The Lowdown
Alright, let’s be straight with you. The next couple of weeks are looking pretty grim for a surf at Marlin. The swell is there, don’t get me wrong, but the wind is just constantly onshore or cross-onshore, and it’s messing up what little shape there is. You’re looking at a whole lot of lumpy, choppy lines, nothing you’d want to paddle out for unless you’re desperate.
Right off the bat, Tuesday the 15th kicks off with a weak 4ft ESE swell at 8 seconds, and the light morning breeze turns into a bumpy afternoon. It’s poor, plain and simple. Wednesday the 16th is more of the same – 4ft, short period, cross-onshore wind. We’re just not getting any quality here. This continues right through the first week, with the swell staying small and the wind staying messy. The energy is weak to moderate, mostly in the 160 to 400 range, but it just doesn’t matter when the surface is blown out.
There is a slight glimmer around Thursday the 17th, when the period jumps to 11 seconds, but the swell is still that puny 4ft, and the cross-onshore wind ruins any chance of clean faces. It’s just not enough to get excited about.
Honestly, the whole run is a write-off for surfing. We go from Tuesday the 15th all the way through to the end of the month with every single report saying “poor surf conditions.” It’s a solid two-week blank.
The swell does push up a bit later on – around the 24th and 25th you get 5ft to 6ft, but the period drops back down to 8 seconds, and the east wind is still on it. It’s just a wall of mush and chop. There’s a bit more energy late on the 23rd with a longer 12-second period, but again, the onshore wind just chops it all up. For a beginner, anything over 5ft starts to get intimidating, and with that crumbly, onshore wind, this isn’t the place to be learning.
This looks way more interesting for the kiteboarders than for anyone with a paddle. If the wind stays like this, you’re better off leaving the board in the car. The water is a warm 79°, which is about normal for this time of year, so at least you won’t be cold while you’re getting blown around.
We’ve got a long stretch of nothing on offer. No standouts, no hidden gems. Just a flat, choppy, windblown couple of weeks. Forecasts can change, but right now, I wouldn’t be holding my breath.
Stay patient, Rusty.

Information about the Marlin Surf forecast
The above surf forecast table for Marlin provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Marlin can be found by selecting the local surf guide option on the grey menu. Our Marlin 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 (Marlin) 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 Marlin 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.
