G’day, I’m Rusty. Let’s chat about what’s coming up at Dongara-Port Denison. This reef break takes a westerly swell, and the water’s sitting around 68°F, which is pretty average for this time of year—just a hair cooler than usual, nothing wild.
The action starts this Saturday afternoon, July 11, with a clean 4ft SW swell out of the southwest, period 13 seconds. The energy’s moderate (483), and a cross-off breeze keeps it tidy—rideable but nothing to shout about. Sunday morning, July 12, is where it gets real: a solid 8ft SW groundswell with a long 17-second period, energy jumping to 3233. Offshore winds from the ESE make it clean and lined-up. This one’s for experienced surfers only—over 5ft, so beginners should stay on the beach. The afternoon holds at 7ft, still clean. Monday morning, July 13, pushes up to 10ft SW, period 17 seconds—that’s serious grunt with energy at 4993. Offshore ESE winds again, glassy, but this is big; only the skilled should be out. The afternoon eases to 8ft.
Tuesday the 14th drops to 7ft SW in the morning, cross-off breeze, quality a bit so-so. The afternoon improves with lighter cross-off and 7ft—clean enough. Wednesday the 15th has a glassy afternoon—wind flat, 5ft SW, period 14 seconds—that’s a beauty for a smooth paddle.
Thursday the 16th gets messy with onshore winds, and Friday the 17th, with a risk of thunderstorms and 22 mph cross-onshore, is a no-go. Saturday the 18th brings a massive 13ft SW swell with energy over 10,000, but it’s lumpy and cross-onshore—better for the kite crew given the beach-and-reef setup.
Sunday the 19th saves the day: 10ft SW in the morning, clean with offshore ESE winds—another one for the experienced. That drops to 8ft in the afternoon, still clean. Monday the 20th offers a manageable 6ft SW, offshore wind, clean—a solid all-rounder. From there, the second week sees mostly 5ft to 7ft SW swells, clean but with occasional cross-off breezes. The standout there is Wednesday morning, July 22: 5ft SW, 14 seconds, light offshore from the ENE, glassy—smooth and fun. The 26th (Sunday) morning also serves up clean 5ft SW.
The best windows are Sunday the 12th through Monday the 13th for the big, clean SW groundswell, then Wednesday the 15th afternoon for a glassy session, and Sunday the 19th morning for another top-notch day. The break breaks fairly consistently, so the rough patches are short—just a few messy days mid-week, which is normal.
