Denman Island, BC Daily Water Report — October 8, 2026

Denman Island gets an emphatic go for sheltered-water plans: kayaking leads the card at 9.1/10, boating is 8.7, and diving 8.1. The sea state is almost comically restrained, with waves around 0.04 m and only a 0.04 m swell; the day’s range stays between 0 and 0.1 m. Light west wind, represented at 3 knots, should leave plenty of room for quiet paddling, careful boat handling, and low-motion dive entries. The practical sweet spot is from dawn through the late-morning low tide at 10:36 AM, when wind remains light and daylight is established. A second useful window opens around the 5:02 PM high tide and runs toward dusk at 7:19 PM, though temperatures will be falling from a daytime high near 20 C and the evening tide turns quickly toward the 11:27 PM low. Water is about 14 C, so divers should treat the flat surface as comfort, not warmth. Atmospheric visibility is forecast near 21 km, but that is not a read on underwater visibility. Fishing is a middling-but-serviceable 6.2/10, close to the recent run of 6.1–6.4. The strongest timing supplied is the late-morning solunar major period, 10:41 AM to 12:41 PM, overlapping the start of the flood after low water. The 10:41 PM–12:41 AM major period is also notable, but it comes with the day’s strongest gusts, up to 12.1 knots around 11 PM. Pressure is falling from near 1020 hPa, another reason not to oversell the day. Sailing remains the compromise choice at 5.2/10: the water is flat, but so is the available breeze. Cloud cover is forecast at 100%, despite no rain window indicated, and the air will feel closer to 9 C than the representative 11 C. Compared with the last week, the water activities remain consistently strong, though kayaking is a touch below the 9.3–9.7 scores earlier this week and boating slightly below the recent 8.8–9.0 range. Friday looks rougher and wetter, with winds up to 16.4 knots and waves reaching 0.7 m; Saturday eases, and Sunday through Monday look notably calmer again. Best bet: launch after dawn, use the glassy morning before the 10:36 AM low, and enjoy a day when the water is doing very little—which is exactly the point.
