Sydney Harbour, NSW Daily Water Report — August 30, 2026

Today’s waters in Sydney Harbour are a diver's delight with a stellar diving suitability score of 9.1/10. Clear skies and calm seas make for excellent underwater exploration. Boaters will also find favorable conditions, scoring an impressive 8.4/10, thanks to gentle southeast winds averaging 4 knots and a stable barometric pressure of 1029 hPa. The waves are behaving nicely, with heights ranging from 0.8 to 1.0 meters, peaking at their calmest around midday. Surfers and kayakers should find these conditions quite manageable, with scores of 7.5/10. The swell coming from 161 degrees at 0.78 meters is consistent enough to keep things interesting without being overwhelming. Fishing enthusiasts will have to work a bit harder today, with a score of 6.8/10. The solunar tables suggest the best fishing action during the major period from 12:35 to 14:35. While the fish might be playing hard to catch, patience could yield rewards during these windows. Comparing to recent days, we see a slight improvement for divers and boaters since yesterday, while surfers and kayakers might notice a subtle drop in wave excitement. The water temperature is a touch cooler at 17°C, slightly below the seasonal average, but nothing wetsuits can't handle. Looking ahead, expect a gradual warming trend with air temperatures climbing into the mid-20s by the start of September. Winds will pick up slightly, peaking at 16.1 knots by September 5th, which could spice things up for sailors. In summary, if you've been waiting for a day to take the plunge, today is your day to dive into the blue.
