The Lowdown

Alright, Rusty here, let’s talk about what’s on the menu for the coming days.

Alright, it’s been a bit of a mixed bag, but we’ve got some solid windows of clean, fun surf coming through for Knights. The water temp is about average for this time of year, so you won’t need the thickest suit.

The start of the run is a bit of a washout. Monday the 27th has some waist-high swell from the SSW, but the cross-off wind is moderate, and the wave energy is only moderate (750). The quality is just marginal, and the next few days are a write-off. A massive SW groundswell builds Tuesday the 28th and Wednesday the 29th – we’re talking 10ft to 13ft with a very long period of 15 to 16 seconds. The combined energy is pumping (over 8000), but it’s too big for this spot and the wind is onshore. This is a skilled surfer’s wave only, and even then, it’s a tough ask. For a beach and reef setup, that long period could make the waves feel a bit straight and tricky.

The real standout arrives on Friday the 31st of July. The swell drops to a clean 5ft from the SSW with a 12-second period, and more importantly, the wind goes light offshore from the NNE. The water will be glassy, and the wave energy is moderate (724). This is the pick of the week for a fun, uncrowded session. The forecast is solid for this one.

We get a bit of a lull, but the next serious highlight is Saturday the 1st of August. The morning is glassy with a 3ft SSW groundswell, but it’s the afternoon that really cranks. A 5ft SSW swell with a 16-second period, light offshore winds, and excellent surf conditions. The energy is moderate (1664), but it’s clean and has some punch. That’s a top-tier session.

Sunday the 2nd gets a bit windier, and the rest of the first week is a bit average with onshore winds and choppy conditions. Keep an eye on Wednesday the 5th of August. A 6ft SSW groundswell hits with a 15-second period, and the wind is glassy in the morning. The energy is moderate (1597), and the conditions are excellent for experienced surfers. That’s a promising call, but it’s a week out, so don’t lock it in just yet.

After that, the second week gets a bit more inconsistent. The swell stays around 4ft to 6ft, but the wind is a constant cross-off, which is fine but not perfect. The session on Friday the 7th of August is worth a mention: a 4ft SSW swell with a 16-second period, light offshore wind in the morning, and glassy in the afternoon. It’s a clean, slow day.

The final few days see a shift in the wind to a stronger cross-off, and the swell stays around 5ft to 5ft. The energy is moderate to strong, but the wind is fresh, so the surface won’t be as clean. The 10th of August has a moderate cross-shore, which is a bit lumpy. Overall, the first week has the best windows, especially the Friday and Saturday.

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.
