Install `signalk-tides` from the SignalK Appstore or manually by running `npm install signalk-tides` in the SignalK server directory (`~/.signalk`).\n\n2. Optionally go to the plugin settings in \"Server =\u003e Plugin Config =\u003e Tides\" and configure which source to use.\n\n## Usage\n\nThis plugin depends on `navigation.position`.\n\nIt publishes the following [tide data](https://signalk.org/specification/1.7.0/doc/vesselsBranch.html#vesselsregexpenvironmenttide):\n\n* `environment.tide.heightHigh`\n* `environment.tide.timeHigh`\n* `environment.tide.heightLow`\n* `environment.tide.timeLow`\n* `environment.tide.heightNow`\n* `environment.tide.stationName`\n\n### Tides resource\n\nIt also registers a `tides` resource, which returns tide predictions for yesterday and the next 6 days for the vessel's position.\n\n```\n$ curl http://localhost:3000/signalk/v2/api/resources/tides\n```\n\n##### Request Parameters\n\n* `date` (optional) - the date for which to get the tide predictions in the format `YYYY-MM-DD`. Default: yesterday's date.\n\n##### Response\n\n```json\n{\n   \"extremes\" : [\n      {\n         \"time\" : \"2025-03-29T00:45:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : 0.025\n      },\n      {\n         \"time\" : \"2025-03-29T07:20:00.000Z\",\n         \"type\" : \"High\",\n         \"value\" : 1.928\n      },\n      {\n         \"time\" : \"2025-03-29T13:18:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : 0.044\n      },\n      {\n         \"time\" : \"2025-03-29T19:45:00.000Z\",\n         \"type\" : \"High\",\n         \"value\" : 1.815\n      },\n      {\n         \"time\" : \"2025-03-30T01:24:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : 0.164\n      },\n      {\n         \"time\" : \"2025-03-30T07:52:00.000Z\",\n         \"type\" : \"High\",\n         \"value\" : 2.024\n      },\n      {\n         \"time\" : \"2025-03-30T14:05:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : -0.131\n      },\n      {\n         \"time\" : \"2025-03-30T20:43:00.000Z\",\n         \"type\" : \"High\",\n         \"value\" : 1.733\n      },\n      {\n         \"time\" : \"2025-03-31T02:05:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : 0.334\n      },\n      {\n         \"time\" : \"2025-03-31T08:27:00.000Z\",\n         \"type\" : \"High\",\n         \"value\" : 2.084\n      },\n      {\n         \"time\" : \"2025-03-31T14:53:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : -0.247\n      },\n      {\n         \"time\" : \"2025-03-31T21:44:00.000Z\",\n         \"type\" : \"High\",\n         \"value\" : 1.632\n      },\n      {\n         \"time\" : \"2025-04-01T02:48:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : 0.517\n      },\n      {\n         \"time\" : \"2025-04-01T09:06:00.000Z\",\n         \"type\" : \"High\",\n         \"value\" : 2.094\n      },\n      {\n         \"time\" : \"2025-04-01T15:46:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : -0.29\n      },\n      {\n         \"time\" : \"2025-04-01T22:51:00.000Z\",\n         \"type\" : \"High\",\n         \"value\" : 1.529\n      },\n      {\n         \"time\" : \"2025-04-02T03:37:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : 0.695\n      },\n      {\n         \"time\" : \"2025-04-02T09:49:00.000Z\",\n         \"type\" : \"High\",\n         \"value\" : 2.05\n      },\n      {\n         \"time\" : \"2025-04-02T16:43:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : -0.263\n      },\n      {\n         \"time\" : \"2025-04-03T00:04:00.000Z\",\n         \"type\" : \"High\",\n         \"value\" : 1.448\n      },\n      {\n         \"time\" : \"2025-04-03T04:35:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : 0.847\n      },\n      {\n         \"time\" : \"2025-04-03T10:39:00.000Z\",\n         \"type\" : \"High\",\n         \"value\" : 1.957\n      },\n      {\n         \"time\" : \"2025-04-03T17:50:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : -0.189\n      },\n      {\n         \"time\" : \"2025-04-04T01:24:00.000Z\",\n         \"type\" : \"High\",\n         \"value\" : 1.421\n      },\n      {\n         \"time\" : \"2025-04-04T05:49:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : 0.946\n      },\n      {\n         \"time\" : \"2025-04-04T11:40:00.000Z\",\n         \"type\" : \"High\",\n         \"value\" : 1.837\n      },\n      {\n         \"time\" : \"2025-04-04T19:07:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : -0.11\n      },\n      {\n         \"time\" : \"2025-04-05T02:40:00.000Z\",\n         \"type\" : \"High\",\n         \"value\" : 1.455\n      },\n      {\n         \"time\" : \"2025-04-05T07:19:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : 0.958\n      },\n      {\n         \"time\" : \"2025-04-05T12:53:00.000Z\",\n         \"type\" : \"High\",\n         \"value\" : 1.728\n      },\n      {\n         \"time\" : \"2025-04-05T20:25:00.000Z\",\n         \"type\" : \"Low\",\n         \"value\" : -0.061\n      }\n   ],\n   \"station\" : {\n      \"name\" : \"Rincon Point, Pier 22 1/2\",\n      \"position\" : {\n         \"latitude\" : 37.79,\n         \"longitude\" : -122.387\n      }\n   }\n}\n```\n\n## Sources\n\n- [Neaps](https://github.com/neaps/neaps)\n  - Offline, open source, runs locally\n  - Coverage: Regional — United States and territories (currently)\n- [NOAA](https://tidesandcurrents.noaa.gov/web_services_info.html)\n  - Online (NOAA web services)\n  - Regional — United States and territories\n- [WorldTides API](https://www.worldtides.info/)\n  - Online (requires API key, subject to API quotas)\n  - Coverage: Global - station and model coverage varies by location\n- [StormGlass.io](https://stormglass.io/)\n  - Online (requires API key)\n  - Coverage: Global - aggregated marine data;
