The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the Knights stretch, a beach and reef setup that takes exposure from the SSE and really wants the swell out of the SSE to line up.

Kicking things off, we’ve got some swell in the water right from Thursday the 30th of July, but don’t get too keen just yet. That first day is a bit marginal with a cross-on wind and a combined energy of 1872, meaning there’s moderate wave energy around, but the wind is messy. It’s not really game on until Friday morning.

Friday the 31st is where we start to see the clean-up. A nice NE offshore breeze, 5ft of SSW swell with a 12-second period – that’s proper groundswell energy. The energy drops to 729, but the conditions are clean. It’s a solid option for the advanced crew, but it's not the standout.

Now, Saturday the 1st of August is the one to circle. We’ve got a clear sky, a firm N offshore breeze at 9 mph, and the swell bumps up to 6ft from the SSW, with a very long period of 17 seconds. The combined energy jumps to 1905 – that’s proper grunt. This is quality groundswell, and with that offshore wind, it’s going to be clean and lined up. The water temp is sitting at 58°, which is about average for this time of year. Keep in mind, this break can get crowded, so get in early. This is the best on offer in the first week.

Sunday the 2nd still has size but the wind swings NNW and gets up to 19 mph, creating a cross-off breeze. The energy stays strong at 1415, but that wind strength will make it a handful. Monday the 3rd and Tuesday the 4th are write-offs with onshore wind and messy conditions – a real low point.

Then we hit Wednesday the 5th of August. This is a sneaky one. 3ft of SSW swell but with a very long period of 19 seconds and glassy conditions in the morning with a NNW cross-off breeze. The energy figure of 1331 shows there’s still plenty of push for the size. At just 3ft, it’s not big, but that period will make it fun and clean. This is a great window for the experienced surfer who knows how to milk a long-period groundswell.

Thursday the 6th continues the good run with 5ft from the SSW, 16-second period, and a clean NE offshore breeze. Energy sits at 1633. Another top morning session.

Friday the 7th of August brings the biggest swell of the first two weeks: 8ft from the SSW, 15-second period, and a solid NE offshore at 9 mph. The energy reading hits 2625 – that’s strong. This one is for the experts only; size and power are on offer.

After that, things get a bit patchy. Saturday the 8th and Sunday the 9th stay rideable with offshore breezes, but the wind picks up. Sunday afternoon sees a massive 12ft SSW groundswell predicted with an energy reading of 5004, but the WNW wind is a cross-off at 19 mph. That much size with that much period (15s) and wind will be a beast.

Monday the 10th and Tuesday the 11th are blown out with onshore winds and huge, messy swell. Not worth paddling out. Wednesday the 12th through to Friday the 14th are mostly marred by cross and cross-on winds and dropping conditions.

If I had to call it, Saturday the 1st of August is your top pick. Clean, offshore, strong groundswell, and that very long period will link up nicely. Friday the 7th is for the big-wave hunters only. Get on it.

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.
