The Lowdown
G’day, Rusty here. Let’s cut through the noise and get straight to it. Ram5 is your only real option on the map right now, and it’s a bit of a mixed bag over the next couple of weeks. This is a proper point break, so it likes a solid SW groundswell, and that’s exactly what’s on the cards, but the wind’s going to be the main player in whether you actually get a wave or just a face full of chop.
The next few days are pretty average, to be honest. Wednesday and Thursday are looking marginal with light cross-shore breezes messing things up a touch. The swell is there, around 3ft from the SW, but the energy is only moderate and the short period is making it a bit gutless. Friday’s not much better, cleaner in the morning but the wind picks up and chops it out by lunch. This is the kind of stretch where you’re better off checking the tide charts than your wax.
Now, Saturday the 12th of September is where things start to click. We’ve got a glassy morning with a light NNE breeze, and the swell bumps up to around 3ft. The period is a pretty short 8 seconds, so it’s not going to be a world-beater, but the conditions are clean and that’s half the battle. This is your first real standout window for a proper surf, even if the wave size is still on the smaller side. The afternoon goes to crap with a cross-onshore, so get out early.
The following week is a bit of a write-off for the most part. Sunday through Tuesday are all marginal, with a persistent cross-breeze and only moderate energy. The swell stays in that 2ft to 4ft range. The period does start to stretch out a bit, hitting 17 seconds on Monday, but it’s still not enough to make up for the average conditions.
Here’s the thing to watch for: Wednesday the 16th of September. The morning is pure glass – dead calm. The swell is only around 3ft but it’s from the SW and has a decent 13-second period. The combined energy is on the weaker side, but when it’s that clean, you can make the most of it. That’s your next proper surf window after Saturday.
Then we go quiet again. Thursday and Friday are poor, with onshore wind and chopped-out waves. The energy drops right off, so it’s not worth the effort.
Saturday the 19th is another looker. Morning has a light cross breeze, swell is back up to around 4ft, and the energy is moderate. It’s not glassy but it’s workable. Sunday the 20th is the real standout of the second week. The morning is glassy again, light N wind, and the swell is a consistent 3ft. The period is a touch short at 10 seconds, but it’s clean and fun. That’s your one to circle in the diary for the following week.
After that, it’s back to the grind. Monday and Tuesday are marginal, the wind is up, and the quality fades. But don’t write it off entirely. Wednesday the 23rd of September is looking promising – a glassy morning, a 4ft SW swell with a 13-second period, and the energy is strong. That’s a nice way to finish the outlook, a proper clean window that should have some push to it.
So, two real standouts: the glassy Saturday mornings. The first one on the 12th for a clean, small-wave fun session, and then the Sunday the 20th and Wednesday the 23rd for the better, longer period swell. The rest is mostly a waiting game. The water temp is about average for this time of year, so not a wetsuit drama. Ram5 isn’t the kind of break that gets packed unless it’s firing, so you should have some room to move, but keep an eye out on the clean days. The SW swell matches the break’s optimum direction, so when the wind plays ball, it should be a proper little point wave. It’s a long range forecast, so the second week is more of a promise than a guarantee, but it’s looking like the better window.
Rusty out.

Information about the Ram5 Surf forecast
The above surf forecast table for Ram5 provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ram5 can be found by selecting the local surf guide option on the grey menu. Our Ram5 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 (Ram5) 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 Ram5 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.
