Bar Island sandbar tide times by month
Where these tide times come from
We fit 18 tidal constituents to about 200 days of hourly ocean tide from the Copernicus Marine global ocean model, at the nearest sea grid point (44.42, -68.25), then predict any date with astronomical arguments and nodal corrections. In a two-week test our high and low water times differed from the model by a median of 4 minutes.
Local harbours, river flow, wind and air pressure shift real tides by tens of minutes and heights by tens of centimetres. For causeways and sea-floor walks, always follow the official safe crossing times posted on site.
Times are local (America/New_York). Heights are relative to mean sea level, not chart datum. Generated using E.U. Copernicus Marine Service information.
