Prince Rupert, BC Daily Water Report — August 24, 2026

Sailing takes Prince Rupert’s harbor today, and it is not a close call. A representative 13-knot SSE breeze, gusting into the mid-30s, finally gives canvas something to work with while it turns the same water awkward for small craft. Sailing scores 8.2; kayaking sits at 4.7 and boating at 5.9. Read those as suitability, not a safety stamp. The morning is the tax. The day’s strongest gust, 35.6 knots, is timed for 9:00, almost on top of the 1.72-metre low at 9:22 a.m. Cloud cover is total, humidity 96 percent, and atmospheric visibility only about 2.4 kilometres under a rain window that runs the clock, even if the representative total is a light 0.7 millimetres. Thunderstorms are in the forecast weather. Air hangs near 15 degrees and feels cooler. Short wind waves near 0.6 metres on a 2.8-second period will feel jumpy, and a 0.6-metre-per-second current toward the northwest adds another layer for anyone underpowered. The usable stretch is later. High water of 5.06 metres at 3:52 p.m. overlaps the afternoon solunar window from 16:45 to 18:45. Pressure is already 1014 hectopascals and rising, which helps fishing to a 6.2 even as the wind keeps it short of yesterday. Waves hold 0.4 to 0.6 metres with a 3.4-second period and a small swell from the southwest, so surfing is a middling 5.6—texture, not a session. Surface water is 13.9 degrees, half a degree above average. Diving lands at 6.7 on wind, waves, and that cool water; the haze aloft is not a window into the water column. Wildlife scores 7.3 from solunar timing, the morning low, and the breeze. Seas ease toward 0.38 metres near 23:00 if anyone is still out. Yesterday’s reconstructed day was the inverse: about 1.5 knots of wind, boating and kayaking at 8.2, fishing 7.8, and sailing only 4.6. The harbor flipped overnight. Through the 30th the marine forecast eases to mostly 0.1–0.4-metre seas and peak winds of 6 to 8 knots, with rain still in the mix. Best bet: if you have a sail ready, use this afternoon’s breeze and save the paddle for the quieter days the harbor still owes you.
