The Lowdown

Alright, Rusty here. Let's check out the lineup.

We're looking at a 16-day forecast, and the first few days are a bit of a mixed bag. The real standout is clearly later in the period, but there are some solid windows to work with. The water temp is sitting at 58°, which is pretty much normal for this time of year, nothing unusual.

The first real action kicks off on Saturday, August 1st. The morning session is looking prime at Knights. We've got a clean 6ft SSW groundswell rolling in with a very long 17-second period, the energy is solid (1905). That's a proper groundswell. The wind is light and offshore from the north, so it's going to be clean, lined up, and perfect for the more experienced crew. This is advanced territory, so leave the soft tops at home. The afternoon holds up too, with a touch more size at 7ft and the wind shifting to a cross-off, still clean. Crowds are likely here, so get in early.

Sunday morning, August 2nd, is still rideable but the wind is picking up—a fresh 19 mph cross-off from the NNW, which will put a bit of texture on it. The 6ft swell is still there, but the quality drops. By Sunday afternoon, the wind swings onshore and the rain starts, so that's a write-off.

Monday, August 3rd, is a no-go. The swell jumps to 10ft, but it's a short-period, onshore mess. The energy is huge (3285 to 6103) but it's all wind-chop and poor quality. Forget it.

Tuesday the 4th is still messy with onshore winds, though the swell drops. Not worth the paddle.

Wednesday, August 5th, is the real gem of the first week. The morning is cloudy with a tiny 3 mph offshore breeze from the north, and a clean 4ft SSW groundswell (period 15s). The energy is still moderate (1437). It's clean and perfect for the advanced crew. But the afternoon... that's the magic window. The wind goes completely glassy, the swell is 4ft, and it's a repeat of the same long-period groundswell. It's going to be silky smooth. This is the best session of the first week.

Thursday the 6th is small, with a 3ft SSW swell, but the morning is glassy. It's clean for a small wave longboard, but nothing to get too excited about. The crowd may be thin at that size.

Friday, August 7th, brings a return of size. The afternoon is a standout with a clean 7ft SSW swell, a 17-second period, and light offshore winds from the north. The energy is pumping at 3544. This is a proper session for the advanced crew.

The second week starts to get a bit wild. The swell really kicks in from Monday, August 10th, with a 10ft WSW swell, but the wind is onshore. It's a big, messy, dangerous mess. Not for paddling, but that kind of power and short period could be a kite session if you're into that sort of thing.

Wednesday, August 12th, is the big one to circle. The morning is a total anomaly. The wind is dead calm, glassy, and the swell is a massive 12ft from the SSW with an 18-second period. The energy is astronomical at 7392. This is a major, major groundswell. The problem is, it's too big for this break. It's a serious, advanced-only, potentially dangerous day. The setup is a beach and reef, so with that kind of period, the waves will be bowling, but it's only for the absolute best. If you're not an expert, stay on the sand and watch the show.

The rest of the week from the 13th to the 15th is a write-off with onshore winds and messy conditions.

Sunday, August 16th, finishes the window nicely. The morning has a clean 4ft SSW swell with a light offshore from the NE, and the afternoon goes glassy with a 4ft swell. It's a small, clean, gentle end to the forecast. Good for a cruise.

So, to sum it up: the absolute best on offer is the glassy, clean small swell on Wednesday, August 5th afternoon, and the huge, powerful, expert-only groundswell on Wednesday, August 12th morning. If you can only pick one session, go for the 5th for reliability and perfection, or the 12th if you're a true charger and want to test your limits.

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.
