salt.

The 8th of September looks promising again – 8 ft SSW groundswell, 16 seconds, and light onshore wind at 3 mph. The energy is 3345 (strong). It’s a clean, powerful, big swell day. The 9th of September, though, the swell hits 12 ft with 16-second period, and the energy is a massive 11167 (very strong). The forecast says it’s too big for this break, so unless you’re a tow-in specialist, stay out.

The 10th of September, the swell drops back to 8 ft, but the wind is cross-onshore, so it’s messy.

Overall, the standout is Friday morning, 28th of August – glassy, 6 ft, 17-second SSW groundswell, strong energy, and clean. Monday the 31st of August is also a top-tier day for the experts. Crowds are often a factor at Knights, so get in early.

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.
