G’day, Rusty here. Let’s break down the surf at Cactus. We’ve got a solid run of clean, solid swell coming up, but it’s not for everyone. The water temp is about normal for this time of year.
The first real action kicks off on Sunday the 5th of July, and it’s a cracker for experienced surfers only. We’re looking at a solid 6ft SW groundswell with a 17-second period—that’s a heap of power (2191). The wind is a clean offshore from the ENE, 12 mph, keeping those waves lined up and glassy. This is top-tier, heavy reef surf. Afternoon holds at 6ft SW, still offshore, still clean. If you’ve got the skills, this is your session.
Monday the 6th eases back to 4ft SW, clean enough, but the wind is cross-offshore, so not as perfect. Energy drops to 536.
Tuesday the 7th sees a return to cleaner conditions with a light ENE offshore, 4ft SW and a nicer 15-second period. Good shape, good energy (525). Afternoon is cross-off but still clean.
Wednesday the 8th is another standout—6ft SW, 17-second groundswell, strong energy (1710), and super clean with a light breeze. This is excellent, powerful reef surf for experienced surfers. Crowds are sometimes, so expect company.
Thursday the 9th drops to 4ft SW, clean in the morning, but by the afternoon the wind swings cross-onshore with rain showers. Gets messy.
Friday the 10th is marginal. 4ft SW, cross-shore and cross-onshore, creating chop.
Saturday the 11th is a write-off. Strong onshore winds, 19 to 22 mph, lumpy and poor.
Sunday the 12th sees another pulse of 7ft SW but it’s still cross-onshore and messy. Lots of energy (1703) but the wind spoils it.
Monday the 13th is mixed. Morning is ok with light cross-shore wind and 5ft SW, but the afternoon ramps up to 8ft SW with a 20-second period—huge, long-period groundswell (4600). That’s a monster wave but the cross-onshore wind adds some chop. Only for experts, and it’s a bit rough.
Tuesday the 14th through to Wednesday the 15th sees solid swell but poor wind continues.
Thursday the 16th of July is a nice little surprise. Morning is glassy, 4ft SW, 14-second period, and clean as a whistle (623). That’s a lovely session for intermediates. Best of the second week.
Friday the 17th drops right off. Only 2ft SW, cross-shore and messy. Poor surf.
Saturday the 18th brings 7ft SW but strong cross-onshore winds, making it choppy.
Sunday the 19th sees the biggest swell of the whole forecast—8ft SW, 17-second period, and a massive 6647 energy reading. That’s a monster. The wind is only a light cross-shore, so it’s cleaner than it could be, but this is still only for experts. Could be a standout for the hardcore crew if the wind stays light, but it’s a long way out.
Monday the 20th drops to 7ft SW, still cross-onshore and a bit lumpy.
So, the standout is easily Sunday the 5th and Wednesday the 8th for clean, powerful, long-period SW groundswell with offshore wind. For the second week, Thursday the 16th is the one to aim for if you want clean, manageable waves. Big stuff on the 19th is one for the experienced, but keep an eye on the wind.
Rusty out.

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.
