I just wanted a simple way to see weather and tidal information for where I like to paddle.

This example is hard-coded to West Point for weather, and Meadow Point (near Golden Gardens) for tide, but you can get your own widget code from here.

• National Weather Service (NWS) Station ID: https://api.weather.gov/stations/WPOW1/observations this has been offline since 2019, and the NWS's backlog of software development is so huge, I doubt it will ever get fixed.
• National Buoy Data Center (NBDC): This is a more reliable API, even if it only provides CSV data instead of JSON.
