Sydney Harbour, NSW Daily Water Report — September 1, 2026

Today in Sydney Harbour, diving takes the crown with a stellar 9.2/10 suitability score. If you're looking to explore the underwater world, now's your chance. With wind at a gentle 5 knots from the ENE and waves peaking at a manageable 0.84 meters, conditions are near perfect for a dive. The water temperature is a steady 17.5°C, making it comfortable for extended underwater exploration. For surfers and boaters, it's a pretty good day as well, with both scoring 7.9/10. The moderate swell coming from 159 degrees at 0.72 meters offers decent surfing conditions, particularly during the solunar major period from 14:12 to 16:12. Boaters will appreciate the lack of rain and clear skies, though the occasional gust up to 14 knots might keep you on your toes. Fishing is looking a touch better than recent days, scoring a respectable 7.7/10. The solunar periods are your best bet for casting a line, especially the major one in the afternoon. Though the tides are a mystery today, the steady barometric pressure should keep fish behavior predictable. Kayakers and sailors might find today less thrilling, with scores of 6.6/10 and 6.7/10 respectively. The wind is fairly light, which is a plus for kayakers, but the moderate current might be a challenge. Sailors might find the conditions a bit too placid, though the afternoon could bring a slight uptick in wind activity. Looking ahead, expect similar conditions with slight variations in temperature and wind over the next few days. The calmest waters are predicted near 22:00 tonight, so if you’re planning a late venture, that's your window. If you're diving today, relish it—conditions like this don't come around every day.
