The Lowdown
Alright, let’s break it down, mate.
For the next 16 days at Cattle Grid, it’s mostly a flat and quiet stretch. From now until the morning of Sunday September 6th, you’re looking at a whole lot of nothing – over a week of tiny, weak surf or total flatness. The water temp is about 58°F, which is a touch warmer than usual for this time of year, so your wetsuit can be a little thinner.
Friday morning August 28th gives us a brief moment. Swell is 4ft from the ESE with a 9-second period, light cross-offshore wind from the SSW, and moderate energy (214). It’s clean and rideable for intermediates on the reef. By the afternoon, the wind turns onshore and it’s game over.
Saturday August 29th is tiny – 2ft down to 1ft – but glassy. Surfable on a longboard, but nothing to get excited about. Sunday through the following Friday is all tiny or flat. Don’t even think about it.
Then comes Sunday September 6th. The morning delivers a solid 10ft swell from the north with a short 8-second period and strong energy (1024). Wind is cross-offshore from the WSW at about 12 mph. That’s a lot of water moving fast – powerful, dumpy, and strictly for experienced surfers only. Beginners, stay on the beach. That morning window is the real standout of the whole outlook – a proper expert session.
The afternoon drops to 5ft and gets a bit messier with stronger cross-off wind.
Monday September 7th is back to small and clean but not worth the paddle out.
Then Tuesday September 8th, the afternoon brings a 3ft swell from the SE with a very long period of 15 seconds. That’s groundswell, and with glassy conditions and light air, it’ll be clean. The energy is moderate at 361. On a reef, that long-period swell can shape up nicely, but at 3ft it’s a fun, mellow wave. Not a standout, but a nice little bonus after the flat spell.
After that, it’s back to small, choppy dribble for the rest of the forecast.
Best on offer: Sunday morning September 6th – big, powerful, and for experts only. Tuesday afternoon September 8th is a clean, small groundswell session for intermediates.

Information about the Cattle Grid Surf forecast
The above surf forecast table for Cattle Grid provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cattle Grid can be found by selecting the local surf guide option on the grey menu. Our Cattle Grid 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 (Cattle Grid) 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 Cattle Grid 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.
