Updates in hr min s Forecast update imminent
Alright, let’s talk about what’s happening at Knights. This is an advanced, exposed beach and reef setup that needs a clean, light wind to really fire. The water’s sitting at 59°F right now, which is only just slightly cooler than average for this time of year – nothing out of the ordinary.
We’ve got a decent window opening up from Monday the 6th. Starting off the week, Monday morning brings 7ft of SSW groundswell with 14-second period and a light NE cross-off breeze. The combined energy is strong at 1748, so there’s plenty of push. Tuesday keeps that same SSE swell direction, with 5–5ft and a period that stretches to 16 seconds. The wind stays cross-off from the NE and ENE, keeping things clean. The energy is still moderate to strong, around 1042–1202.
Wednesday the 8th is the standout of the first week. Morning sees 8ft from the SSW, with a very long 18-second period. Wind is straight offshore from the NE at 6 mph – that’s glassy. The combined energy hits 3323, strong stuff. This is a proper groundswell. Given the long period, it’ll be better shaped and more drawn-out at this reef point, but beach breaks might see it breaking a bit too straight. For an advanced surfer here, it’s going to be clean and powerful. Thursday and Friday still offer clean 5ft with light offshore or cross-off wind, but the energy drops a bit – still worth paddling out.
Then we hit a rough patch. Saturday the 11th turns windy with NW gusts at 22 mph, and by afternoon a cross-shore with rain makes it messy. Sunday the 12th is a write-off – 12–13ft of onshore wind slop, fresh cross-onshore, energy blowing out to 2974–5769, but it’s just nasty. Monday the 13th has 15ft of swell, too big for even this spot – that’s expert-only territory and the wind is cross, so the set-up looks more like a kite day than a paddle session.
The second week is patchy. Tuesday the 14th sees a 6ft SSW groundswell with 18-second period and light cross wind, but the energy is high at 3069. That Wednesday and Thursday have 8ft+ but with cross-onshore wind, not clean. Thursday the 16th morning is worth a look – 12ft from the SSW with 16-second period and light offshore NE – that’s clean but big for all but the best. The afternoon shows 10ft with a cross-off wind and excellent conditions for experienced surfers. Friday the 17th backs down to 7ft with light cross-off and clean waves, energy moderate.
By the second weekend (Saturday 18th and Sunday 19th), the wind picks up again – strong to near-gale on Sunday – and the surf turns poor with rain and onshore flow. Monday the 20th is still windy and choppy. Tuesday the 21st looks rough with heavy rain and onshore SW winds.
So if you’re picking the best of the run, Wednesday the 8th morning is your top call: clean offshore wind, strong 8ft groundswell, very long 18-second period, and high energy. Thursday the 16th afternoon is a solid backup with 10ft and clean conditions. The rest of the second week is more of a wait-and-see, especially with those big swells and changeable winds.

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.
