Pick a spot by latitude and longitude and the chart snaps to the nearest NOAA tide station, or pin a station by its ID. The plugin adds: * A **Tide Chart (SeaLegs AI)** block that shows the live chart while you edit, with location and display settings in the block sidebar. * A **[sealegs_tides]** shortcode for the classic editor and page builders. #### Features * **Free, no API key** — install, add the block, publish. * **NOAA predictions** — the same harmonic predictions as the official NOAA tide tables. * **Several charts per page** — list every marina, ramp or charter dock on one page. * **Style-isolated** — each chart renders in its own Shadow DOM, so your theme and the chart cannot break each other. * **Loads only where used** — the widget script is added only to pages that contain a chart. The free chart covers US waters. International coverage is available on a paid plan; see [sealegs.ai/tide-widget](https://www.sealegs.ai/tide-widget). ### External services This plugin is an interface to the SeaLegs AI tide widget, a hosted service. On pages that contain a tide chart, the visitor’s browser connects to these services: * **SeaLegs AI widget CDN** (`cdn.sealegs.ai`) — loads the tide widget script and its styles. Sent: a standard browser request, including the page address as the referrer. * **SeaLegs AI API** (`api.sealegs.ai`) — returns tide predictions and nearby stations. Sent: the latitude, longitude and optional station ID set in the block or shortcode, and the page address as the referrer. * **NOAA CO-OPS API** (`api.tidesandcurrents.noaa.gov`) — for many US locations the widget fetches the public station list and predictions directly from NOAA. Sent: the station ID and date range. [NOAA privacy policy](https://www.noaa.gov/protecting-your-privacy) * **SeaLegs AI website** (`www.sealegs.ai`) — serves the small logo in the chart’s credit line. As with any web request, each of these services receives the visitor’s IP address and browser type. The widget sets no cookies and does not track visitors. It stores the visitor’s favorite stations in their own browser (localStorage) so favorites persist between visits; this never leaves the browser. SeaLegs AI [Widget Terms](https://www.sealegs.ai/widget-terms), [Terms of Service](https://www.sealegs.ai/terms-of-service) and [Privacy Policy](https://www.sealegs.ai/privacy-policy) apply. The chart shows a “Powered by SeaLegs AI” credit inside the widget. It is rendered by the service, not added by this plugin. ## Screenshots [⌊A tide chart on a published page, light theme.⌉⌊A tide chart on a published page, light theme.⌉[ A tide chart on a published page, light theme.

Paid plans add international coverage and white-label options. ### Can I put more than one chart on a page? Yes. Each chart mounts separately and the widget shares its fonts and styles between them. ### Can I see the chart while editing? Yes. The block shows the live chart in the editor and redraws it as you change the location, theme, units or height. ### How do I find a NOAA station ID? You usually don’t need one; the chart snaps to the nearest station. To pin a specific station, look it up at [tidesandcurrents.noaa.gov](https://tidesandcurrents.noaa.gov/). ### Does it work outside the United States? The free chart covers US waters. International coverage is on a paid plan; contact support@sealegs.ai. ### Where do I get help?
