The Lowdown

G'day, Rusty here, checkin' in from the Rosa region. Alright, let's be straight with you – the next week and a half is a bit of a mixed bag, but there's a couple of real gems hiding in the back half that'll have you grinning. The first few days are looking pretty average with onshore and cross-shore winds messing up the shape, but the end of the run is shaping up to be something special.

Starting off, Wednesday the 15th and Thursday the 16th are a write-off. We've got a moderate breeze from the north cross-shore, all junking up a 5ft to 6ft swell from the ESE. The energy's moderate (554) but the wind's just too messy.

Friday the 17th and Saturday the 18th aren't much better. Swell bumps up to 7ft from the NE, but it's still cross-shore and cross-onshore, making for a choppy, unrideable mess. This is a bit too big for beginners anyway, and with the wind, it's a pass.

Now, Sunday the 19th – finally a window. The morning sees a light 6 mph SW wind going cross-offshore, cleaning up that 6ft ENE swell. The energy is solid (510) and the period is 8 seconds. This is the first real standout. It's an intermediate-level wave, not too big, and the wind is magic. Expect some clean, fun lines. The afternoon gets a bit trickier with a light cross-on, but the morning is the pick.

Monday the 20th and Tuesday the 21st are a return to frustrating cross-shore winds, killing the 5ft swell. There's a glimmer of hope on Tuesday morning with a light SW cross-off again, creating clean 5ft waves, but it's a short window.

Wednesday the 22nd through Friday the 24th has some potential. On Wednesday afternoon, a light 6 mph SSW cross-off wind makes for clean 3ft waves. Thursday the 23rd is a mixed bag – the morning has a 4ft S swell with a 10-second period, but the wind is messy. The real highlight is Friday the 24th morning. A light NNW cross-off, 4ft from the ENE at 8 seconds – clean and ridable. That's a solid pick for a quieter session.

Hold onto your board for the end of the second week. Saturday the 25th afternoon sees a 3ft SSE swell with a very long 14-second period, coming in clean with a moderate cross-off. The energy is moderate (528). That's a groundswell – it'll be a bit more powerful and have longer lulls.

The absolute standout of the entire outlook is Sunday the 26th. We've got a 3ft to 4ft swell from the south, with a period of 12 to 11 seconds. The wind is light, 3 mph from the WSW and then SW, going cross-off both sessions. This is clean, glassy conditions. The energy is strong (579 and 644). This is your call to action. The longer period means it'll hold shape well, but it might break a bit straight at a beach break, so a point or reef would be your best mate. It's a moderate size, perfect for intermediates.

Monday the 27th through Tuesday the 28th sees the wind swing back onshore, ruining the 3ft to 6ft S and NE swells. The final standout is Wednesday the 30th morning. A 8ft NE swell with a 8-second period, glassy, clean conditions with a light SSW cross-off. That's a big wave, over 8 feet, so experts only. The energy is strong (808). This is a big, powerful day for the crew who can handle it.

So, the best on offer is without a doubt Sunday the 26th – clean, mid-sized, groundswell, and glassy winds. The second best is the big Sunday the 30th for the experts. The rest of the time, you'll be scratching around for a window. The water's about average for the time of year.

Rusty.

Information about the Rosa Surf forecast

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