The tide enters from the SEA - My favorites quotes from the famous Bowditch

"In the OCEAN, the tide may be in the nature of a progressive wave with the crest moving forward, a stationary or standing wave which oscillates in a seesaw fashion, or a combination of the two. Consequently, caution should be used in inferring the time of tide at a place from tidal data for nearby places. In a river or estuary, the tide enters from the SEA and is usually sent upstream as a progressive wave so that the tide occurs progressively later at various places upstream."
