Lameshur Bay, St John, VI Daily Water Report — October 7, 2026

Lameshur Bay gets a qualified green light for sail-powered plans and a decent yellow light for most other water time: useful conditions, but not the sort that rewards complacency. Sailing leads the board at 8.1/10, with an easterly-southeasterly breeze around 11 knots and gusts near 19 knots providing real drive. The tradeoff is a short, mixed sea: waves run about 1.0 to 1.3 metres, with 0.74 m of swell from 126 degrees at just 4.6 seconds and wind waves around 0.58 m at 3 seconds. That is manageable for capable crews, but it will keep small craft busy. The best all-around window is late afternoon into evening, especially around the 6:44 PM high tide, when the day’s calmest predicted wave height—0.98 m—arrives near 8 PM. Daylight ends at 6:04 PM, so that smoother patch is more useful to boaters with proper night readiness than to paddlers or divers. For fishing, the 8:50-10:50 AM major solunar period lines up closely with the 11:35 AM low tide, while the evening major period runs 8:50-10:50 PM. Fishing rates 7.4/10, helped by the timing, rising pressure near 1014 hPa, and workable wind rather than glassy water. Diving earns 7.2/10 in very warm 29.5 C marine water, but surface chop and gusts remain the limiting factors. The reported 7.66 km atmospheric visibility is not an underwater-visibility reading, so treat water clarity as unconfirmed. Kayaking is the more conditional choice at 5.9/10: the 10.8-18.1-knot wind range, gust potential, and short-period waves favor experienced paddlers who can stay conservative. Boating is middling at 6.6/10 for much the same reason. Rain is possible throughout the day, though representative precipitation is light. Compared with late September, the wind is near the familiar 11-knot range, but boating and diving score a little below several recent stronger days; sailing remains reliably good rather than exceptional. The sea should hold near 1.0-1.1 m through Sunday, then ease toward 0.7-0.8 m by Tuesday as winds also relax, though rain chances remain elevated before improving. Best bet: rig for a brisk sail, then let the evening high tide be the day’s smoother encore.
