Sydney Harbour, NSW Daily Water Report — October 9, 2026

Sydney Harbour is a good water day overall, with diving and boating the standout options—but the late-afternoon gusts are the catch. Light west winds and dry, mostly clear weather make the morning notably more inviting than the numbers alone suggest, while the 1.4–1.6 m swell keeps exposed water from becoming a glassy postcard. For boaters, the 7.5/10 rating is a step up from yesterday’s 6.8, helped by the very light representative wind of 2 knots and no rain indicated. Kayaking also improves to 6.8/10 after yesterday’s 6.0, though paddlers should treat the afternoon as a different session: gusts are forecast to reach 24.3 knots around 17:00. That is plenty of reason to be off the more exposed water well before then, even if the general wind remains modest for much of the day. Diving earns the day’s highest score at 8.6/10, just shy of yesterday’s 8.8. Water temperature is near 20 C, around 1.4 C above average, and the light wind is favourable. The available atmospheric visibility is 29.46 km, but that is not an underwater-visibility reading; no direct underwater visibility measurement is supplied. The 1.62 m swell, from 137 degrees at 8.75 seconds, remains the main trade-off for any exposed entry or site. Fishing rates 7.4/10, matching the strongest score in the recent week. The most useful timing is the 10:10–12:10 solunar major period, with a second major window from 22:10 to midnight. Pressure is falling from a representative 1018 hPa, and there is no tide data available, so do not build a plan around assumed tide turns. Wildlife scores 7.2/10, also benefiting from the quieter wind period, but that score is not a guarantee of sightings. Sailing is a middling 5.7/10: enough breeze may arrive later, but the widening gust spread and swell make it less tidy than the calmer-morning activities. The sea state eases only slightly late, with the day’s calmest forecast wave height of 1.38 m near 23:00. The weekend and early next week look progressively smaller offshore, with waves around 0.6–0.9 m by Sunday and Monday, though rain chances rise. Best bet: make the most of the light, dry morning—dive, boat or fish before the 17:00 gusts decide to audition for a different forecast.
