The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for this stretch.

We’re looking at a solid run of swell, but it’s not all clean sailing. We’ve got a window of messy, blown-out conditions to get through first, but the real standout is a proper groundswell event that sets up beautifully for the experienced crew. The water temp is sitting about average for this time of year, nothing wild there.

The first few days are a bit of a write-off. Saturday the 25th and Sunday the 26th bring some size – around 8ft and 6ft from the SSW – but the wind is cross or cross-on, so it’s choppy and messy. It’s surfable if you’re desperate, but you’re battling ripples and a bit of a bump. Monday the 27th cleans up a little as the wind shifts offshore, but the swell drops to 5ft and the energy is moderate (507). The wind picks up strong on the afternoon, so it’s not the best call.

Tuesday the 28th is a no-go. The swell jumps back up to 10ft from the SW, but a strong cross-on wind makes it a total mess. The combined energy is huge (6207), but it’s just a washing machine. Wednesday the 29th sees even bigger swell – 12ft from the SSW with a very long period of 15 seconds – and the wind turns onshore. The energy is enormous (5691), but it’s way too big for this spot, wind is on it, and it’s really only for the madmen.

Now, the standout. Thursday the 30th. The wind drops right out to glassy conditions. The swell is 7ft from the SSW, with a period of 13 seconds, giving it a solid groundswell feel. The energy is strong (1378). This is the pick of the early run. It’s clean, it’s got power, and it’s a great window for experienced surfers. The morning is the best call, with the afternoon still glassy but a touch smaller. This is a gem.

The rest of the week into early August is a mixed bag. Friday the 31st is back to a cross-on breeze, though the swell holds. Saturday the 1st of August brings a clean offshore breeze in the morning (NNW at 3 mph), with 7ft SSW swell and a very long 17-second period. The energy is strong (2571). This is promising, but it’s a week away, so keep an eye on it.

Now, the real big one. Sunday the 2nd of August. Offshore wind (NNE at 3 mph), glassy conditions, and a massive 8ft SSW groundswell with an incredibly long 18-second period. The energy is off the charts (5511). This is exceptional, expert-level surf. The long period means it’ll be powerful and clean, but it’s going to be fast and straight at the beach, so it’s best for those who know what they’re doing. Monday the 3rd and Tuesday the 4th keep the offshore flow going, with 8ft to 7ft swell, but the period drops to 14-10 seconds. Still good, but not as epic as Sunday.

After that, the swell backs off through the second week. Wednesday the 5th and Thursday the 6th have cleaner conditions but smaller swell (5ft to 5ft) with a long period, so it’s more of a longboard or fun-grovel scenario. Friday the 7th gets blown out by strong winds. Saturday the 8th is small and weak. The last call on Sunday the 9th is a ghostly 2ft swell with a 23-second period – that’s pure, super-long-period groundswell but it’s tiny. It’ll be clean with offshore wind, but you’ll be waiting for sets.

Bottom line: Thursday the 30th of July is the first true standout – glassy, solid, clean. Sunday the 2nd of August is the big one for the experts. Everything else is a case of picking the right tide and wind window. Crowds at Knights can be likely, especially on those clean days, 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.
