The Lowdown

Alright, let’s get stuck into it. It’s Rusty here, and I’ve been staring at the charts for Ram-Five for the next couple of weeks. Honestly, it’s a bit of a mixed bag, a real patience-tester, but there are a couple of windows that’ll make it worthwhile if you’re keen.

The water’s hanging in there at a very toasty 65°, which is a solid 5° warmer than usual for this time of year. That’s a big deal – you can get away with a thinner suit, no question.

For the first stretch, through the 13th and into the 14th, we’ve got some small but clean-looking swell. Thursday morning looks like the pick of this early run. We’re looking at 3ft of SW swell, but with a long 18-second period. The wind is light from the WSW, and while it’s technically cross-on, the afternoon is looking glassy. The energy is moderate. That long period means the waves will have some push to them. Good shape for a point break like Ram5, though it might be a little straight for some. The 13th afternoon is another good one with the glassy conditions and 3ft of SW swell at 17 seconds.

The 15th and 16th see the swell nudge up to 4-4ft, but the period drops into the 10-13 second range. It’s still surfable, but the conditions get a bit more cross-choppy. Mornings with light winds are your best bet, but these are becoming a bit more marginal.

Then there’s a real lull from the 17th to the 24th. There’s still swell on the charts, but it’s a lot of small, short-period wind swell mixed with onshore or cross-onshore winds. Honestly, for a few days there it’s pretty poor. We’re looking at a lot of 2-3ft stuff with 8-10 second periods, and winds picking up for a while around the 20th. The energy is still moderate, but it’s just not going to have any punch or shape. This is a real wait-it-out period. The 17th morning, August 17th, has a brief moment with glassy wind and 3ft of 14-second SW swell, which is the only real flicker of light in this stretch, but it’s low energy.

The end of the window, from August 26th, starts to show some life again. The 26th has that building SW swell, with 3ft but a cracking 18-second period. The morning wind is light from the west, and the afternoon is light cross-shore. Energy is still moderate, but you can feel a change coming.

The real standout for me is the morning of the 13th of August. It’s not big, but with that long period and the glassy conditions, it’s going to be clean and fun. The other one to circle is the 26th – that 18-second period is the real deal, a proper groundswell, and it’s worth keeping tabs on even if it’s a week and a half out.

I'd steer clear of the 18th to the 24th for surfing. It’s just too messy, with the cross-chop and low period. On the 19th and 20th, with the moderate cross-shore winds, it might look more interesting for the kite crew than for a surfer.

Alright, keep your eyes on that forecast and don’t get too down about the flat spells – it’s all about picking the windows.

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.
