The Lowdown

Alright, this is Rusty, and I’m looking at what’s on the menu for Cactus.

Right off the bat, we’ve got a solid run of surf coming in. The swell’s showing up from the southwest, and that’s exactly what this reef needs. The first few days are a bit of a mixed bag, but we’re looking at some real standouts if you pick your windows right.

The real action kicks off on Friday morning, July 24th. We’ve got a solid 6ft SW swell running with a long 15-second period – that’s proper groundswell, lots of energy (1314). The wind is a light cross-offshore from the southeast, keeping it clean. This is excellent condition for experienced surfers. It’s a touch on the bigger side, so not for the groms, but for anyone who’s been around, this is a juicy window.

Saturday morning, July 25th, is a real treat. The swell drops to 4ft, but the wind goes glassy. Dead calm. That’s a rare gift. The swell direction is still perfect from the southwest, and the period is a solid 13 seconds. It’s a smaller morning, but with zero wind, the waves will be silky smooth. This is a standout for pure quality.

We’ve got a bit of a lull mid-week, with some choppy afternoons and onshore winds, but don’t write it off. The following week holds some gems. Thursday morning, July 30th, is another cracker – offshore wind from the east, 5ft swell, and clean conditions. The energy is strong (953). Then, on Friday afternoon, July 31st, we get a monster of a long period swell at 19 seconds, 4ft, with a clean cross-offshore breeze. That’s a very long period groundswell, and it’ll be peeling down the reef. That’s a standout for the pure energy and shape.

Heading into August, we’ve got bigger pulses. Saturday afternoon, August 1st, is for the experienced crew – 7ft of SW swell with an 18-second period, could be a bit much for the average punter. The next big one is Monday morning, August 3rd, with 7ft and a 16-second period, with a light offshore wind. That’s a serious, powerful swell. The water temperature is about average for this time of year, so no wetsuit surprises.

The crowds here can be a factor sometimes, so keep that in mind, especially on the glassy mornings.

The second week thins out a bit. There’s a good window on Thursday morning, August 6th, with a 5ft SW swell and clean conditions, but after that, the wind turns onshore and the swell fades. By the second weekend, it’s a washout, with onshore winds and small, poor surf.

So, to sum it up: the best of the best is Saturday morning, July 25th, for the glassy, clean conditions, and Friday afternoon, July 31st, for the spectacular long-period groundswell. Get on it.

Rusty.

Information about the Cactus Surf forecast

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