🔍 Key Concepts

• Tidal current tables for Lynnhaven Roads (daily pages and the corresponding current diagram or rotary current table) • Relationship between DST (Daylight Savings Time), zone description (ZD +4), and standard time used in tables • How to interpret average set/direction of current between slack water and maximum flood/ebb

💭 Think About

• How do you convert 1000 DST (ZD +4) to the reference time used in the current tables for that year and location? • On 23 July, around that converted time, is the current in Lynnhaven Roads closer to a flood maximum, ebb maximum, or near a slack period? • Once you locate the correct time interval on the current diagram/table, what is the average direction of the current shown there?

✅ Before You Answer

• Confirm you are using the correct Lynnhaven Roads station (not a nearby reference or subordinate station). • Verify the time conversion from 1000 DST to the table’s standard time before reading the diagram. • Double-check that you are reading the average direction (set) for the correct time band on the current diagram, not the maximum rate or a different phase of the tide.
