The Lowdown
Alright, let’s get into it. The next couple of weeks are a bit of a mixed bag, to be honest. We’ve got a slow patch to start, then things are looking pretty interesting further out. Ram5 is the only game in town based on what I’m seeing, so make sure you got your quiver ready for that.
Right off the bat, the start of the window this Saturday the 15th is nothing to write home about. There’s some small swell in the water, around 4ft, but the energy is weak and it’s crossed up with a light breeze making it messy. The water’s a lot warmer than usual for this time of year, running about 64°F— that’s a pretty big deal and worth noting. It’s not really a surf day unless you’re desperate for a paddle, and even then, the tide looks iffy.
That flat, frustrating vibe carries through Sunday the 16th and into Monday the 17th. The swell drops off to around 3ft or less, and we’ve got onshore and cross-onshore winds taking the shape out of what little there is. Monday morning is a definite write-off with the chop. We’re looking at a few days of nothing, just a waiting game. The energy’s all below that moderate mark, just weak.
Tuesday the 18th is more of the same – some chest-high lumps maybe, but the rain showers and bumpy conditions aren't doing anyone any favors. The swell energy is moderate but the quality is just not there. We’re just killing time until Wednesday the 19th when things start to shift a little. The swell is small, 2ft, but that long-period SW swell is starting to show. The morning is glassy with just a light cross-shore, making it the most rideable we’ve seen so far. The energy is still weak, but there’s a pulse starting to form.
Now, Thursday the 20th morning is the first real clear standout. The wind is offshore-ish, nice and light, leaving the place clean. Swell is still only 3ft, but that’s a clean 3ft on a point break. It’s the best conditions we’ve seen all week, and the consistent nature of Ram5 means you’ll get your fair share of waves. Make the most of it, because the afternoon gets a bit ragged with the wind swinging cross.
Friday the 21st keeps the good vibes rolling with a glassy morning. The swell is holding around 3ft, but the period is shorter, around 9 seconds, so it’s a little less powerful. Still, clean conditions and a point break like this will make it super fun. After that, we drop back into the gutter for a few days. Saturday the 22nd, Sunday the 23rd, Monday the 24th, and Tuesday the 25th are small, weak, and messy. We’re talking 1ft to 3ft of dribble with poor conditions. It’s a proper drought, a few days of nothing worth suiting up for.
We start to see a pulse returning on Wednesday the 26th, but it’s still tiny. The real change comes on Thursday the 27th. The afternoon sees a jump in size and energy, with the swell climbing to 4ft and the energy finally getting strong. It’s cross-shore, but the power is starting to build. This is the calm before the storm.
Because check this out – Friday the 28th is the big one. We’re looking at a serious swell pulse hitting the coast. Morning sees 8ft of SW groundswell with a 14-second period, and the energy is massive – that’s some strong, powerful ocean right there. The wind is cross but light, so it might have some texture, but there’s a ton of water moving. This is proper, expert-level surf. If you’re not comfortable on a big, powerful point, give this a miss. This is the standout of the entire window, the one you’ve been waiting for. The energy stays strong into the afternoon as well, just a touch smaller.
Saturday the 29th backs it off slightly but is still solid, in the 6ft to 6ft range. The energy is still strong. Very doable for an advanced surfer, but it’s still a bit of a handful for anyone new to this wave. Sunday the 30th brings us back down to a more manageable 5ft with moderate energy. It’s a solid, fun size to close out the weekend.
So, to wrap it up: this week is mostly a skunk with a window of clean, small waves on Thursday and Friday morning. The real show finally arrives late next Friday, the 28th, with a big, powerful swell that will have the point lighting up. That’s a long-range call, so don’t book the time off yet, but it’s looking like the one to circle. A few days of flatness after the clean bits, then the ocean wakes up and get serious. Keep an eye on the forecasts for that last week.

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.
