The Lowdown
Alright folks, Rusty here. Let's have a look at what’s cooking at Marley over the next couple of weeks.
It’s a bit of a mixed bag on the whole. We’ve got some solid swell pulses coming through, but the wind is going to be our biggest challenge. For the first few days, it's pretty ordinary – the swell is tiny and the wind is messy, so you’re better off doing something else. Things start to look up from Friday the 4th when a light offshore breeze meets a clean 4-foot south swell, but it's still a bit small for the advanced lineup here. The real standout, the one you want to circle on the calendar, is Friday the 11th. For the morning session, Marley is looking absolutely perfect. We’ve got glassy conditions, zero wind, and a groundswell from the south at 5 ft with a 12-second period. Combined swell energy is a solid 548 – that’s proper juice. The water temp is hanging around 64°, which is about average for this time of year.
Early on the 4th, with that light offshore and chest-shoulder high south swell, it’ll be worth a look. Crowds are possible here, so get in early. The southeast swell direction is spot on for Marley. By Sunday the 6th morning, the swell bumps up a bit to 4 ft, but it’s got a cross wind on it, which makes it less appealing. Monday the 7th morning cleans up again with another light offshore and a 3 ft south-southeast swell. It’s not huge, but that 9-second period should give you something to play with. The combined energy is 260.
After the 11th, the weekend of the 12th and 13th sees things drop off. The swell gets small and inconsistent, though the 13th morning has a super long-period 1 ft swell at 18 seconds – that’s all energy and no height, tricky. The following week is a write-off for good quality until the 18th. On Friday the 18th, there’s a big pulse of energy coming through – 8 ft south swell and a 19 mph offshore wind. That’s advanced territory and the energy reading is massive at 1059, but it’s a long-range call, so don’t book your flights just yet. The afternoon session on the 18th has a cleaner 8 ft south swell and fresh offshore wind – again, for experts only.
Rusty.

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