Lameshur Bay, St John, VI Daily Water Report — August 23, 2026

Sailing owns Lameshur Bay today. At 9.2 out of 10 it sits well clear of the rest of the board, and the Open-Meteo picture behind that score is a clean easterly working day: about 16 knots from the east, holding in a fairly tight 12-to-16-knot band under only 22 percent cloud, with seas staying in a modest 1.0-to-1.2-meter range. That is a suitability call, not a safety declaration, but it is the day’s most decisive invitation. Everything else asks for a tradeoff. Diving at 7.2 and surfing at 6.9 are both workable if you accept short-period energy—roughly 1.1 meters at a little over five seconds, a 0.96-meter swell at 4.75 seconds from 108 degrees, and a smaller wind-wave chop on top. Boating comes in at 6.1. Fishing is only 5.5 and wildlife 5.0, and kayaking is the weakest card at 4.6, which tracks the same breeze, a 0.6-meter-per-second current setting toward 288 degrees, and those persistent one-meter seas. If you paddle, you are choosing the tax, not wishing it away. The kindest window is mid-to-late afternoon. Waves ease to their daily minimum near 1.04 meters around 16:00, overlapping the 15:21–17:21 solunar major and the long climb from a 0.01-meter low at 10:09 toward a 0.29-meter high at 19:09. Pressure is steady near 1015 hectopascals. Air is warm—representative 29.3°C, feeling like 31.2 in 73 percent humidity—while marine surface water is 29.3°C, half a degree above average. Measurable rain stays at zero even through a long 02:00–20:00 rain window, and atmospheric visibility is a wide 18.3 kilometers, which is not a claim about what you will see underwater. The sharpest gust, 22 knots, is slated for 02:00, so the overnight major from 03:21–05:21 arrives with more breeze than polish. Moonrise is 11:36 under a waxing gibbous 76 percent lit. Yesterday’s reconstructed scores were kinder to anglers and paddlers—fishing 6.4, kayaking 5.7—on slightly lighter 14.9-knot wind and 28.8°C air. Sailing has improved from 8.6; diving and boating barely moved. Through the week, the marine forecast holds waves near a meter on the 24th, then builds toward 1.3–1.4 meters by the 26th through the 28th as peak winds climb into the high teens and rain chances linger in the 37-to-51-percent range. Best bet: take the easterly and sail the afternoon while the sea is as small as it will get.
