The Lowdown
G’day, Rusty here. Let’s be straight with you: the next week and a half is going to test your patience. There’s almost nothing rideable on the cards until Monday the 17th, and even then, it’s a struggle. The swell’s tiny, the periods are short, and the wind just keeps messing with things. We’re looking at a solid five-day gap of flat, messy conditions before anything worth paddling out for shows up.
The first real glimmer comes in on Monday the 17th. Road K (Lakes Entrance) finally starts to see a push of south swell, but it’s weak – only around 4ft with a short 6-second period. The morning looks the better call with a moderate offshore from the NNW keeping things reasonably clean. The combined energy is still in the low range at 104. It’s surfable, but you’ll be working for every wave. Tuesday the 18th sees it drop back down to knee-high with a bit of east in the swell – not worth getting excited about.
Now, here’s the standout. You’ll want to clear your calendar for Saturday the 22nd. That afternoon we get a proper pulse of SSW swell, pushing 5ft with a 7-second period. Wind goes glassy, and the conditions are described as “glassy” – that’s the cleanest we’ll see all period. The combined energy jumps to 238, which is a solid moderate punch. It’s a sandbar, and it’s very consistent, so you won’t be sitting around waiting. Crowds are often. This is the day. It’s a bigger swell, so maybe not one for the groms, but for the rest of us, this is the pick of the bunch.
Sunday the 23rd keeps a bit of that SSW swell at 4ft, but the afternoon turns messy with a cross-onshore wind. The morning is glassy and clean though, so if you miss Saturday, Sunday morning is your backup.
Further out, we’ve got a very promising sign for Wednesday the 26th. The afternoon sees the swell start to build again, up to 5ft from the east with a 7-second period, and combined energy jumps to 332 – that’s a strong pulse. It’s a bit lumpy with light cross-shore winds, and it’s labeled as marginal. It’s more than a week away, so treat it as promising but not guaranteed.
Water temp at Road K is sitting at a touch warmer than normal – 76° – about 4° above average, which is notable but nothing crazy.
Honestly, if you want waves, Saturday the 22nd afternoon is the one. Everything else before that is a wash. After the 22nd, there’s a brief window Sunday morning, then it gets rough again. Let’s hope the models firm up for the 26th.
Rusty.

Information about the Road K Surf forecast
The above surf forecast table for Road K provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Road K can be found by selecting the local surf guide option on the grey menu. Our Road K 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 (Road K) 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 Road K 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.
Road K is 28 km (17 miles) from Mastic. If you plan a vacation in Long Island New York, look for hotels and other accommodation in Mastic. Mastic has rooms for a wide range of budgets as well as car hire and transport links.
