Tide predictions: NOAA CO-OPS , station 9450406 · NOAA's page for Block Island, Tlevak Narrows · retrieved Oct 18, 2026.
Times are local to the station (America/Sitka, AKST); daylight saving is applied where the zone observes it. Heights are relative to MLLW ; negative heights are below that datum. Feet are converted from NOAA's metric values and rounded to a tenth.
Predictions are estimates of astronomical tides; actual water levels can differ due to weather and other conditions. Not for navigation or determining safe clearance. Consult official nautical charts, real-time observations, forecasts and local authorities for navigational decisions.
