Free Tide Chart Widget

Run a marina, harbor office, bait shop, charter operation, or fishing club? Put a live, interactive tide chart on your own website — the same NOAA-powered chart from USTideCharts, free, no signup, no API key. Paste one line of code and it stays current forever.

Add it in 30 seconds

  1. 1. Pick your location slug from the locations page — it's the last part of the URL (e.g. monterey, half-moon-bay).
  2. 2. Paste this snippet into your page, swapping the slug if needed:

The fine print

The widget is free for any website, commercial or not. Tide predictions come from NOAA CO-OPS and refresh automatically — you never need to update anything. The chart is fully interactive: visitors can pan, zoom, and hover just like on USTideCharts.

We ask only that the small "USTideCharts" credit link stays visible. Currently available for 20 California locations, with more states coming — if you need a location we don't cover yet, reach out and we'll usually add it within a week.
