The Lowdown
Alright, folks, Rusty here. Let’s break down what’s coming at Ram5 for the next couple of weeks.
We’re starting a little slow, but there’s a real pulse of groundswell building for the end of the month and into early September. The water is sitting at 64°F today, which is much warmer than normal for this time of year – that’s a solid 5°F above the long-term average, so you’ll be fine in a spring suit or maybe even a shorty.
We get going on Friday, August 21st. The morning has a small 3ft of SW swell at 9 seconds, but the wind is a light WNW breeze of 10 km/h blowing offshore. It’s a little marginal, but the afternoon cleans right up with glassy conditions. Swell drops to 3ft, but the combined energy is moderate at 251. It’s small, but it’ll be clean. Saturday the 22nd and Sunday the 23rd stay small – 2ft to 2ft – with glassy mornings but very ordinary wave quality. The energy drops into the double digits (93) by Sunday afternoon. Not really worth paddling out for.
Then we hit a dry spell. From Monday the 24th right through to Wednesday the 26th, the swell is tiny and the wind is cross-shore or cross-onshore. The combined energy is below 200, and the conditions are poor. Thursday the 27th sees a slight bump to 3ft with a moderate 417 energy, but it’s still not clean enough.
Now, here’s the standout. Friday, August 28th is the day to circle. We’ve got a solid 7ft of SW groundswell rolling in with a very long period of 16 seconds. The combined energy hits a strong 2322 in the morning. The wind is light cross-onshore at 10 km/h, so it’s not perfect, but this is a powerful, long-period swell at a point break that likes SW. This is advanced territory – 7ft is getting big, and with that period, it’s going to be a lot of water moving fast. Saturday the 29th still has 6ft of WSW swell at 14 seconds (energy 1110), but the wind stays light cross-onshore. It’s a great follow-up day, but the Friday is the bigger, more powerful one.
The second week starts to taper. Sunday the 30th and Monday the 31st hold 5ft to 6ft of SW swell, but the wind picks up to 15-20 km/h cross-shore, creating a bit of chop. The energy drops into the 800-900 range. By Tuesday the 1st of September, we’re back to 4ft and the conditions are poor. Wednesday the 2nd has a weird one – just 2ft but with a very long 18-second period. That’s a lot of energy (418) for a tiny wave, so it might be lined up and weird, but it’s not a recommendation.
Then, looking way out, Saturday, September 5th shows a promising pulse. 7ft of SW swell at 16 seconds, combined energy of 1895. Wind is a gentle 15 km/h cross-shore. It’s a long way off, so take it as a heads-up, but if it holds, it’s another solid day for experienced surfers at Ram5.
Overall, the best bet is the Friday the 28th of August and the Saturday the 29th. The swell is big, the period is long, and the energy is high. Get out there if you’ve got the skills. Crowds are possible at Ram5, especially on a Friday, so be ready to share the peak.
Rusty.

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.
