The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up at Dongara-Port Denison over the next couple weeks. First few days are nothing special, but if you can hold out, there’s a big one waiting in the second week.
Water temp is 19°, pretty average for this time of year.
Sunday the 13th kicks things off with 2.1m SW groundswell, 15-second period, but a cross-shore SSW wind at 20 km/h keeps it messy. Marginal at best.
Monday the 14th morning looks cleaner. SE breeze at 15 km/h, cross-off, with 2.3m SW swell at 14 seconds. Solid energy (2263). Over 2m, so this is for experienced surfers. The afternoon goes south with a fresh cross-shore wind and lumpy conditions.
Tuesday the 15th morning is the pick of the first week. Offshore ESE wind at 15 km/h, 2.4m SW swell, 14 seconds, clean and powerful (2383). This is a proper session for the confident surfer.
Wednesday the 16th is smaller at 1.8m, clean but unremarkable. Thursday the 17th is a washout with onshore winds.
Friday the 18th is a mess – strong onshore winds, short period at 8 seconds, lumpy and choppy. That’s kite-surfing conditions, not for paddlers.
Saturday the 19th picks up to 2.5m, but cross winds hold it back. Sunday the 20th morning is a nice surprise – 1.9m, clean, cross-off ESE breeze at 10 km/h. Energy is 1210, small but clean.
Monday the 21st is back to lumpy cross-shore, and Tuesday the 22nd is onshore and choppy. Wednesday the 23rd afternoon shows a big energy spike to 5057 with a 1.9m SW swell at 17 seconds, but fresh cross-shore wind at 30 km/h makes it rough.
Thursday the 24th morning is better – 2.5m, clean, cross-off ESE wind at 20 km/h, energy at 3227. Good for experienced surfers.
Friday the 25th morning is another strong option. Offshore E wind at 25 km/h, 2.2m SW swell, 14 seconds, clean (1983).
Saturday the 26th is the big one. Both morning and afternoon have 4.0m SW groundswell, 18-19 second period, with energy readings of 11670 and 9210. That’s massive, very long period groundswell. Cross-off winds from the ENE in the morning, SSE in the afternoon, both at 20 km/h. Experts only – over 2.5m, this is serious power. Long period means long lulls but clean, lined-up sets at this reef.
Sunday the 27th afternoon offers a glassy surprise – 2.3m SW swell, 15 seconds, with a light northerly at 5 km/h. Glassy, smooth, and still plenty of energy at 2329.
Monday the 28th fades out with onshore wind and smaller swell. Not worth the hassle.
First week, Tuesday the 15th morning is your best early session. Second week builds nicely – Friday the 25th morning and especially Saturday the 26th are the real standouts. That Saturday is the one to aim for if you’ve got the experience.
Rusty.
