The Lowdown
Imperial Units
Alright, to be straight with you, the next week is going to test your love for the sport. We’re in a pretty flat spell right out of the gate. For the first few days, you’ll be looking at weak, choppy surf with winds swinging from NNW to SSW. The wave energy is low, mooching around in the hundreds. The water is sitting at a balmy 64° which is about 4° warmer than normal, so you could almost call it bathwater, but there’s just nothing to ride.
Things start to hint at life on Friday the 21st. That morning we get a glass-off. The wind goes totally still and the ocean gets that oily, clean look. We’re looking at a 3ft swell from the WSW, but it’s a short period wind swell at 9 seconds, so the power is down (energy around 273). It’s surfable, but it’s not going to bowl you over. By Saturday the 22nd, we’re back to dribble with only 2ft on offer.
Now, here’s where it gets interesting. For a long-range standout, keep your eyes on Saturday the 29th of August. That morning, the stars align. We’ve got clean, glassy conditions and a solid 7ft groundswell from the WSW with a period of 14 seconds (energy surging to 1835). That’s proper power. For a point break like Ram5, this is the call of the week. Just a heads up though – at 7ft, this one is going to push the limits; it’s really one for the experienced crew. The afternoon sees a little cross-shore kick in, so the morning session is your golden ticket.
After that pulse, it backs off through the end of the month and into September. There’s another pulse of long-period, 19-second swell hitting around Wednesday the 2nd of September, but it's got a moderate cross-shore wind messing things up and the size is pretty inconsistent, so it’s more of a watch-and-see.
So to sum it up: suffer through the first week, there’s really nothing going on until Friday the 21st for a small clean session. But the absolute standout, the day to circle, is the morning of Saturday the 29th of August. Get on it 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.
