Auckland, NZ Daily Water Report — October 9, 2026

Auckland Harbour is a clear go for most scored water time today, with boating the standout at 8.7/10 and a notably gentle sea state doing much of the heavy lifting. This is a harbour day for making use of calm water rather than chasing drama: waves sit around 0.16 m, with only 0.12 m of short-period swell, while the ENE wind is generally light at 2–7.6 knots. The best all-round window is early, from dawn through mid-morning, when the air is cooler but the harbour should be at its least worked-up before gusts build. The forecast’s strongest gusts reach about 20 knots around 13:00, so small craft, paddlers and anyone planning a long exposed crossing should treat midday as the trade-off period. The representative wind may be only 7 knots, but gust spread matters more than the average when you are in a kayak or handling a light boat. Kayaking rates 7.6/10, diving 7.8/10 and sailing 7/10. For divers, the low waves and light wind are encouraging, but water temperature is a cool 14.9°C, slightly below the seasonal average, so thermal preparation is not optional. The reported 46.2 km atmospheric visibility is excellent for getting around, but it says nothing about underwater visibility. No rain is indicated, pressure is stable near 1026 hPa, and cloud cover is sparse, making this a pleasant day above the surface as well. Fishing improves sharply to 7.2/10 after several weaker recent scores. The 11:42–13:42 solunar major period is the prime timing cue, though it overlaps the gustiest part of the day; the 06:12–07:12 minor period offers a calmer alternative around first light. Tide data are unavailable, so do not assume a tide-driven advantage or current pattern. Wildlife scores 7.7/10, with the 18:12–19:12 minor period lining up neatly with the evening light. Compared with the recent record, boating is just shy of yesterday’s 8.8 but remains among the week’s best, while fishing is materially stronger than yesterday’s 6.2. The next few days look wetter and a little windier, with wave heights rising to 0.4 m Saturday and Sunday before a very calm-looking Tuesday and Wednesday. Best bet: launch early, enjoy the glassy harbour while it lasts, and be back with the kettle on before the lunchtime gusts get ideas.
