Table - best surf conditions forecast for Cactus over the next 16 days.


The Lowdown

Right, let’s have a look at what’s on offer for Cactus. It’s a reef break, exposed to the SW, and it’s fairly consistent, so it’s got potential. The water temp is sitting at 61°, which is about average for this time of year, so nothing weird there.

We’re kicking off Friday the 17th. The swell is a clean 4ft from the SW, with a solid 16-second period. That’s proper groundswell, and it’s got some decent energy behind it (619). The wind is a cross-offshore breeze, which will keep things tidy. The score is low, but the conditions are clean. It’s a bit of a slow start, but it’s rideable. The combined energy is moderate (619).

Through the weekend, we see the swell drops off. Saturday morning is 3ft, and the energy is down to 215. The wind holds as a cross-off, so it’s clean, but the size is small. Sunday is even smaller in the morning, 1ft, but with a long period again (19 seconds). The afternoon gets a bit of a cross-chop, so it’s not great. The whole weekend is marginal, and the scores reflect that.

The first real standout comes on Tuesday the 21st. The morning session has a 4ft SW swell with a 13-second period. The combined energy is a solid 560. The wind is a light cross-off from the north, and the forecast says “expect very good surf conditions.” It’s a bit of a hidden gem here. The sets will have some power, and the surface will be clean. This is the best early call.

Then we get a bit of a lull. Wednesday the 22nd morning is glassy, with a 3ft swell, but it’s a short period. The afternoon turns choppy. Thursday the 23rd morning sees a jump in size to 6ft, with a 14-second period. The energy is up to 1220, which is strong. But the wind is a cross-shore, and it’s a bit chop. This is solid for intermediate to experienced surfers, but the wind is a letdown. The afternoon is similar, 5ft and 1009 energy.

The absolute best window is Friday the 24th. The morning has a 4ft SW swell, 14-second period, and a clean offshore wind from the NE. The energy is 736. The forecast says “expect very good surf conditions.” This is the standout day. The swell is a good size, the wind is perfect, and the reef will handle the long period well. It’s the day to be out.

After that, the surf quality drops. The rest of the month and into August is mostly poor, with strong onshore winds and choppy conditions. There’s a small window on the 27th morning with a glassy 2ft, but it’s tiny. The 28th gets a 5ft swell but ruined by a strong cross-onshore. The first of August has a clean 4ft, but it’s still marginal.

Overall, the best bet is Friday the 24th. The Tuesday the 21st morning is also a good option. The rest of the 16 days is mostly a write-off, with a long gap of poor surf from the 25th onwards. The reef at Cactus can handle the groundswell, but the wind is the enemy most of the time.

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.
