The Lowdown
Alright, listen up you salty dogs. Rusty here, and I’m not gonna sugarcoat it. The next 16 days for Marlin look like a real test of patience. The wind is going to be your enemy more often than not, and we’re scraping the bottom of the barrel for a decent session.
Water temp is about 79°, which is normal for this time of year.
We kick off with a real dud. Tuesday the 4th and Wednesday the 5th are a total loss – onshore winds and poor surf. Thursday the 6th morning gives us a glimmer with a "marginal" tag, but it’s just 4ft from the ESE at 8 seconds with a light onshore breeze. The energy is weak (231). It’s a longboard or a foamie kind of day.
The weekend? Forget it. Friday the 7th through Sunday the 9th is all rubbish.
The one standout, and I mean the only one, is Thursday the 13th. The swell jumps up to 7ft from the SSE. That’s some size, but the period is a short, choppy 8 seconds, so it’s not a clean, rolling swell. The energy is in the moderate-to-strong range (624). The wind is a gentle cross-onshore, so it’ll be a bit bumpy, but it’s your best shot at a wave with some push. At 7ft with a short period, it’ll be a bit of a washing machine, so it’s for the experienced crew only. And you can bet the crowds will be there.
Friday the 14th drops in size to 4ft, but the period jumps to 12 seconds, giving you a much better shaped wave from the S. The wind goes light onshore, which is a shame. The energy is moderate (491). It’s a better quality wave, but it’s much smaller.
The last week from the 15th onward just fades out. Tiny swells, persistent onshore winds. A few slots on the 15th afternoon and 16th get a "marginal" call, but the swell is weak and the period is all over the shop.
So, what’s the plan? If you’re itching to get wet, Thursday the 13th is the only day with any real size. It’s not pretty, but it’s the biggest wave on the menu. For the rest, it’s a waiting game. Forecasts can change, so don’t give up hope, but right now, it’s a grim outlook.
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.
