This tide chart is very accurate and user friendly.
The "x" indicates the real time status of the tide.
Strong on shore winds will create higher tides than indicated on the chart and advance the incoming tide perhaps as much as an hour or so.
A strong offshore wind will create the tides to be lower than indicated on the chart and delay the incoming tide as much as a couple of hours.
Anyway, its a great tool to determine when the incoming tide will occur and its strength !
