Table - best surf conditions forecast for Cobden Breakwater over the next 16 days.
Alright, mates, Rusty here. Let’s break down what’s coming for Cobden Breakwater over these next sixteen days.
The surf kicks off proper on Saturday, July 11th. Water temp is 56°F, pretty average for the season.
The real standout is Saturday the 11th and Sunday the 12th. Saturday afternoon is dead flat calm, glassy, with a clean 4ft WSW swell at a very long 16 seconds. The wave energy’s moderate. Sunday morning holds 4ft with a light offshore east wind, still at 15 seconds. This is prime, clean, lined-up surf.
Monday the 13th is smaller – 2ft in the morning – with a cross-off breeze. Afternoon picks up to 4ft but with a short 7-second period and stronger wind, so it’s a bit messy.
Tuesday the 14th swings to a WNW swell. Morning is 5ft clean; afternoon builds to 6ft but with a moderate onshore wind. Strong energy but choppy.
Wednesday the 15th is for experts only: morning hits 12ft at 15 seconds with cross wind and massive 5515 energy – too big for most. Afternoon still 10ft and onshore.
Thursday the 16th is a gem for skilled surfers: 8ft in the morning with light cross-off wind, clean. Afternoon goes glassy at 7ft.
Friday the 17th stays solid at 6ft in the morning, glassy, then 5ft in the afternoon, also glassy. Great shape.
Saturday the 18th is another cracker: 8ft WSW in the morning with a gentle cross-off, then 7ft in the afternoon glassy. Crowds could be around.
Sunday the 19th offers 5ft in the morning, glassy, then 5ft dropping in the afternoon. Clean all day.
Monday the 20th through Wednesday the 22nd hold at 4-4ft with offshore or glassy winds. Fun, smaller waves.
Thursday the 23rd and Friday the 24th drop to 3-3ft. Still rideable. Saturday the 25th has a long-period spike at 3-4ft with a 17-19 second swell, glassy in the afternoon – a potential sleeper.
Sunday the 26th is back to 3ft in clean conditions.
The best windows are the early weekend (11-12) for pure quality, then Thursday the 16th through Sunday the 19th for consistent, well-shaped surf. For the big stuff, Wednesday the 15th is only for the brave.
Rusty signing off.
