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


Alright folks, Rusty here. Let’s have a look at what’s on the cards for Knights over the next couple of weeks.

Right off the bat, we’ve got a bit of a wait. The first few days are a write-off – Saturday the 11th and Sunday the 12th are a mess. Saturday morning is showing some 3ft swell, but it’s weak and messy with a fresh cross-offshore breeze, and the water temp is sitting at 58°, which is about average for this time of year. That afternoon, the swell jumps to a massive 10ft, but it’s onshore and lumpy – not worth paddling out. Sunday the 12th is worse. The swell is huge, over 12ft and up to 15ft, with cross-shore winds. The energy is through the roof (moderate wave energy in the 623 range, and then huge 3540 and 10205 readings), but it’s just too big for this spot. A real shame.

Monday the 13th keeps that same pattern. Still pumping 13ft of long-period groundswell (16 seconds) from the SSW, but the wind is cross and the wave energy is massive (over 6900). It’s an expert-only game if you’re even thinking about it, but honestly, the setup is more interesting for kite surfing than paddle surfing right now. Tuesday the 14th is similar – 13ft and 12ft, but the wind gets cross-onshore and then onshore, making it a no-go.

Now, here’s where it gets good. Wednesday the 15th is the standout. The swell drops to a more manageable 8ft, and the wind goes glassy from the north in the morning. That’s a serious positive. The wave energy is still strong (2358), but it’s a clean, glassy morning. This is the best on offer – for experienced surfers only though, as 8ft is still a hefty wave. Thursday the 16th is also a beauty. The swell is 6ft, with glassy conditions in the afternoon and clean, cross-offshore winds in the morning. Friday the 17th keeps that run going with clean 8ft and 7ft waves and offshore winds. This stretch from Wednesday to Friday is the real deal.

After that, we drop off. Saturday the 18th is small and clean but only around 4ft, and Sunday the 19th picks up a bit to 5ft and 6ft, but with a very long period (18 seconds) from the SSW. That’s a groundswell that will be lining up, but it might be a bit too straight for a beach break – the point is better. The wind is cross-off, so it’s clean, but the energy is moderate (1739 and 3893). It’s a decent option, but not a standout.

The following week is a mixed bag. Monday the 22nd looks promising with 6ft and 7ft and clean conditions, but then Thursday the 23rd brings another massive pulse of 12ft swell from the SSW, with 16-second periods. The wave energy is huge (over 6000), and it’s clean, but it’s too big for this break again. After that, it’s a slow fade into smaller, cross-shore, lumpy stuff through to the end of the period.

So, the takeaway? The absolute best window is Wednesday the 15th through Friday the 17th. Those are the clean, glassy, manageable days. The long-range stuff on the 19th and 22nd is promising but less certain. Don’t get too excited about the big swells – they’re just too much for Knights.

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.
