The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Ram5 over the next couple of weeks. We’ve got a classic point break (Ram5) that needs a good south-west swell and some light winds to really fire. The water temp is sitting about average for this time of year, nothing freaky there.
The next sixteen days look like a bit of a mixed bag, with a few windows of clean surf but plenty of average to poor conditions in between. The early part of the run, starting this Saturday morning (12th September), offers the first real chance. We’ve got a clean 3ft SW groundswell with a solid 12-second period and a light cross-off breeze. The combined wave energy is moderate (312), and it’s glassy. This is a genuine standout for early morning sessions – the point should be peeling nicely with that long period, offering proper shape. It's an advanced break, and it's consistent, so expect some crew out there, but the quality will be worth it.
That Saturday afternoon sees the wind swing onshore and the quality drop off quickly. The next real highlight comes on Tuesday morning (15th September). The swell has backed off slightly to 3ft from the WSW, but the period is still a very long 14 seconds, and the wind is dead calm – glassy. The energy is moderate (416). That combination of a proper groundswell and zero wind will have the point looking like a mirror. This is the best on offer for the first week.
Wednesday morning (16th) is another glassy morning with a smaller 3ft SW swell (13s period). It’s clean but small, a good option if you're keen for a paddle. After that, the following days (17th to 20th September) are a write-off – poor conditions dominate with onshore or strong cross-shore winds and weak, messy swell. There is a three to four day gap of poor surf here.
The next real standout is further out, on Monday morning (21st September). The swell jumps up to a more solid 5ft from the SW, with a short period of 8 seconds. The wind is light and cross-off, keeping it clean. Even though the period is short, the size and clean conditions will create punchy waves at the point, and the energy is moderate (356). Being 5ft, it's a bit too much for beginners, but for the advanced crew, this is the biggest and best-looking session of the whole run, but it's a long-range call so keep an eye on it.
After that, Tuesday (22nd) onward is a real struggle again with mostly poor conditions and small, weak swell. The final mention is Saturday morning (26th September). It’s a glassy morning with a 3ft WSW groundswell (11s period) and combined energy of 235. Clean, small, and good for a longboard cruise, but not a standout.
Overall, the real winners are the Tuesday (15th) for the glassy, long-period groundswell, and the Monday (21st) for the biggest, punchiest swell of the period. Get on them early.

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.
