Tide chart questions

Where do the Old Cock tide times come from?

High and low times come from NOAA CO-OPS station Westport Harbor (8447975). Heights are in feet relative to mean lower low water (MLLW), in the station's local time. This page requests the same predictions product as the Old Cock harbor briefing.

How current is this tide chart?

These are astronomical predictions. The page shows when Boat or Nope retrieved them from CO-OPS. The response is cached for up to 6 hours, the same window the harbor pages use, and the page itself refreshes about every 15 minutes.

Does the Old Cock tide chart include storm surge or observed water level?

The chart is the predicted tide. When CO-OPS reports a recent measured water level at this station, the Old Cock Go/No-Go page compares it with the prediction. This tide page does not add a separate water-level request.

Why is there one tide chart for this station?

Harbors that share station 8447975 use one canonical chart so the same curve is not published as dozens of near-duplicate URLs. The harbor pages for Bayside Marine & Auto, Hicks Cove, Kibby Ground, Lions Tongue link here.
